Sorry for asking such a trivial question on this forum! I am making a plot where I want to divide it into three different region ( vertically ) due to 3 different selection. I am using a macro to make this plot where I user TGraph to plot points and then join them with simple lines. Could someone suggest how to make these three different regions (let say the three regions are : (x< 3.0), (3.0 > x<4.5) and fill them with different colors??
Please find the attached macro and .eps file.
Thanks in advacne,
