Hi all
I have a chart/report as the attached file.
It has two series (bar series + line series in secondary axis).
The line series (series_2) is the sum (monthly sum) of each group of bar series (see chart.pdf)
The problem is that the legend, for the second series, it does not contain a single marker how the chart.
I have also read other topic, but I have not found the right solution.

How do I delete/hide the 2? series from the legend ?
Thank you for your attention
Andrea
