How to scale pathdistance accumulative cost values in arcgis 10?

Discussion created by bonniefranklin on Sep 24, 2012
I am comparing 3 maps showing on which pathsitance has been used from the same starting location under different conditions.

The accumulative values are all 0 for low, but the high value varies.

Is there a way to make all 3 pathdistances use the same accumulative cost scale (so that the high values are the same)?
