Hi Bob,
You cannot achieve this directly from the designer - you'll have to write some code that stacks four charts vertically and uses left / right aligned guidelines or code that has multiple y axes attached to a single plot... For an example you can check out the following example:
http://examplesaspnetchart.nevron.com/Frames/NExampleFrame.aspx?ExampleUrl=Examples/Axes/General/NRulerSizeUC.ascx
It shows how to create multiple y axes and display different series on the same plot, but scaled on different y axes. Let us know if you have any questions or meet any problems.
Best Regards,
