somber	Posted - 09/26/2011 : 2:17:20 PM Hello all, Here is my case. I have a plot and I want to find the y coordinate for a given x coordinate on the curve. The data reader tool is not fit for me since the space between two x coordinates is too big, and I want to find out the point in between according to the curve. Screen reader can do this but the problem is I have too many plots of the same kind and I want to do this automatically.But screen reader need people to click on the curve. Could anyone please tell me if there is fittable way to solve this kind of problem? Thank you very much for your time and consideration. Jie

Penn	Posted - 09/26/2011 : 10:27:35 PM Hi Jie, You can perform interpolation of single values through range notation on the curve. For example, there are two points (1, 1) and (2, 2) in the curve, then you can use the following script to calculate the y value for the given x=1.5. range rr = 1; // get the first curve on the graph rr(1.5) = ; // get y for 1.5 by interpolation For more details, please refer to Interpolation.
