    Graph intercept procedure

      Hi all,


      I have a graph as the one shown in the picture. The slider below the graph generates a vertical line (in black) which moves in the graph.

      Can anyone help me in finding a way to retrieve the intercept value between the black line and the green curve. Is there any function I should use?

      I thought that I could interpolate the greenline curve equation and calculate the Y value according to the X position of the black line, but maybe there is a easy way to get this without interpolating the green line point.






      This is the qv file.
