Re: [Matplotlib-users] imshow for .png- low resultion

Hi Asma,

I am trying to merge a heat map(matplotlib) with a tree(.png), but the 
.png does not plot as needed or for that matter cannot be seen easily. 
Here is my code:

####### CODE
 [....]
   img = ht_ax.imshow(data, cmap=cmap, 
interpolation='none',vmax=threshold)
   [....]

How can I make the resolution of the .png image better OR for that 
matter is there a better solution to merge these together?

I see the imshow call to plot the matrix but not the one you use to plot 
the png image. Could it be that the poor image rendering is due to a bad 
choice for the interpolation param ?

best,
Pierre
