How can i get one of the bars in a clustered bar chart as a dotted line

[Anonymous]

Hi All,

I am working with a clustered bar graph. The 2nd bar shows the difference  between the 1st bar and 3rd bar.

I want to show the 2nd bar as a dotted line or at least as a line .

How can i get this done .

Thanks in advance !

Use Combo chart and in Expressions tab for the difference using Display options uncheck Bar and Check Symbol - Select Dots.
