Detailed Description

View in nbviewer Open in SWAN Candle Scaled, illustrates what scaleing does on candle and violin charts.

Please try to modify the static functions SetScaledCandle and SetScaledViolin

void candlescaled()
{
TCanvas *c1 = new TCanvas("c1","TCandle Scaled",800,600);
c1->Divide(2,2);
TRandom *rng = new TRandom();

TH2I *h3 = new TH2I("h3","GausXY",100,-5,5,20,-5,5);
float myRand1;
float myRand2;
for (int j = 0; j < 100000; j++) {
myRand1 = rng->Gaus(0,1);
myRand2 = rng->Gaus(0,1);
h1->Fill(myRand1, myRand2);
