I have two questions regarding TLagend:
I am trying to center the header of my TLegend. Is this possible? From the source code of the method TLegend::SetHeader(), looks like the way to do that is to modify the first entry in the TList of fPrimitives belonging to the TLegend object, but a method to do so does not exist…
Is there a way to add a line between the header and the rest of the entries in the TLegend?
Thanks in advance,
