Cannot remove hypen in Legend

[ehr13]

There is currently no way to remove the dash that appears after each series value in the Legend.

Thanks for the report and the screenshots.

That “dash” after each series value is actually part of the Legend marker, not a separate character that can be removed independently.
In this visual the legend marker is controlled by Format pane → Legend → Style (Circle / Box / Line / Styled Line).

When Styled Line is selected, the legend marker is drawn to match the series appearance on the chart (including dashed/styled stroke), so it will look like a dash in the legend as well.

As a workaround, if you don’t want that dashed marker, please switch the Legend Style to Circle or Box.
