Analog input voltage "need invert"

[nevaeh speed]

when using the wizard it won't allow me to invert the voltage readings. Basically I have .35 volts for a value of 100 and 1.79 volts for a value of 0. But nothing seems to work. This is just an example. Is there a way to manually input the curve like a plot/graph? Or is there a way to fix this?

This would be a nice feature on all analog inputs.

Custom curve already exists........

You are right, but only one of them that I know of for analog inputs. And I'm already using that for oil temperature. So is there another?
