[Matplotlib-users] how to display figure from a GUI app?

I have a GTK app which runs its matplotlib stuff in a separate thread. If I call pylab.show() at the end of building the plot the first time it displays, then after that I have to destroy the window before it will think about plotting something else, and it never does (it pretends to - my log mess

[Matplotlib-users] strip chart: thanks for you help

I finished my strip chart widget thanks to help from Tony S Yu, Benjamin Root and others here. It supports multiple subplots and multiple lines/subplot. Here's a copy if anyone is interested: I plan to add it to the RO python p

[Matplotlib-users] Making room for tick labels

Not to pile on the "auto-adjust to make labels fit" bandwagon, but I've been following the FAQ on adjusting the subplot locations to make room for too-long tick labels: http://matplotlib.sourceforge.net/faq/howto_faq.html#automatically-make-room-for-tick-labels and have found that the FAQ cod

Re: [Matplotlib-users] How to find out the extend of the actual image in pixels

If you're just looking for the dimensions of the overall figure in pixels, you can easily access them through other means. E.g: import matplotlib.pyplot as plt fig = plt.figure() _, _, width, height = fig.bbox.extents # <- Extent of the figure in pixels fig.savefig('temp.png', dpi=fig.dpi) # <- Be

[Matplotlib-users] Missing Toolbar Button inside Wx Application

Hi all, if I plot an normal figure the toolbar contains an button (looks like a checkbox), which can be used to edit the lines and axes parameters. But when I embed such a figure in an Wx application, this specfic button is missing. Is there a way around it? Thanks for your help, Sebi Parts of

Re: [Matplotlib-users] How to find out the extend of the actual image in pixels

This is interesting. It seems that the event.x, event.y values are for the entire figure area rather than limited to the image. Anyone know how to get the image values instead? Also, I wonder how one might get the values of the pixels (i.e. image value) at the pixels that you click on. One more

[Matplotlib-users] How to find out the extend of the actual image in pixels

Hi, I would like to know how to find out the extend of the actual image in a plot, in units of pixels. As example I have attached a plot which is essentially empty. The lower left corner is indicated by a red dot - what pixel position does this location have? When opening this image in e.g. kview

[Matplotlib-users] change tick label font size

I'm using matplotlib 0.9, is there a best way to do this: for labeltick in ax.xaxis.get_majorticklabels() + ax.yaxis.get_majorticklabels(): labeltick.set_fontsize(15) I can't do: ax.tick_params(labelsize=15) as here: http://matplotlib.sourceforge.net/api/axes_api.html?highlight=tick
