Hi, I am trying to do a plot where small images are used as markers at definite coordinate positions (just to make myself clear: I am trying to see how the shape of a polymer changes with different parameters, so I want little "icons" of the polymer placed at the x,y of the parameters).
Doing that with imshow() , putting images as sub-matrixes etc. seems doable. However problem is my images have a black background, and correspondingly it seems that the RGB 0,0,0 value of the matrix is shown -kinda correctly- as black (a zeros filled canvas is shown as black). I wonder: Is there a default way to tell imshow() that I want a certain colour (in this case, black) , and that colour only, to be alpha? Or do I have to manually change the matrix? Thanks! m. ------------------------------------------------------------------------------ _______________________________________________ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
