Recently noticed that the colour chart in ROOT has undergone much needed improvement, the new colour wheel looks great, offering an easy way to set a large variety of colours. Very impressive.
I was wondering if the marker styles could undergo a similar overhaul. Seems that a lot of marker types are missing, such as diamonds, ovals, how about triangles that point left/right, spiky circles. I’ve attached a figure providing some example marker shapes I made quickly.
