Greyscale Bar Graph Upgrade

My current bar-graph visuals rely on colour, but they need to stay just as clear in pure greyscale for print and photocopy use.

I have python scripts using matplotlib that generate the current graphs. I need you to change those so that the resulting visualizations work in both colour and greyscale (you can have it export two versions, for example).

In one case (attached), this may require more in-depth editing such as changing the range of the X-Axis and/or changing the type of graph from stacked bar to stacked area. In all other cases (example attached), I suspect that fairly easy changes in coloring and/or labelling will do the trick.

Please deliver:
• the edited python scripts

I'll approve the work based on preview images in greyscale that show that my material is understandable and legible without color.
