Hi, Im trying to show some data in a stacked column style, say total tests and failed tests per day. Then I want to add some data in the form of a line, say total number of staff.

I can see how to do a Stacked Column chart or a line one and can in fact see a custom one where you have the two styles. But I cant figure out how to tell it which data to put in the Stacked Column style and which to put in the Line style.

Can anyone help. Thanks.
