A customer asked this today, similar to this post I found from a few years ago. Anyone know how to change the text in the Group X labels to vertical?

I've: tried lots of things (properties, right click, double click, etc), looked via google, queried the properties, etc. Anyone know if the Graph Builder can do this, or is it a Wish List item? Script below creates a graph to get you started if you're curious. Thanks!

gb = Graph Builder(

Show Control Panel( 0 ),
Variables( X( :Gender ), Group X( :Floss ) ),
Elements( Points( X, Legend( 5 ) ) )
);
//nothing obvious shows up here:
Show properties (Report(gb)["Graph Builder",GraphBuilderGroupBox(1)]);
Report(gb)["Graph Builder",GraphBuilderGroupBox(1)] << Get Properties;
