I've never seen Gchart's automatic midpointing algorithm in the doc. Here is a page that describes a little about it (but not the full algorithm)...

SAS/GRAPH(R) 9.3: Reference, Third Edition

If you want to know see the exact start & end value in the axis midpoint text (instead of seeing just the single midpoint value), you can use the 'range' option, such as ...

**gchart** data=sashelp.class;

height / range type=mean sumvar=weight;

run;

I usually pre-process my data, and calculate my own ranges for the bars (using if/else statements, or proc rank, etc), so that I know exactly what's in which bar.

Hi,

I Got cleared my doubt 95%.

Thank you for the Information, I have another Doubt regarding this -- How SAS will take number of midpoints should be given for the chart.

If we use levels or midpoints we will get how many we want, but can I know about number of default midpoints produced.
