Origin Ver. and Service Release (Select Help-->About Origin): 9.1
Operating System:Win
Hello all,

I have two sets of data of different x and y values which are depicted as shown in the attached image.

Is it possible to get the data as corresponding y values (y1 and y2) for each certain value of x ?

The idea here is to get both y1 and y2 values for each value of x.
Thanks much

Hi Mohamed,

With the graph window active, select Gadgets menu - Verticl Cursor.

It will add a vertical line onto the graph, which can tag the y values of certain x for each plot.

See more references on:

Is it what you want?

Thanks much for your kind help.
Yes that is exactly what I need.

Can I get the data automatically rather the manual recording of it through the output icon because it will consume much time?

Thanks much

Everytime you move the cursor to a new location, you can press hotkey O to output results.

Or if you have a set of X values in column D, you can use Set column values to do the interpolation.

e.g. suppose your original data are in column A(X), B(Y), C(Y).
Add column D, E, F.
Enter x values in cells of column D.
For column E, enter the following formula in F(X) cell
col(B)(col(D))
For column F, enter the following formular in F(X) cell
col(C)(col(D))

In Origin 2015, we added interp labtalk function which can do interpolation with more options, such as spline in Set Column Values dialog.

Thanks, Snow

When you are using the Vertical Cursor and move the cursor line to an expected location, press O key on the keyboard, a new row of result will show in the Cursor workbook.

Thanks, Snow
