[Matplotlib-users] Error with 0.99.2 when using Intel Compiler (Linux)

This may work with gcc, but with Intel Compiler, I can't force icc to understand C++.

[Matplotlib-users] Using matshow to efficiently show seqeuences of images
Hello, I'm using matshow to display a sequence of images in a QT window; i.e each time a key is pressed a new image is displayed. The performance seems somewhat sluggish (my baseline here is displaying the images using opencv). So I'm wondering if there are some well established methods for using matshow efficiently that I'm missing. Currently, I'm clearing the figure in between each call to matshow. Does this lead to expensive deallocation and reallocation of memory which could potentially be avoided by simply changing the values stored in memory?

[Matplotlib-users] markers in linestyles
Hi there, the linestyle mechanism of on-off inks is pretty flexible but still limited to dash dot combinations. It would be a nice feature if you could simply use a marker inside a linestyle instead of a dot for example. This would decouple vertices and markers and add a completely new dimension to linestyles. I have highly resolved, unregularly spaced data which look rather ugly using markers or skipped markers at vertices. Evaluating the complexity to implement this feature I got lost in the code when it comes down to the backend stuff. Which object actually calculates the arc lengths to draw the linestyles? Could that feature be feasible in MPL?

[Matplotlib-users] Label picker broken?
Picking text outside of the axes region seems to be broken in matplotlib 0.99.1
and in the latest SVN. This functionality used to work in version 0.98.3. The
example code pick_event_demo.py demonstrates the issue. The ylabel in the
red box is no longer pickable. Is there a clip_on or similar setting on the
picker that needs to be set now? Below is a simplified version of
pick_event_demo.py for reference. I also added some text to the plot to make
sure that text inside the axes region was still pickable.

[Matplotlib-users] AXES properties
Hello, I am creating a plot with multiple y-axis (up to 6) and twinx works pretty well. The problem is that there are too much wasted spaces used up by the axes. Since I have multiple axes, it cuts into the amount of space available for the plot area. I need to know how I can squeeze some spaces out of the standard axes. First thing I discovered was that I can rotate the tick labels to vertical by: plt.setp(ax.major_ticklabels, rotation=vertical) where ax is my y-axis. But then: (1) How to reduce the space between the tick and the axes label? First I tried to place the label on top but couldn't get that to work. Then I tried to change the position property of the axis label object and that have no effect. So, can somebody please tell me how I can do these 2 things? (2) How to avoid overlapping tick labels? With the way the standard x and y axis are drawn, after I do a vertical rotate of the y tick labels, the first y tick label overlaps with the last x tick label since they are both center aligned. Is there any way to change the alignment of only the first and last tick labels of an axes (while keeping the rest center aligned)?

Re: [Matplotlib-users] Assigning k key for xscaling
My initial patch is ready for your review. I tested with latest svn and customized key-mapping (from matplotlibrc) is working correctly.

I think your idea about key-mappings in the matplotlib-rc is a good option to customize keyboard short cuts and even remove short-cuts which aren't of intrest for the individual user. Furthermore the latter yields space for keyboard shortcuts, which are used in one's own program.

In addition to Sebastian's points, make sure your matplotlibrc is
specifying an interactive backend (e.g. gtkagg, tkagg, wxagg, qt4agg) if
you want the plot to appear on the screen.
