stacked column with line chart?

Hi surfengine

This is a solution.

1 - Create a simple stacked column chart with the 4 series (the 3 you want as stacked + the one you want as line)

2 - Right-click on one column on top of the part of the series that you want to be displayed as line and choose Chart Type as Line.

This gives you the chart with 3 series as stacked column and 1 series as Line.

However, it may happen that the Y-scale is not convenient to the line, like in your first example, where the line is percentage and the column is value.
If that's the case,

- right-click on the line and choose Format Data Series>Axis>Secondary Axis

This way you read the line values in a different axis that you can scale as you see fit.
