Some of the stuff I'm trying to make working with ROOT a marginally less painful experience.

setCustomStyle.C

void setCustomStyle()
{
    TStyle* customStyle = new TStyle("customStyle", "customStyle"); 

    customStyle->SetDrawBorder(0);
    customStyle->SetCanvasBorderMode(0);
    customStyle->SetFrameBorderMode(0);
    customStyle->SetPadBorderMode(0);

    customStyle->SetPalette(1,0); // avoid horrible default color scheme 
    customStyle->SetOptStat(0); 
    customStyle->SetOptTitle(0); 
    customStyle->SetOptDate(0); 
    customStyle->SetCanvasColor(0); 

    customStyle->SetLabelSize(0.04, "xyz"); // size of axis value font 
    customStyle->SetLabelFont(62, "xyz");

    customStyle->SetTitleSize(0.055, "xyz"); // size of axis title font 
    customStyle->SetTitleOffset(0.8, "xyz"); // size of axis title font 
    customStyle->SetTitleFont(62, "xyz"); // font option 
    gROOT->SetStyle("customStyle");
}
