Dear all, but specially Olivier!
I know this CONT discussion is an old one - but I just stumbled on yet another example where the CONT4 algorithm is far superior to the CONT algorithm when it comes to showing data of a 2D histogram (see images). So I would much prefer replacing CONT with CONT4 everywhere. But this still comes at a price: since CONT4 is at its core a 3D algorithm, the canvas then has this awkward 3D behaviour, which makes it impossible, for instance, to zoom into the axis.
So I have a choice: either give the user the superior CONT4 algorithm and deprive them of the zoom and other functionality, or give him/her the inferior CONT(0) algorithm while providing the full canvas functionality…
Isn’t there a way to turn CONT4 into a real 2D algorithm? Once you have the contours, you can just draw them in regular 2D? Olivier, can you perhaps reconsider this?
Many thanks in advance!!
