I use imagescnan quite a bit. However, I can't export those figures as pdf since the white patches masking the nan areas are always dropped when using export_fig. I can't seemt to find a way to keep the patches. Exporting using standard pdf export works fine in this regard, yet it's very clumsy.... that's why export_fig is always first :)
The textcolor 'xor' property does not work for me. It looks odd when rendered but when I try to save the figure as pdf, jpg or some other image format, all the text returns to black thus unreadable if the colormap has very dark values in some areas.
I've integrated the 'tight' argument in many of my functions but just saw that it is cutting off any xlabel one adds to a boxplot... no idea why xlabels of boxplots are treated entirely different than those of other plots.
I have found a temporary fix for the exporting as eps problem. When you export, do not "Save As" but instead use "Export Setup". Under "Rendering" in Properties, choose the Resolution as "Screen" (do NOT use Auto). This should keep the magnifying square where it should be.
Using with colorFreeze, this work well. However using it along with a 3d plot (surf)causes the colorbar to have a LOT of numbers all around the figure... This is a shame though since my only use is for such usage...
