This still doesn’t work, it draws the axis twice, like I asked about here.
On further investigation, it seems that the error isn’t being set properly:
TGraphErrors* gRatioWithErrors = (TGraphErrors*)hRatioPlot->GetLowerRefGraph();
for(int ii=0;ii<gRatioWithErrors->GetN();ii++)
{
gRatioWithErrors->SetPointError(ii,1,hRatioErrorPerPoint->GetBinContent(ii+1));
std::cout<<ii<<" "<<hRatioErrorPerPoint->GetBinContent(ii+1)<<" "<<gRatioWithErrors->GetErrorY(ii)<<std::endl;
}
