[Plplot-general] Smart labels?

[AARON H. <he...@co...>]

For lack of a better term ... I'm looking for a feature that could place a text label in the viewport closest to a desired coordinate, but without intersecting any plotted data nor being clipped by the viewport bounds?  AFAICT, there is no API that does this.  I suppose its probably non-trivial.  I'm wondering though if there is some feature that could test for intersection/clipping before updating the plot so I could provide an iterative method of placement.  Any thoughts?

To understand the problem I'm trying to solve, see this post where the GM and PM labels get clipped (https://www.picotech.com/support/topic14311-120.html#p78941).  I suppose I could also let the user configure label placement, but only if there's no other practical way to automate it.

Thanks,

Aaron
