plotTree needs improvement #10

Closed benRenard closed 4 months ago

benRenard commented 12 months ago

Main problem: nodes can overplot the way the function was coded. A quickfix was implemented in commit d00d3e4 so that all nodes can at least be seen, but it's still not very nice. The function needs to be recoded, I can see 2 options:

compute coordinates by travelling the tree upward (i.e. from terminal nodes to node 0), rather than downward as currently implemented.
try a polar plot, where node 0 would be at radius 0, level-1 nodes at radius 1 and evenly-spaced angles, etc.

plotTree has been modified in commit: 07dbb5a.

Update tree structure plot :

Plot node level by level
Assign an axis reference to plot nodes
Axis reference can move level by level depending on the number of children on the left or on the right
Plot node using point and text instead of label

Feel free to reopen the issue if necessary.
