In Excel I created a graph which combines a column chart with a stacked column chart. People liked the result. So I tried to do the same in Crystal Reports. Here is my idea:
To start with I chose a simple Stacked bar chart. I chose the data like this:
Once the graph was created I chose Chart Options -> Axis:
There I checked Dual Axes.
In the next tab, Multi-Axes:
Here I separated the columns over the two Y-axes.
In the tab, Data labels:
Here I checked Show data labels and as Labels location: Center
The colors I adjusted through Format series risers.
