> Indeed: I had the case that image arrays inside an ImageGrid where shown with some white overhead area around, e.g. for an image of 100 pixels on the x-axis, the imshow resulted in an x-axis that went from -10 to 110. I was looking for a simple way to suppress that behavior and let imshow instead use the exact image extent. I believe that the plot command has such a flag, hasn't it? (I.e. to use the exact xdata range and not try to beautify the plot?

Is the 'extent' keyword what you're looking for?
