Marker styles over 50

Hi team,

According to the TAttMarker documentation:
https://root.cern.ch/doc/master/classTAttMarker.html

I can make open marker styles like 24 with thicker lines by using the various marker styles with numbers over 50. E.g. 53, 71, … should be thicker versions of 24.

In practice this does not seem to work for me with ROOT 6.18. I just get a tiny dot. If I use marker style 24 I get the expected open circle.

Am i missing something?

Yes, this was not implemented in 6.18. See the 6.18 doc:
https://root.cern.ch/doc/v618/classTAttMarker.html#M2

To test if your ROOT version has it do:

root [0]  TMarker marker;
root [1]  marker.DisplayMarkerLineWidths();

It should display the image you see in the master version of the ref guide.
