In the tooltip on the XYCharts, can I do math in the tooltips?

Or do I need to make a series that has the numbers I need to show, then point at that value in the tooltip?

I mean I know I can call low, high, and average functions in the tooltip.  
Can I divide one of the values by a constant?

I don't think that AM Charts support that themselves so there would be no capabilities for IA to expose to Ignition developers.

Thanks Transistor, I thought that might be the case.

I think in another project I had bound the tooltip text to backdoor the math into the tooltip.  
I think for my current project, I will probably make a hidden series to reference in the tooltip.
