Re: [Matplotlib-users] Draping an image over topography in Basemap
I had just been looking into this myself. My starting point would be this example: http://stackoverflow.com/questions/13570287/image-overlay-in-3d-plot-using-python but instead of the hard-coded '10' as the z values in plot_surface, put in whatever data or function of x and y that you want. Using x+y seemed to do what I expected. Is that what you're looking for?

[Matplotlib-users] twiny and AxisDivider
I'm trying to do a twiny setup on one of the Axes generated from a make_axes_locatable().append_axes() call. The new axis generated from twiny() seems to span the entire window though. Here's the code: from matplotlib.pyplot import * import numpy as np from mpl_toolkits.axes_grid1 import make_axes_locatable ax_c = subplot(111) ax_c.plot(np.linspace(0,10)) divider = make_axes_locatable(ax_c) ax_t = divider.append_axes(top, size=1.2, pad=0.1, sharex=ax_c) ax_r = divider.append_axes(right, size=1.2, pad=0.1, sharey=ax_c) ax_r.plot(np.linspace(0,50)) ax_t.plot(np.linspace(0,25)) ax_ty = ax_r.twiny() ax_ty.plot(np.linspace(-50,0)) show() If you get the idea of what I'm trying to do, other suggestions involving AxesGrid, subplots, or otherwise are welcome. AxesGrid seems to require that I have all four plots in a 2x2 grid (in the above code there are only 3), and using subplots would seemingly require the rightmost plot to span the height of the other two.

Hello, I have a similar problem to: Suppose I plot a line from (0,0) to (1,1.5) to (2,2). Now I want to mark (1,1.5) with a green circle. How is that done? I am performing a curve fit and also showing a distribution in my plot. In order to help the reader to evaluate the result I would like to draw certain boundaries (vertical and horizontal line). While I am aware on how to draw such lines, I would like to know wheather there are some functions in matplotlib which help me to retrieve the coordinates a) at which two curves intersect b) at which a distribution reaches a certain value? Example: How do I get the y-axis value which is reached by the green curve in http://matplotlib.sourceforge.net/_images/histogram_demo_extended_021.png a x-axis value of in 175? I could proably use a solver from numpy like http://docs.scipy.org/doc/numpy/reference/generated/numpy.linalg.solve.html#numpy.linalg.solve but if I plot a distribution, the equation of the envelove is unknown at the first place.

[Matplotlib-users] Multicolor line with dates
Hi all,
I'm relatively new to matplotlib but have been generating some plots
without too much trouble over the last couple of weeks. Now I'm
getting trickier...
I have a timeseries plot that plots a few values against an x-axis of
dates. I *really* want to have my key line change color to red when
the values are *critical* but am having no success working with the
examples I can find. It appears that with dates as an x-axis,
something else needs to happen.
Here is the code:
# prep for multicolored line -- here I simply generate the list of
required color values
r = colorConverter.to_rgba('r')
b = colorConverter.to_rgba('black')
color = list()
for f in daily_fvfm:
if f = -0.4:
color.append(r)
else:
color.append(b)
# create the linecollection
points = zip(date_range, daily_fvfm)
segments = zip(points[:-1], points[1:])
lc = LineCollection(segments, colors = color) --- here is where I
get the error at run-time (see below)
# create a figure with two subplots and add a
# second axis to the first figure
fig = mpl.figure(1)
fig.set_size_inches((10,5))
ax1 = fig.add_subplot(211)
ax2 = ax1.twinx()
ax3 = fig.add_subplot(212)
# plot the sst and then the par
ax1.plot(date_range[start_index:end_index],
daily_sst[start_index:end_index], 'b-')
ax1.plot(date_range[start_index:end_index],
daily_par[start_index:end_index], color='darkgoldenrod')
# then plot Fv/Fm
#ax2.plot(date_range[start_index:end_index],
daily_fvfm[start_index:end_index], lw='2', color='black')

Can a multicolor line be done with dates. if so, what is the

Re: [Matplotlib-users] Basemap to KML polygon
Looks like I've done a mistake with my last post, sorry Eli... I know how to save datas to a shapefile with the OGR library but only for points datas. I'll appreciate if somebody can point me how to save a filled contour map basemap into a polygon shapefile, can't find any example with google. What do you really want to save here? A basemap with a contour surface overlayed can be viewed as a assembly of various layers. So this is like the result of the gis operations when you launch the map composer to finish your map. If you want to create a raster file from the contour part plotted over a basemap I think the python bindings of gdal will get you started. http://pypi.python.org/pypi/GDAL/ I succeded into writing a tiff file from a gdal array. I don't know how to write a vector file from python with ogr or shapely. But these questions are better to be asked on the gdal list.: So about interpolating to a contour look at shapely. Writing should be accomplished with ogr. That said, I only have testing experience with writing geodata with python. The overkill may be to invoke the respective GRASS command by a script. I would appreciate if you would tell us what you use by the end.

[Matplotlib-users] plotting a contour map from CSV file
Dear Matplotlib-Users, I am tryring to create a contour plot over a basemap. My main problem is creating the array for the Z values as a basis for the plt.contour command from a CSV file where latitude, longitude and value are stored column-wise: lat;lon;value 50; 10; 6 ... The data represents a regular spaced grid with a datapoint each 0.25 degrees. I tried various possibilities but didn't have success: 1) following simpletest.py from the basemap examples: X, Y = meshgrid(data[:,1], data[:,0]) Z = data[:,2] m.contourf(x,y, Z) = Error: Z must be a 2D array - How do I get Z to be a 2D array? 2) using the griddata package Here I was nearly without orientation how to call griddata correctly. 3) Using the python bindings of ogr Any examples on this one? From my above demonstrated methods the following questions arrise: What is the preferred way to plot - Points stored in the above descripbed format (lat, lon, value)? - Interpolate a grid of data points by using different interpolation methods like inverse distance wheighting, natural neighbor interpolation, etc. to get a contour map?

Re: [Matplotlib-users] plotting a contour map from CSV file
Hello Jeff, - Points stored in the above descripbed format (lat, lon, value)? This one I solved using a m.scatter() function - Interpolate a grid of data points by using different interpolation methods like inverse distance wheighting, natural neighbor interpolation, etc. to get a contour map? For interpolation of irregular, randomly distributed data points see http://www.scipy.org/Cookbook/Matplotlib/ Gridding_irregularly_spaced_data. However, if there is some structure to the data grid then it's probably better not to use these approaches. The problem is that although regular spaced the grid is still to large to countour to a nice map. I will play a bit more with contour and other interpolation functions. I tried griddata: 2) using the griddata package Here I was nearly without orientation how to call griddata correctly. I tried again. Here is what I got: x = data[:,1] y = data[:,0] z = data[:,2] X, Y = mlab.meshgrid(x, y) X, Z = mlab.meshgrid(x, y) # zi = griddata(x,y,z,xi,yi,**kwargs) Z = grid.griddata(x,y,z, X, Y) plt.contour(X,Y, Z) = ValueError: output grid defined by xi,yi must be monotone increasing The coordinates are stored in a way that first longitude (x) increases and then the latitude (y) increases. 10 6.0 4 10 6.25 3 10 6.50 2 10 6.75 1 10 6.0 6 11 6.25 7 11 6.50 6 11 6.75 9 12 6.0 4 What how do I need to arrange my data to get it monotone increasing for griddata?

Re: [Matplotlib-users] plotting a contour map from CSV file
Hello, thanks. I checked again from contour_demo.py of the basemap distribution. There lats, lons are uniquely monoton increasing from 0-360 and from -90 to 90. In my case data is written row-by-row: * increasing from lowest latitude western most longitude to easternmost longitude and then increasing each rows in the same manner to the northermost latitude (see below). So, as you said, it's a question of re-aranging the data. that it fits the to the way m.contour expects the 2-D array. Also, since the grid is still coarse, I would need to apply some smoothing afterwards. What do you recommend for that? I don't know how I can do this easily by hand. May you give me some guidance here, please? But I may just convert it to a shape file using GIS then load it with the shapefile interface you wrote. What would you see as most convenient way? If I produce maps with a GIS but want to use matplotlib for the map plotting, what would be the preferred export format? Any gdal format?

[Matplotlib-users] axes scale factor not showing
Hi,
When matplotlib uses an axis multiplier, as in x-axis in the script
below, the scale factor is not positioned properly on the figure as is
shown in the attached picture. The 'x1e+30' in the bottom right corner
is clipped unless I enlarge the window.
import Numeric, gtk
import matplotlib
matplotlib.use('GTK')
import matplotlib.figure, matplotlib.axes, matplotlib.backends.backend_gtk
# data
values = Numeric.array([-1e30, -1e30, 0,1,2,3,4,5,6,7,8,9], 'd')
# figure
figsize=(6,3)
figure = matplotlib.figure.Figure(figsize=figsize)
canvas = matplotlib.backends.backend_gtk.FigureCanvasGTK(figure)
axes = matplotlib.axes.Subplot(figure, 111)
figure.add_axes(axes)
axes.hist(values, bins=10)
axes.set_title('X-scale multiplier is hidden', fontsize=10)
# window to display
window = gtk.Window()
window.connect('destroy', gtk.main_quit)
window.add(canvas)
window.show_all()
gtk.main()
I can use the axes position to work I guess but that seems rather
unsatisfactory as I'll have to figure out when it's being displayed or
not, font sizing and spacing blah blah blah.
Is there an easier way around this (or a fix?)? I'm using v0.90.0
Thanks
Tim

[Matplotlib-users] Newbie / plot([1,2,3]) issues / Csound
Hi Folks, I've been using Python about 9 months or so, inspired mainly by the desire to work more effectively with Csound. Python has been a revelation to my creativity music making ambitions, probably the most satisfying consuming creative diversion i have ever made. Ive today installed Numpy Matplotlib (on XP), set TKagg as my backend in the matplotlibrc file. When i try run the plot([1,2,3]) example (im working from the matplotlib user guide pdf document, which generally looks very nice, much like matplotlib itself dare i say..) a TK window opens, but nothing appears in it, the hourglass continues ad infinitum, the process eventually hangs. This also happened when i ran IDLE from the command line (something i'd never done before) with the -n flag... Idle's window tells me that an output plot object was sucessfully created however... So, err, what could the problem be? I'm using standard windows binary installers for everything, Python 2.5, Numpy 1.0.3.1, Matplotlib 0.91.2. Everything imports ok. On a less immediate note, i would like to address people to this post i made earlier today on the Tkinter list http://www.nabble.com/drawing-multiple-functions-on-the-canvas-td16064458.html for some advice /or assistance. Whilst i can see Matplotlib as being useful to my DSP musicmaking world in a number of adhoc ways, i'm primarily interested in trying to find shortcuts methods to defining arbitrary functions with the mouse(/wacom) input, recording the x/y(/z) data into an array, refreshing / displaying that data to the screen. There seems to be plenty around to help me scribble on a canvas, but not in a way that allows me to keep unique, function like, myfunc[x] = y lists display them to screen. I've been aware for awhile now that Matplotlib may offer me some elegant more than adequate solutions to displaying mathematically defined functions, but can it help me design by hand output overlays of arbitrary xy patterns relationships at all? All i would need to do is then output my input created XY arrays / lists to .txt file, bring the data into my existing Python / Csound environment for immediate easy use. So if anyone has any advice on the simplest, lowlevel way i might go about attempting this (with or without Matplotlib) that'd be ace. But essentially i am talking about displaying refreshing plots after all, right? so hopefully this is a good place to start. Spoilt for choice, swamped by info, uncertain how best to proceed. many thanks Tim - *** www.phasetransitions.net hermetic music * python * csound * possibly mindless ranting various werk in perpetual delusions of progress -- View this message in context: http://www.nabble.com/Newbie---plot%28-1%2C2%2C3-%29-issues---Csound-tp16065553p16065553.html Sent from the matplotlib - users mailing list archive at Nabble.com. - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Matplotlib-users] Newbie / plot([1,2,3]) issues / Csound
Thanks Darren, Here's a copy of what IDLE is printing to the screen (i'm using idle because I'm lazy don't like typing filepaths in full ; ) - a lot of my python stuff is about avoiding doing exactly this for csound repeatedly... ) There's nothing specific re the Tk window crash that i can see Many other .py matplotlib examples I have tried work - just (so far) not the plot([1,2,3]) command, nor Anim.py that i have taken from the distributed examples zip. In the case of Anim.py, the window launches displays the animation sucessfully - however any attempt at window interaction results in hang crash. My hunch is the problem is Tk(?), not Matplotlib. I have to admit, the font choice seems like an unusual / unexpected one (see below) Anyway, thanks for taking a look, please advice if anything you see below is illuminating on any issue at all. from pylab import * loaded rc file C:\Python25\lib\site-packages\matplotlib\mpl-data\matplotlibrc matplotlib version 0.91.2 verbose.level debug interactive is True units is False platform is win32 loaded modules: ['pylab', '_bisect', 'xml.sax.urlparse', 'distutils', 'tkFileDialog', 'random', 'datetime', 'idlelib.macosxSupport', 'matplotlib.tempfile', 'distutils.sysconfig', 'encodings.encodings', 'pytz.cStringIO', 'xml', 'struct', 'tempfile', 'xml.sax.urllib', 'pytz.tzinfo', 'idlelib.cPickle', 'matplotlib.__future__', 'imp', 'collections', 'idlelib.MultiCall', 'pytz.os', 'zipimport', 'string', 'SocketServer', 'repr', 'idlelib.string', 'idlelib.bdb', 'pytz.datetime', 'itertools', 'distutils.re', 'idlelib.SocketServer', 'ConfigParser', 'bisect', 'signal', 'idlelib.IOBinding', 'xml.sax.types', 'threading', 'tkMessageBox', 'idlelib.warnings', 'xml.sax.xmlreader', 'matplotlib.pytz', 'idlelib.struct', 'idlelib.cStringIO', 'idlelib.linecache', 'locale', 'idlelib.threading', 'idlelib.TreeWidget', 'idlelib.rpc', 'idlelib.re', 'encodings', 'idlelib.RemoteDebugger', 'idlelib.tempfile', 'shutil', 'dateutil', 'idlelib.codecs', '_tkinter', 'bdb', 'matplotlib.warnings', 'matplotlib.string', 'pytz.pytz', 'urllib', 'matplotlib.sys', 're', 'idlelib.RemoteObjectBrowser', 'ntpath', 'idlelib.imp', 'idlelib.locale', 'idlelib.thread', 'math', 'idlelib.Debugger', 'Tkinter', 'idlelib.traceback', 'idlelib.marshal', 'UserDict', 'distutils.os', 'matplotlib', 'Queue', 'idlelib.StackViewer', 'codecs', 'idlelib.copy_reg', 'md5', '_locale', 'idlelib.AutoComplete', 'matplotlib.sre_constants', 'socket', 'thread', 'idlelib.time', 'traceback', 'weakref', 'idlelib.socket', 'idlelib.CallTipWindow', 'os', 'marshal', 'pytz.tzfile', '__future__', 'nturl2path', 'idlelib.AutoCompleteWindow', 'idlelib.tkFileDialog', 'cStringIO', '_sre', 'xml.sax.sys', '__builtin__', 'matplotlib.copy', 'matplotlib.re', 'operator', 'distutils.string', 'select', 'idlelib.os', 'idlelib.ZoomHeight', 'matplotlib.datetime', 'idlelib.ConfigParser', 'errno', '_socket', 'binascii', 'sre_constants', 'matplotlib.md5', 'types', 'pytz.sys', 'xml.sax.handler', 'idlelib.__builtin__', 'idlelib.tkMessageBox', 'xml.sax.os', 'cPickle', 'matplotlib.xml', 'idlelib.HyperParser', 'encodings.cp1252', 'pytz', 'matplotlib.pyparsing', 'idlelib.repr', 'copy', 'idlelib.Queue', '_struct', '_types', 'matplotlib.dateutil', 'hashlib', 'keyword', 'idlelib.keyword', 'xml.sax.saxutils', 'idlelib.__main__', 'idlelib.sys', 'encodings.aliases', 'matplotlib.fontconfig_pattern', 'exceptions', 'sre_parse', 'pytz.bisect', 'distutils.distutils', 'FixTk', 'copy_reg', 'sre_compile', 'xml.sax', '_hashlib', '_random', 'pytz.struct', 'site', 'SimpleDialog', '__main__', 'idlelib.types', 'matplotlib.weakref', 'urlparse', 'tkCommonDialog', 'matplotlib.os', 'strop', 'encodings.codecs', 'gettext', '_codecs', 'matplotlib.rcsetup', 'nt', 'pytz.sets', 'xml.sax._exceptions', 'idlelib.PyParse', 'xml.sax.codecs', 'stat', '_ssl', 'warnings', 'encodings.types', 'sets', 'sys', 'idlelib.Tkinter', 'idlelib.CallTips', 'idlelib.configHandler', 'idlelib.WindowList', 'idlelib.SimpleDialog', 'os.path', 'idlelib.ScrolledList', 'pytz.gettext', 'distutils.sys', 'matplotlib.distutils', '_weakref', 'idlelib.ObjectBrowser', 'idlelib', 'Tkconstants', 'distutils.errors', 'matplotlib.matplotlib', 'linecache', 'matplotlib.shutil', 'time', 'idlelib.select', 'idlelib.run'] numerix numpy 1.0.3.1 $HOME=C:\Documents and Settings\Tim CONFIGDIR=C:\Documents and Settings\Tim\.matplotlib Using fontManager instance from C:\Documents and Settings\Tim\.matplotlib\fontManager.cache matplotlib data path C:\Python25\lib\site-packages\matplotlib\mpl-data backend TkAgg version 8.4 plot([1,2,3]) findfont found Bitstream Vera Sans, normal, normal 400, normal, 12.0 findfont returning c:\program files\celemony\melodyne.3.0\vstplugins\uhe_data\podolski\fonts\vera.ttf [matplotlib.lines.Line2D instance at 0x018383A0] cue blank TK window with infinite hourglass - *** www.phasetransitions.net hermetic music * python * csound * possibly mindless ranting various werk in perpetual
Re: [Matplotlib-users] import error with Basemap
Timmie: It's possible that the windows installer is missing the httplib2 module - I don't have access to windows right now to check. Could you try installing httplib2 and let me know if that fixes it? Installing httplib2 solved the issue. Has this dependancy on httplib2 been introduced in the last update? What are the merits of this dependency? Could it be made option? Like that I would only need to have httplib2 if I use functions that load maps from the web?

Re: [Matplotlib-users] Missing labels/text(s) in plots generated via cgi script.
I deleted my /.matplotlib/fontManager.cache file and ran the script again, and now everything is working fine. Thank you for your help. It appears to be finding wadalab-gothic as the font, which is a Japanese font. Now, *why* it is doing that is the million dollar question. It should (by default) by loading the Bitstream Vera Sans font (Vera.ttf) from /usr/local/lib/python2.4/site-packages/matplotlib/mpl-data/fonts/ttf. I would verify that it is there and readable by the user that the CGI script runs under. You can try refreshing the font-finding cache by removing the file ~/.matplotlib/fontManager.cache. If that doesn't provide any clues, can you send me the fontManager.cache (probably best off-list), and I'll see what fonts it *is* finding, again hopefully providing more clues. One other thing to note about the output: it is loading the matplotlibrc from /home/www/www/cgi-bin/, (since it is present), and not from /home/private/mpl/.matplotlib/. Perhaps there is something incorrect in that matplotlibrc file. Cheers, Mike Tim Lewis wrote: Can you set verbose.level to debug-annoying in your matplotlibrc and send us the output? That may help provide an explanation as to why the text is not appearing.

[Matplotlib-users] new free matplotlib based software useful for you?
Hello, My company, Resonon, is releasing our free (as in beer) software package, Spectronon. Spectronon is written in python and utilizes matplotlib, numpy, PIL, and scipy. Spectronon's main purpose is analyzing hyperspectral data (images with many more bands of color than the traditional 3: red, green, blue). It can also be useful for more traditional image processing. Perhaps of most interest here, it is a quick way to get access to a command line with a bunch of useful libraries, plotting, and image viewing. It's packaged as a basic exe installer. There is also a fairly simple plug-in architecture for extending some of Spectronon's behavior. As the main developer, I am very thankful for all the good work that gets put in to all these underlying libraries, and I hope that in getting this software out for free, it can in turn support more academic and research applications of python and its libraries. The release will also help me expose bugs, hopefully get more people interested in writing plug-ins for Spectronon, and help me learn other ways to improve the code base. While the source code is not presently open, the API is open in order to support writing plug-ins. Here are some screenshots: http://www.spectronon.com/wiki/index.php?title=Screenshots I recommend users on this list go directly to the developer docs here: http://www.spectronon.com/wiki/index.php?title=Setup_a_Simple_Development_Environment as this tutorial will step you through the aspects of Spectronon of most probable interest. Links to the download, support forums, and more docs are available at http://www.spectronon.com Thanks very much. I hope it's a fun ap for folks, and I greatly appreciate any questions, feedback, or comments as we begin to get this project off the ground.

Re: [Matplotlib-users] problems building/installing
My understanding is that currently the best way to get all these packages (wxpython, matplotlib, numpy, etc) running together on os x is via these packages: http://pythonmac.org/packages/ at least, I can say for sure that the 2.5 builds worked without a hitch for me. Its a little tough right now that os x doesn't have one python install to rule them all. Instead, there are about 5 (not an actual count) ways to do it, most with gotchas. tim Simson Garfinkel wrote: Alas, tried the easy_install matplotlib.

Re: [Matplotlib-users] matlab, idle, interactivity and teaching
I've had similar problems running wxPython code under certain IDEs where things can go very poorly (dramatic crashing, or it just wont execute). At least with the wx or wxagg backends, I have no trouble running matplotlib demos such as ellipse_demo.py from inside eclipse+pydev. -tim Gary Ruben wrote: I have to agree with Giorgio in general. Unfortunately, the threading support required by matplotlib isn't implemented in pyScripter, which means that it's a nice environment until you want to do some plotting, when it becomes a bit flaky.
