Hi!
I'm trying to graph a (presumably) helical data set, but so far all I'm getting it points, and not a connected curve.
My code is:
#include "TH3D.h"
#include "TCanvas.h"
#include <cstdlib>
#include <stdio.h>
gROOT->Reset();
void graph() {
TPCView = new TCanvas("TPCView", "TPC View", 10, 10, 800, 800);
fHistExN023D = new TH3F("HistExN023D", "HistExN023D",
40.,-32.,32.,40.,-26.,26.,60.,-30., 30.);
FILE * graph;
graph = fopen("graph.dat", "r");
char line[16];
Float_t x, y, z;
Int_t k;
for (k=0; k<22; k++)
{
fscanf(graph, "%f %f %f", &x, &y, &z); cout << x << "," << y << "," << z << endl; fHistExN023D->Fill(x, y/10., z/10.);}
fHistExN023D->Draw("C A L P ARR");
}
Is there something I'm doing wrong? Draw("C A L P ARR") looks just like Draw().
Thanks!!!!!!!!
