Steps to reproduce: 1. In calc create a Line chart or use attachment 119527 [details] 2. Edit the chart 3. Click on one of the lines 4. Modify chart panels -> Line -> beginning or ending Arrowhead Either it should add an arrow head to the Line or the 2 arrowhead UI elements should be removed. The data series -> Line dialog box does not give any options to add arrowheads. Also I don't think it's a common use case to need arrow heads in charts, so it's probably safe to remove the 2 UI elements.
UX needed here.
No UX needed as the dialog doesnt have facilities to add arrows to the ends of a line, so the arrowhead drop downs should either be hidden or disabled.

Created attachment 119925 [details] screenshot Would be better for the arrow controls to be disabled rather than hidden, as it leaves space on the left and right.
