Exporting Tree Image

DancingSheep

Hello,

I have a process that in the end results in a big decision tree. I'd like to export this picture to be printed on an A4 paper, but the "Save Image" function of RapidMiner just prints whatever part of the tree is visualized at the moment and not the whole.

How do I save the full picture at a nice resolution?

Hi,

you can do that with the reporting extension. Just play around with the settings until you're satisfied.
I created an example process:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<process version="5.1.008">
  <context>
    <input/>
    <output/>
    <macros/>
