Dear experts,
I would like to draw a graph with TgraphErrors, Sometimes its more convenient to work with vectors, however TGraphErrors require a Double_t.
#include<vector>
#include<TGraphErrors>
void test() {
vector<Double_t> x,y, err_x,err_y;
//some push_back procedure here to fill in the vector
TGraphErrors *ge = new TGraphErrors(x.size(), &(x[0]), &(y[0]), 0., &(err_y[0]) );
ge->Draw("AL");
return;
}
Root complains
Error: Can't call TGraphErrors:: . . . . Possible candidates are...
(in TGraphErrors)
Is there a way to elegantly deal with this?
