[Matplotlib-users] Removing a data series
I did my best to search the examples, mailing list, etc. but was surprised that I didnt even find this question asked, let alone answered. My basic question: Is it possible to remove a data series from a matplotlib plot? Longer question: I'm using matplotlib to generate graph images for an interactive web site. Through the web site, the user can create a plot and add data series to it. I'd also like the user to be able to remove a data series. At the moment, I am accomplishing this by clearing the plot and replotting all the data series except of course for the one to be removed. This seems inefficient. So something like: fig = Figure() ax = fig.add_subplot(111) series1 = ax.plot(some plot parameters here) series2 = ax.plot(some plot parameters here) series3 = ax.plot(some plot parameters here) And now I want to remove series2 from the plot. Is this possible? If it is, can anyone point me to the relevant part of the user's guide/class library? Or is the best approach to clear the plot and replot 1 and 3 (and reset all the axes, legends, etc.) I apologize if this is a FAQ, but as I said, my search for it came up empty.

Coincidentally it was asked just yesterday by Andrea Gavana, but you may have missed it in your search (it may have crossed with your posting time). My basic question: Is it possible to remove a data series from a matplotlib plot? Here is a little self-contained example you can try (N==numpy, P=pylab): In [24]: x = N.arange(10) In [25]: fig = P.figure() In [26]: ax = fig.add_subplot(111) In [27]: ax.plot(x) Out[27]: [matplotlib.lines.Line2D instance at 0x427ce7ec] In [28]: ax.plot(x+10) Out[28]: [matplotlib.lines.Line2D instance at 0x427ce88c] In [29]: ax.plot(x+20) Out[29]: [matplotlib.lines.Line2D instance at 0x427ce9ac] In [30]: P.show() In [31]: ax.lines Out[31]: [matplotlib.lines.Line2D instance at 0x427ce7ec, matplotlib.lines.Line2D instance at 0x427ce88c, matplotlib.lines.Line2D instance at 0x427ce9ac] In [32]: del ax.lines[1] In [33]: P.show() This makes the middle line disappear from the plot.

[Matplotlib-users] Alpha and colorbar using contourf
When I use contourf with an alpha argument and the hot color scheme. The alpha causes the colors to come out lighter but the colorbar does not adjust accordingly. Is this a bug or do I simply need to adjust the colorbar in some manner?

No wonder I was having problems! Do you know who produced the wxPython installer package? Robin Dunn builds those himself. If so, please tell me or feel free to forward this message (edited as you see fit). I want to suggest they put links to binaries in one of: - /usr/local/bin - /Library/Frameworks/Python.../bin I think the former is the right choice if the associated wx C++ libraries (as installed by wxPython) are accessible to C++ users. They are really intended to be used specifically by wxPython. Often they are slightly different versions. I now when I've used wx for C++, I've used different libs. Otherwise if it's really a python-private sort of thing then it should probably be the latter. I think so. But there is a problem there, too. As I mentioned, you can have different versions of wxPython installed at once, so which one would put it's wx-config there? Also, /Library/Frameworks/Python.../bin is the default locations for binaries on OS-X, set by dist-utils. On other systems, it's set to /usr/local, or who knows? In that case, putting wx-config there could clash with both C++ wx installations, and wxPythons used for different versions of python -- there's just no easy way. At least this way, when you pick that wx-config, you KNOW you've got the one you want. As far as MPL is concerned, we could write a little code that would search for the default wxPython, and find wx-config there. However, the better solution is really to get rid of the compile-time dependence on wx -- that's a problem anyway. For instance, I'm not sure we should make the pythonmac binary depend on wxPython 2.7 -- that is a development version -- 2.6.3 may be a better choice.

[Matplotlib-users] x and ylabel problem when embedding in wx

lines :

a.set_xlabel('Xaxis [u.a.]')
a.set_ylabel('Yaxis [u.a.]')

labels and xlabel is hidden by the navigation toolbar.

[Matplotlib-users] x and ylabel problem when embedding in wx
Hi,
(I'm sending again because email was probably filtered?)
I have problem with xlabel and ylabel when embedding in wx. See snapshot :
http://emmanuelfavrenicolin.free.fr/Public/Divers/Snapshots1/wx_snap.png
I put a test code which is based on dynamic_demo_wx.py, adding only the 3
lines :
a.set_title('Title')
a.set_xlabel('Xaxis [u.a.]')
a.set_ylabel('Yaxis [u.a.]')
Just to add title, and label. In this case Ylabel is superposed on ytics
labels and xlabel is hidden by the navigation toolbar.
Do I need twiking and/or understand better wxpython ?
Anyone can help me?
sample code :
import matplotlib
matplotlib.use('WX')
from matplotlib.backends.backend_wx import FigureCanvasWx,\
FigureManager, NavigationToolbar2Wx
from matplotlib.figure import Figure
from matplotlib.axes import Subplot
import matplotlib.numerix as numpy
from wxPython.wx import *
TIMER_ID = wxNewId()
class PlotFigure(wxFrame):
def __init__(self):
wxFrame.__init__(self, None, -1, Test embedded wxFigure)
self.fig = Figure((6,4), 75)
self.canvas = FigureCanvasWx(self, -1, self.fig)
self.toolbar = NavigationToolbar2Wx(self.canvas)
self.toolbar.Realize()
# On Windows, default frame size behaviour is incorrect
# you don't need this under Linux
tw, th = self.toolbar.GetSizeTuple()
fw, fh = self.canvas.GetSizeTuple()
self.toolbar.SetSize(wxSize(fw, th))
# Create a figure manager to manage things
self.figmgr = FigureManager(self.canvas, 1, self)
# Now put all into a sizer
sizer = wxBoxSizer(wxVERTICAL)
# This way of adding to sizer allows resizing
sizer.Add(self.canvas, 1, wxLEFT|wxTOP|wxGROW)
# Best to allow the toolbar to resize!
sizer.Add(self.toolbar, 0, wxGROW)
self.SetSizer(sizer)
self.Fit()
EVT_TIMER(self, TIMER_ID, self.onTimer)
def init_plot_data(self):
a = self.fig.add_subplot(111)
a.set_title('Title')
a.set_xlabel('Xaxis [u.a.]')
a.set_ylabel('Yaxis [u.a.]')
self.ind = numpy.arange(60)
tmp = []
for i in range(60):
tmp.append(numpy.sin((self.ind+i)*numpy.pi/15))
self.X = numpy.array(tmp)
self.lines = a.plot(self.X[:,0],'o')
self.count = 0
def GetToolBar(self):
# You will need to override GetToolBar if you are using an
# unmanaged toolbar in your frame
return self.toolbar
def onTimer(self, evt):
self.count += 1
if self.count = 60: self.count = 0
self.lines[0].set_data(self.ind, self.X[:,self.count])
self.canvas.draw()
self.canvas.gui_repaint()
if __name__ == '__main__':
app = wxPySimpleApp()
frame = PlotFigure()
frame.init_plot_data()
# Initialise the timer - wxPython requires this to be connected to the
# receivicng event handler
t = wxTimer(frame, TIMER_ID)
t.Start(100)
frame.Show()
app.MainLoop()

John == John Hunter [EMAIL PROTECTED] writes: John It's not about wx or wxpython, it's a matplotlib issue. Let me add some color to that statement -- when I took a look at your screenshot, I realized you are using the WX backend and not the WXAgg backend. If you don't understand the difference, peruse http://matplotlib.sf.net/backends.html . WXAgg may have the same problem (and the same solution from my last post) but will give you more consistent rendering and layout. JDH - Using Tomcat but need to do more?
