Outline in charts

Hi,

I’ve failed at finding the appropriate setting for drawing the outline/bounding box of a PlotOverLine filter in the line chart view.

I know how to toggle the grid, which kind of serves my purpose, but I would prefer the outline draw in the same thickness as the axes (as in matplotlib default plotting style). I have found a workaround by adding some ghost lines (as in not actually drawn) in the top and right axes and then removing the axis labels, but there should be a more direct way, IMO.

Is there a toggle I’m missing or should this be a feature request?

Thanks in advance,

Guillermo
