How to extract points from multiple plot graph??

[ptc-5640736]

Dear All,

How to Obtain tha value of X for a particular S value between S1 and S2. Y is assumed to be known.

i.e, what will be the X-Y plot for a S value between S1 & S2.

[MikeArmstrong]

You will have to interpolate between them.

A plot of this function

and if one value in the table is not correct

[RichardJ]

The Y values on your graph are not the same as the Y values in your table. If the Y values in the table are plotted against X the only difference between the plots is the intercept of the lines. In your graph it looks like the only difference is the slope of the lines (although small differences in the intercept may just not be visible).

Please provide the worksheet.

[Werner_E]

Looks like simple 2D interpolation.

You'll have to privide a worksheet.

Work please with picture. I cannot save as Prime 2:
