The following programming statement worked fine to create an overlay histogram;
proc univariate data=didi;
histogram IPtotal / kernel overlay;
However, I have two questions;
1. How could I set a min and maximum for x-axis?
2. It displayed a value "c=0.79". I think it is some sort of parameter for curve. Could you please tell me what this value means?
Thank you for your help in advance.
