[Matplotlib-users] Multiple Y Axes redux
Hi there, I know this has been discussed in the past, but I was looking through some of the history and I'm not sure what the exact situation is. I think multiple y axes on the same side of the graph is unsupported officially, but can be hacked together somehow, is that right? Is there an example of such a hacked together method somewhere that I could look at? There may be a simpler way to do what I'm trying to do... I'm not trying to make several different axes, I'm trying to have a logarithmic axis on the left, but have three different scales (ie 1, 10, 100 on one, 10, 100, 1000 on another, 100, 1000, 1 on the final one). Is there a way to manually label the ticks on the axis "1 10 1000" and so on? I think that might do in a pinch, then I could just divide the plotted values by the correct scaling factor. Do you guys think that would be the way to go? And if that is possible, is it possible to have the tick labels be different colours for the different numbers so it shows which scale is for which line on the graph? I guess I'm not hopeful for that... Instead could I put in a bit at the bottom of the graph to highlight which markers go to which axis? Something like this (for x, o and * data markers on the chart): | | | | | | | | |_* | |_o |_x Thanks a lot, sorry if this question is kind of hard to follow... Please let me know if more clarification is needed!

[Matplotlib-users] shiftgrid 'cyclic point not included' error
Hi all, I am getting a 'cyclic point not included' error using shiftgrid on a grib file from NOAA. I've checked and it seems that the file has the lons from 0 to 359.5 every .5 degree but I get that error whenever I try to run this. What I need to achieve is to shift the grid from 0 / 360 to -180 / 180 so that I can create a map over Great Britain. I am using a Cassini projection.

Hi Jeff, Thanks for the quick reply! I've updated to the latest shiftgrid and now I get the chart :D I still have a small issue as there is a half degree sliver missing from the mapping at the greenwich meridian. Any idea how to solve that issue?

Re: [Matplotlib-users] shiftgrid 'cyclic point not included' error
Hi Jeff, Here is the whole script: http://old.nabble.com/file/p27826457/_test_shiftgrid.py _test_shiftgrid.py And here are the grib data files: http://socalscubainfo.com/downloads/GRIB2_files.zip Also, if there is not too much to ask, is there a sample anywhere that shows how to use shiftgrid for a mercator projection? If you look at the script, I was initially trying to make the images using the mercator projection (there is a commented basemap function there) but it would display just the data starting from the origin. I was wondering how would I be able to display let's say the whole globe but shift the grid 180 so that great britain would be in the center of the map rather than being cut at the edge.

[Matplotlib-users] Making an Axis Label like a legend
Hello again, I've got a question about axis labels, specifically y axis labels for multiple lines. What I'd ideally like to do is take something like the legends shown in the attached picture, rotate them 90 degrees counter clockwise, then stick them to the left of the Y axes to use it as a label there. I don't think there is any way to rotate the legend, but is there anything I could do to get a similar effect? Basically I'd like the legend out of the plot area and into the y axis title, but it needs to show which line is which. Having the sample line and marker in the title would be perfect, but I guess just having the words in the corresponding colour would work too. Thanks a lot!

Re: [Matplotlib-users] contourf doesn't like a rectangular grid
Hi there, I think I made a mistake with putting in a tuple in my first email, but here is the error output from the contourf that I call within a script. I use this script before with a square grid and there is no problem. Anyway, after your email, I played with the script again and I think I have a problem with reshaping the 'z' data. For some reason, the 'z' data is not shaped the same as the meshgrid. I will try and sort it out.. Many thanks for all your help!

All, I'm using Aptana (Eclipse) and pydev on a macbook pro. I'm trying to work with the following: http://matplotlib.sourceforge.net/examples/user_interfaces/fourier_demo_wx.html Now, this is a fairly complicated and interconnected piece of coding. When I am trying to learn something, I like to break it down into smaller chunks and test, which is much better than trying to type in the whole program (yes, I know I can copy and paste, but working a piece at a time is the best way for me to learn). So, can anyone recommend how to test the Param class by itself, then the SliderGroup class, etc, then put all the pieces together? Suggestions at how others work this idea would be very helpful.

[Matplotlib-users] Failure compiling MPL on Snow Leopard
I am trying to compile MPL on Snow Leopard without success. I have a fairly fresh system (10.6.2) with python.org 2.6.4 installed. I have downloaded the MPL trunk with svn. I had to make a small change to the make.osx file because there are some extra ". However I still can't get MPL to compile/install; it fails when compiling zlib. The change I made in the make.osx file is on line 11. It used to be: ARCH_FLAGS="-arch i386 -arch ppc -arch x86_64" and is now: ARCH_FLAGS=-arch i386 -arch ppc -arch x86_64 The error I get while compiling is copied below. Can anyone help me figure out what is wrong? Thanks, Jeremy x zlib-1.2.3/zutil.h Checking for gcc... Building static library libz.a version 1.2.3 with gcc. Checking for unistd.h...
