I spent just about enough time on this one. Now I need some help.

I need to calculate tic mark values for a y axis of an x,y graph given Min/Max Values.

The Tic Mark values should be a power of 10.

Example #1: Given a MinVal of -12.56 and a Max Value of 4567 the MinTic Mark will be -1000 and the MaxTic Mark is 5000.

Example #2: MinVal -4567 MaxVal 7.7 -> MinTic Mark = -5000 and MaxTic Mark = 1000

Example #3: MinVal -.756 MaxVal .789 -> MinTic -1 MaxTic 1.

The Min/Max Values may be anything in the range of doubles.

Thank You.

James
