Hi Swagato,
Sorry, my answer was wrong.
The text size in the stats box is a function of the size
of the box and of the number of lines in the box.
You can set the width/height of the box via TStyle->SetStatW/H
The font size will be by default automatically adjusted.
Making the height bigger will not increase necessarily
the text size. The paint algorithm avoid overlaps between
the names on the left and the values on the right.
You may have to increase the width to increase the text size.
