Is your feature request related to a problem? Please describe.
I am trying to create a bar chart with daily energy forecasted solar generation versus actual solar generation. I managed to get either one bar besides the other or one in top of the other but not the two overlapped.

Describe the solution you'd like
I would like to see the Forecasted energy generation, let's say in yellow in the back and the actual generation in blue in the front of the yellow bar to see at a glance one versus the other. if the actual generation goes above the forecasted then the actual generation moves to to the back and the forecasted one goes to the front , in such a way that you can see at a glance the difference and the current value all in one chart. Please see it attached the two situations' preferred view.
