Doing microhardness analysis, we need to identify a specific point of
the curve. So I need to know what is the x value that would correspond
to a specific and predifined Y value of the curve.

The usual way to express this would be to have an horizontal line from
this specific Y axis value going to the curve and then going down to
the X axis.

How can I do that with Excel?

Thanks for your help!
