TScatter Class Reference

A TScatter is able to draw four variables scatter plot on a single plot.

The two first variables are the x and y position of the markers, the third is mapped on the current color map and the fourth on the marker size.

The following example demonstrates how it works:

void scatter()
{
auto canvas = new TCanvas();
canvas->SetRightMargin(0.14);
gStyle->SetPalette(kBird, 0, 0.6); // define a transparent palette
const int n = 175;
double x[n];
double y[n];
double c[n];
double s[n];
// Define four random data set
auto r = new TRandom();
for (int i=0; i<n; i++) {
x[i] = 100*r->Rndm(i);
y[i] = 200*r->Rndm(i);
c[i] = 300*r->Rndm(i);
s[i] = 400*r->Rndm(i);
}
auto scatter = new TScatter(n, x, y, c, s);
scatter->SetMarkerStyle(20);
scatter->SetTitle("Scatter plot title;X title;Y title;Z title");
scatter->GetXaxis()->SetRangeUser(20.,90.);
scatter->GetYaxis()->SetRangeUser(55.,90.);
scatter->GetZaxis()->SetRangeUser(10.,200.);
scatter->Draw("A");
}
