TGraph filled in png but NOT filled in pdf

ROOT
1

Hi,

I’m writing TCanvases with filled TGraphs into png or pdf using TGraph::Write(). But while I get the filled TGraphs in the png the pdf just does not show the filling. The simplest example I tied looks like this (*). I’m using Root 5.27.06

Is this a known feature or am I doing something wrong :frowning:…
Thanx for any help.
Roger

see the warning at the end of:

Hi,

thanx for the quick answer. But I think that this is not a gv problem. I don’t even inspect the file using gv. Or is antialias also an issue for display an acroread?

Thanx a lot,
Roger

Ok I’ll check

Can you send an running example reproducing the problem ?

Hi,

yes – but i also proceeded my self already a bit. You can find a standalone example here (*). I realized now by doing the filling interactively that when using TGraph::SetFillStyle(1.) this will not result in a filled Graph in pdf while using TGraph::SetFillStyle(1001.) (which was the outcome of the interactive Dump on the TCanvas) does. Maybe this is already pretty much of a hint. Maybe I just did somethgin wrong and 1. is not expected to give filled areas?

Thanx for your help,
Roger

yes it should be 1001
