I have a TTree tree
with std::string
branch modeFlag
. Suppose I want to draw data in this tree corresponding to some special modeFlag
, for example, "A"
. The following code is not working:
tree->Draw("floatBranch", " modeFlag == "A" ");
It causes error
Error: String literal syntax error (tmpfile):1:
Error: String literal syntax error (tmpfile):1:
*** Interpreter error recovered ***
How to construct the cut corresponding to std::string
branch in Draw()
option?
