Identifying a specific point on both axis

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!
 
Do you know the X and Y and just want to illustrate the relationship, or are
you trying to determine one from the other? If it's the former, add a new
series with a single X,Y point, then add negative X and Y error bars with
error bar values of 100%. Then hide the point if you want by double clicking
on it and choosing No Markers from the Patterns tab.

Thank you Jon for you help. In fact, I only have the y value. I tried
what you said for known values and it works great.
Thank you again and if you have a solution for the other case, it would
be appreciated too!

Just see Tushar Mehta reply, will try this too!
Thanks a lot!
