8.4 - Dynamically setting maximum value in gauge chart?

[CognosPaul]

Does anyone know if it's possible to set the maximum value of a gauge chart dynamically? Specifically I need the maximum value to always be double the first measure (target).

This is in 8.4

Thanks,
Paul

Answering my own question:

One way around this is to set the maximum value to 1. The target measure = target/(target * 2) and the actual would actual/(target * 2). The pointers would be in the correct place, but the values would be wrong. I think the ideal is to use some sort of javascript function to change it on runtime.
