Hi, Rooters,
I've made a macro which is a simple rebin, but all the bins have different
colour.
B1(Int_t Minn, Int_t Maxx, Int_t Z){
TH2D** G = new TH2D*[Z];
TFile* File = new TFile("Root.root");
TCanvas* C = new TCanvas("C");
TH2D* K = File->Get("h3");
int Unit = (Int_t)ceil((Maxx - Minn)/Z);
char CTemp[128];
for(Int_t i = 0; i < Z; i++){
sprintf(CTemp, "G[%i]", i);
G[i] = new TH2D(CTemp, CTemp,
K->GetNbinsY(), 1, K->GetNbinsY(),
Z, 1, Z);
G[i]->SetLineColor(i + 1);
}
for(int i = 1; i <= K->GetNbinsX(); i++)
for(int j = 1; j <= K->GetNbinsY(); j++)
if(K->GetBinContent(i, j) > Minn){
int Temp = (Int_t)K->GetBinContent(i, j)/Unit;
if(Temp < Z)
G[Temp]-> Fill(j, Temp);
}
int m = G[0]->GetMaximum();
int p = 0;
for(int z = 1; z < Z; z++){
if(G[z]->GetMaximum() > m){
m = G[z]->GetMaximum();
p = z;
}
}
G[p]->Draw("LEGO1");
G[p]->GetYaxis()->SetLimits(Minn, Maxx);
for(Int_t i = 0; i < Z; i++){
G[i]->GetYaxis()->SetLimits(Minn, Maxx);
G[i]->Draw("LEGO1SAME");
}
}
The result is nice enougth, but it seams that most of the bins wouldn't be in
the "box", but always at the "other end" of the box ...
How can I make a picture like that ( "normal" LEGO with different colors )?
k.
