[Matplotlib-users] Contour/Contourf dynamically with slider
Hi all, I want to make a contout plot with a slider element. But I am not sure if it is possible at all and if it is possible how. The code is a mixture of two examples I found in the web. One part is the slider example of matplotlib from pylab import * N = 50 x = linspace(.0, 1.0, N) y = linspace(.0, 1.0, N) X, Y = meshgrid(x, y) Z = sin(X+16) - 2*cos(Y*5.2) c = contourf(X, Y, Z,20) colorbar() # Copied from the slider example ... not sure about the syntax axfreq = axes([0.25, 0.1, 0.65, 0.03]) sfreq = Slider(axfreq, 'Amp', 0.1, 10.0, valinit=1) def update(val): global sfreq freq = sfreq.val Z = sin(freq*X+16) - 2*cos(Y*5.2) c.set_data(Z) # Is something like that possible draw() sfreq.on_changed(update) show() I tried different stuff, but could not solve the problem. Perhaps anybody has an idea to help me. Thank you!

[Matplotlib-users] colorbar: format labels with mathtext
Hi Everyone, I would like to format the labels of a colorbar with mathtext. I have tried a lot with all the cax.formatter.___ options but unfortunately I was not able to get it working. I am plotting some Data with col = ax.pcolorfast( ... ) after this I create a colorbar with cax = fig.colorbar(col) Then I would like to change the formatter and the powerlimits with cax.formatter.format = '$%1.2f$' cax.formatter.set_powerlimits( (-4,4) ) but this does not work for me. Could you pleas help me to set the powerlimits and to format the labels of a colorbar with mathtext.

Re: [Matplotlib-users] X11 Window information for plots
You're right -- matplotlib doesn't set any of these attributes. Fixing this problem would involve adding a few lines of code to set them in each GUI backend (since each GUI toolkit, gtk, qt, tk etc. presumably handles them differently). Is this something you'd be interested in providing a patch for? Mike On 01/15/2011 03:06 PM, todd rme wrote: On X11 systems, windows generally provide information about themselves to the system. These include things like the window title, window class, window role, and window type. These allow window managers to properly handle the windows, and in some window managers (like KDE's kwin), lets you set rules for windows of certain types. As best as I can tell, by default matplotlib does not provide most of this information. It provides the window title and the window type, but it doesn't seem to provide the window class or the window role. These two properties, however, are exactly the properties someone would want to use when trying to set up rules for particular windows. This makes it impossible to set window-specific rules for the plots. Is there something in the matplotlib configuration that would let someone set these properties, and if not is there any way matplotlib could set them itself? I'm sorry if this is a common question. -Todd -- Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.

Re: [Matplotlib-users] yticks on the right and label size
On Tue, Jan 18, 2011 at 2:52 AM, g.plantagen...@runbox.com wrote:
Hi,
I have a problem with plotting two different quantities on the same plot
(overlaying two different axes).
I plot two different quantities, with different scales, on two overlapping
axes. So, I want the quantity 1 to refer to the y axis on the left (with its
ticks and labels), and quantity 2 to refer to the y axis on the right (with
its ticks and labels). I choose on which side I want the ticks with
ax.yaxis.tick_left(). Anyway, if I want then to change the label size of the
right y axis, I can't do that. I included a sample plot.
My code is something like this:
F = figure()
#First quantity
AX1 = F.add_axes(rect)
AX1.plot(x1,y1)
AX1.yaxis.tick_left() #with this I say quantity 1=left y axis
AX1.set_yticks(range(2,14,2))
AX1.set_yticklabels(range(2,14,2),size=20)
#Second quantity (with different scale)
AX2 = F.add_axes(rect,frameon=False)
AX2.plot(x2,y2)
AX2.yaxis.tick_right() #If I leave this line, I can't change the tick label
size, if I remove it, I get ticks on both sides
AX2.set_yticks(np.arange(16.8,18.8,0.4))
AX2.set_yticklabels(np.arange(16.8,18.8,0.4),size=20,position=(1.08,0))
Instead of tick_right() try:
AX2.yaxis.set_ticks_position('right')

[Matplotlib-users] help! figures closing automatically
Hello, I just upgraded my computer to windows 7. I have everything (python, wxpython, matplotlib, numpy) running now, but there is an annoying problem that when I double click on one of my scripts (simple pylab script) it runs creates a figure and plot then immediately closes... so I don't get to look at my plot. I have WXagg configured as the backend because I use matplotlib in several wxpython applications. But right now I am just using pylabin a single script to make simple plots. If I run the script from IDLE it works ok until I try to close the figure, then it locks up until I kill the IDLE. If I run in pythonwin I get the same problem as the IDLE. I'd like to just click on the script icon to run it, and when I run the script from the IDLE I'd like the figure to close when I kill it. How might I correct these issues?

[Matplotlib-users] what does numRows, numCols in subplot docs mean?
subplot(numRows, numCols, plotNum) On my local disk, the file: file:///usr/share/doc/python-matplotlib-doc/html/api/pyplot_api.html#matplotlib.pyplot.subplot contains: subplot(numRows, numCols, plotNum) where plotNum = 1 is the first plot number and increasing plotNums fill rows first. max(plotNum) == numRows * numCols and then, a little later: New subplots that overlap old will delete the old axes. However, that doc does not explain what a row or column is or what overlap means. Is there some way the figure is partitioned into rows and columns and the subplots appear in these rows and columns. If so, then how is this partition done? Does subplot(1,2,1) appear to the left and at same level as subplot(1,2,2)? What if there's subplot(1,2,1) and subplot(2,1,1). Do they overlap and if so, why?

Hi Larry, Overlap means identical parameters for subplot: In [1]: ax1 = plt.subplot(1,2,1) In [2]: ax2 = plt.subplot(1,2,2) In [3]: ax3 = plt.subplot(1,2,1) # overlap, will delete ax1 In [4]: fig = plt.gcf() In [5]: fig.axes Out[5]: [matplotlib.axes.AxesSubplot object at 0xa1b582c, matplotlib.axes.AxesSubplot object at 0xa33968c] In [6]: ax1 Out[6]: matplotlib.axes.AxesSubplot object at 0xa1b582c In [7]: ax2 Out[7]: matplotlib.axes.AxesSubplot object at 0xa33968c In [8]: ax3 Out[8]: matplotlib.axes.AxesSubplot object at 0xa1b582c In [9]: ax4 = plt.subplot(2,2,1) # also overlaps with ax3 In [10]: ax5 = plt.subplot(2,2,4) # overlaps with ax2 In [12]: fig.axes Out[12]: [matplotlib.axes.AxesSubplot object at 0xa49882c, matplotlib.axes.AxesSubplot object at 0xa5118ac] The last parameter (plotNum) for subplot determines which row and column you want based on something like the formula: row = plotNum // numCols column = plotNum % numCols Hope that helps, -- Paul Ivanov 314 address only used for lists, off-list direct email at: http://pirsquared.org | GPG/PGP key id: 0x0F3E28F7 signature.asc Description: Digital signature -- Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.

Can you try deleting ../site-packages/matplotlib, and the build/ directory for your sources of mpl1.0.1 and reinstall? Please report back either way so we get a handle on this. best, -- Paul Ivanov 314 address only used for lists, off-list direct email at: http://pirsquared.org | GPG/PGP key id: 0x0F3E28F7 signature.asc Description: Digital signature -- Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.

Re: [Matplotlib-users] X11 Window information for plots
I think I've found it. But now I need to know what the values should be. I assume the application name should be matplotlib (no quotes, with no capitalization). What about the window role? I am think either figure or plot would be good, probably the former (once again without quotes and with no capitalization). Is that reasonable? It is easy to change later, although the change should be consistent across all backends. The other issue is whether I should use the same window role for all backends, or separate roles for each backend (such as qt4 figure). Does anyone have an opinion on this? -Todd On Tue, Jan 18, 2011 at 12:54 PM, todd rme toddrme2...@gmail.com wrote: Maybe, I am not that familiar with X11 programming.

I don't see a value in distinguishing the source of the figures. Ben Root That is what I thought as well. There are three properties to deal with. First the window class. This contains two strings. One is simply the application name. The other, however, is a class. I can't find a good explanation of what this is supposed to be. For Firefox, this is Navigator for the browser and Places for the bookmarks manager. For libreoffice writer, it is VCLSalFrame.DocumentWindow. The third is the window role. For the firefox browser, this is browser. For the bookmark manager, it is organizer. So as best as I can tell, the role is a general description of the sort of application it is, such as a web browser. For matplotlib, I think this should probably be plot or graph or something along those lines. The class, on the other hand, seems to be an application-specific description of what the role is within the application. I think this should probably be figure. Does that sound reasonable? -Todd -- Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.
