Thanks for the reply. The trick with clf() is that it redraws the entire
image, and hold(False), while much better, changes the axes values. Ideally
I could keep my axes setup and redraw only the bars, ala the animation
example of the plot() sine wave. Looking at that code, I'm trying something
like:
line, = bar(i + 0.25 , name_value_dict[key], color='red'), and calling
line.set_y(), but with similar issues.
Any other pointers would be greatly appreciated.
