Hi All,

How to interpolate\extrapolate X from Y by script?

For example, I need to find the x value from a curve (or worksheet) when y=5%.

I have one more general question is that how to get the join data point between two curves.

Could anyone help me out?

Thank you in advance.

Steve

Maybe this link can help.

Basically, you need a XYRange, and assign the column you want to interpolate as Y. You can see more interpolation examples in that page.

Thanks
Larry
