Getting dual axis on a graph in SSRS to align at 0

Question

I have a graph that has 2 values that are plotted on dual axes.  Both values can be positive or negative.  Is there a way in SSRS to align the 0 point of both axes?  Preferably, I would like to retain dynamic values for the axes.
I'm using 2008r2
Thanks for any help.

Answer 1

I figured out the issue with incrementing whole numbers, and this is the solution I used.
You will need to manually set the interval value to determine the increments you want the line showing up. In my case I wanted the primary axis to show a value every 5 and the secondary axis to show a value every 5000.
Manually setting the interval will cause the primary and secondary axes to be off again. To fix this, we will need to have the same amount of intervals on both axes. For instance, if we have 6 intervals on the primary axis we will need to have 6 intervals
on the secondary axis to keep them lined up.
I wrote custom code that will be used as expressions in the Maximum setting for both axes. The purpose of the functions will be to determine which axis will have more intervals, then calculate the maximum value needed to have the same amount of intervals.
Primary Axis Maximum Expression
=Code.FindMaxValueForPrimary(max(Fields!PrimaryField.Value), max(Fields!SecondaryField.Value))
Secondary Axis Maximum Expression
=Code.FindMaxValueForSecondary(max(Fields!PrimaryField.Value), max(Fields!SecondaryField.Value))
Custom Code
Public Function FindMaxValueForPrimary(ByVal PrimaryValue as Integer, ByVal SecondaryValue As Integer) As Integer
IF Ceiling(SecondaryValue/5000) >= Ceiling(PrimaryValue/5) Then
Return Ceiling(SecondaryValue/5000) * 5
Else
Return Ceiling(PrimaryValue/5) * 5
End If
End Function
Public Function FindMaxValueForSecondary(ByVal PrimaryValue as Integer, ByVal SecondaryValue As Integer) As Integer
IF Ceiling(SecondaryValue/5000) >= Ceiling(PrimaryValue/5) Then
Return Ceiling(SecondaryValue/5000)*5000
Else
Return Ceiling(PrimaryValue/5) * 5000
End If
End Function
