Visualisation of Decision Trees

Hi,

 

I am in the process of finalising some decision tree outputs and I am noticing the edge lines are difficult to see (light grey), is there a way to edit the decision tree layout to use solid black lines and further edit other parts of the decision tree visually?

 

Cheers,

Chris

    Hi @chris92 ,

     

    You can highlight the line inthe model view for the trees. But cannot modify the color.

    Have you tried the "get decision tree path" operator from operator toolbox extension?

    You can extract decision rules in the path to better understand and explain the predictions. #noblackbox

    If you export your decision tree using Export Image and choose the filetype SVG you should be able to edit it in a reasonable graphic editing tool.
