Hello,
Would anybody mind having a quick look at this code and advising me of
how to:
a) Plot another y axis on the right hand side with a different scale on it
b) Label the x and y axes
c) label the lines on the graph.
I have been trying commands such as inputspec->GetAxis()->SetTitle()
axis1->SetName etc
Many thanks in advance.
Here is the code:
{
gROOT->Reset(); // reset global variables
gStyle->SetCanvasColor(10);
gStyle->SetTitleColor(10);
gStyle->SetFrameFillColor(10);
gStyle->SetOptStat(0);
ifstream data; // declare a file to input from
data.open("led1.data"); // open file containing values
const Int_t n = 100; // number of points to be plotted
Int_t in = 0;
Float_t x[n], y1[n], y2[n];
Float_t x1;
char line[1024];
while (data >> x1)
{
x[in] = x1;
data >> y1[in];
data >> y2[in];
in++;
}
for (Int_t i=0; i<in; i++)
{
cout << x[i] << " " << y1[i] << " " << y2[i] << endl;
}
TGraph *inputSpec = new TGraph(in, x, y1);
TGraph *inputSpec2 = new TGraph(in, x, y2);
inputSpec->SetTitle("Intensity of LED 1");
TCanvas *c1 = new TCanvas("c1", "Intensity of LED 1",0, 0, 800, 600);
c1->SetLogy();
inputSpec->Draw("AC");
inputSpec2->Draw("CP");
}
