Visualising a 2d histogram with errors

ROOT
1

Hi,

I note that the THistPainter class includes a function, Paint2DErrors(), which presumably draws error bars on a two dimentional histogram. Can someone tell me how to activate this option? I’ve tried the obvious “hist e”, “p e”, “lego e”, etc. I’m using v4.02.04 and am actually trying to paint a TProfile2D.

Option E is enough as shown in the example here.

are you really using 4.02.04 (year 2004)

this option was introduced only sometimes in v 5

Oh yes that’s a very old ROT version (Thanks Otto I had not noticed).
I just browse the old doc versions and I see the first time it appeared was in 5.34:
