Simple example illustrating how to draw TGaxis objects in various formats.

void gaxis(){
auto c1 = new TCanvas("c1","Examples of TGaxis",10,10,700,500);
c1->Range(-10,-1,10,1);
auto axis1 = new TGaxis(-4.5,-0.2,5.5,-0.2,-6,8,510,"");
axis1->Draw();
auto axis2 = new TGaxis(-4.5,0.2,5.5,0.2,0.001,10000,510,"G");
axis2->Draw();
auto axis3 = new TGaxis(-9,-0.8,-9,0.8,-8,8,50510,"");
axis3->SetTitle("axis3");
axis3->SetTitleOffset(0.5);
axis3->Draw();
auto axis4 = new TGaxis(-7,-0.8,-7,0.8,1,10000,50510,"G");
axis4->SetTitle("axis4");
axis4->Draw();
auto axis5 = new TGaxis(-4.5,-0.6,5.5,-0.6,1.2,1.32,80506,"-+");
axis5->SetLabelSize(0.03);
axis5->SetTextFont(72);
axis5->Draw();
auto axis6 = new TGaxis(-4.5,0.5,5.5,0.5,100,900,50510,"-");
axis6->Draw();
auto axis7 = new TGaxis(-5.5,0.85,5.5,0.85,0,4.3e-6,510,"");
axis7->Draw();
auto axis8 = new TGaxis(8,-0.8,8,0.8,0,9000,50510,"+L");
axis8->Draw();
// One can make a vertical axis going top->bottom. However the two x values should be
// slightly different to avoid labels overlapping.
auto axis9 = new TGaxis(6.5,0.8,6.499,-0.8,0,90,50510,"-");
axis9->Draw();
