Hello,
I have been able to make 1-D arrays of TH1D histograms using this syntax:
TH1F** xarray = new TH1F*[xcoords];
for(int x = 0; x < xcoords; x++) {
xarray[x] = new TH1F(...);
}
However, trying to extend this to 2D does not work. How do you declare the pointers for a 2D array? I know there is something wrong with the first line, but I am not sure how to fix it.
TH1F** xyarray = new TH1F*[xcoords][ycoords];
for(int x = 0; x < xcoords; x++) {
for(int y = 0; y < ycoords; y++) {
xarray[x][y] = new TH1F(...);
}
}
