Stacked area charts

[kremerl]

Hi there,

I love your work, thank you so much for that!

A way to improve it would be to be able to be able to make stacked area charts.

For example: have 3 categorical variables: restaurants, bars, coffeeshops and a binary variable (still open / closed)

And be able to create an area chart for each categorical variable (that is red for closed and green for still open).

You are able to do that already, but I believe you can't "stack" them on top of each other, hence visibility is not as good as it could be.

Cheers,

Louis
