Displaying charts with the same scale

Discussion created by oblomovskj on Jul 26, 2012
Good afternoon,
I am trying to show graphs from 50 column's values in ArcGIS enviroment, directly on the image that I have.

Once I have the results > layer properties> simbology > charts > I use Bar option.

Now, I am asking how I can get homogeneus scales between the bars, because each layer's column values from Attribute Table has a  different shown scale.
It looks the bar's unit of lenght for every calculation is taken from #the maximum value /2# found between all the column 's values.

How could i set a common bar's unit of lenght?

Thanks in advance for helping
