Origin Ver. and Service Release (Select Help-->About Origin): 7.5 SR4
Operating System: XP
Hi, maybe this is an easy question.
In a labtalk script, one can use xof(%A) to find the X of dataset %A. This works fine when one wants to find the X value of %A in a script IF the plot is created using Origin´s standards (i.e. plot Y1 against X1, Y2 against X2, etc.).
However, in many cases it is not possible, since if for example one wants to plot Y2 against Y1 (using the Plot Setup window, for example). In this case the graph and dataset won´t match (still it is not advantageous to change the column definitions, because you still have (X1,Y1) and (X2,Y2) plots).
For this particular case, xof(%A), where %A is (Y1,Y2), will return X1 and not Y1. How to proceed in this case? |

With the plot active, XOF function will get the X used by the specified Y, so
%A = xof(%(N,@D));
will set the %A variable to the X dataset used by the Nth dataplot.
e.g.
%A = xof(%(2,@D));
gets the x dataset used by the second dataplot in the active layer of the active graph window.
