How to check if colorbar exists on figure

Question

Question: Is there a way to check if a color bar already exists?

I am making many plots with a loop. The issue is that the color bar is drawn every

Answer 1

One approach is:

1. initially (prior to having any color bar drawn), set a variable

   colorBarPresent = False
   

2. in the method for drawing the color bar, check to see if it's already drawn. If not, draw it and set the colorBarPresent variable True:

   def drawColorBar():
       if colorBarPresent:
           # leave the function and don't draw the bar again
       else:
           # draw  the color bar
           colorBarPresent = True
