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

I fail to see what this would look like, could you share an illustration ?

Hi,
I want exactly the opposite of what [this user](https://stackoverflow.com/questions/51268315/how-to-avoid-the-matplotlib-bounding-box) was trying to accomplish with matplotlib, i.e., matplotlib default bounding box style.
Hope that clears it up!

Like that ?
Its a bit hacky though, in short:
- Show another variable you dont need at all
- Set “Chart Axes” to “TopRight”
- Set opacity to zero
- Check TopAxisCustomLabels
- Check RightAxisCustomLabels
Sadly the variables appears in the legend, I did not find a way to hide it.
What you are asking for should be very easy to add to ParaView properly though.

Yeah, exactly like that. That’s kind of the workaround (yours is a bit more direct, though, so thanks!) I was trying to describe, but yeah, it feels hackish. I think a proper toggle to achieve that could be a nice addition.
Should I submit a feature request somewhere else?

Thanks!
BTW, for future reference and completeness of the workaround, you can hide the variable in the legend by using an empty label.
