Plot over line quirks
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Entering this during the PV tutorial at SC15 ;-) I made a remark about the first point during the session, but figured the other points might also be useful to suggest.
Using the P key to place the line widget endpoints is very useful, but might be more powerful if you could pick one of the endpoint and then press P to place it. Currently it seems to pick one of the endpoints to place at random, sets it at the intersected location, and when pressing P again the other endpoint is placed.
It is hard to comprehend which widget endpoint corresponds to what axis endpoint in the plot. I.e. if you would interchange the widget endpoints the widget representation would still be visually the same, but the plot will have mirrored along the X axis
When moving a widget endpoint restrict the translation to the x/y/z axis with the x/y/z key, just like in 3D interaction (great new feature btw!)
Separate (but related) issue:
- The line widget is not visible when the view in which it is defined is not active. This makes it a bit tricky to relate the plot to the actual line set in the 3D scene (reported separately as #16875 (closed), so it can be tackled separately). Don't worry about this item, when fixing this issue, since it's a different problem.
