I would like to draw a TEfficiency object through JSRoot and I am experiencing some issues.
In particular, 1D TEfficiency objects are displayed but 2D TEfficiencies instead are not: “JSROOT was unable to draw this object”.
I can see from the JSROOT documentation that the TEfficiency class is not among the supported ones, but is there a way to do this?
I think @linev can help you.
There is rudimentary support of
TEfficiency in jsroot.
And yes - only for 1D data.
If you have examples of 2D data - I could try to add support for that.
Can you upload ROOT file here and, if possible, macro which produce it?
thank you very much for your help! I attach here the ROOT file and the macro which draws and saves the 2D TEfficiency object.
Another thing I notice is that when saving the efficiency on a root file and then reopen it, the labels will be gone and the axis range will be reset. I think this is a know issue since I found this topic about it TEfficiency, x-axis text labels and scales not persistent
When we draw with JSRoot the 1D TEfficiency as a matter of fact we loose the axis labels…
macroTEfficiency.cxx (752 Bytes)
output2DTEfficiency.root (4.9 KB)
I fix several issues with
TEfficiency drawing in JSROOT and extend it to 2D case.
Now your example works with
dev version of JSROOT.
