[br]Hi there

I have to maintain an old program that uses a LabTalk script to draw some charts. This script does not run correctly. Since I am a total beginner with Origin Labtalk I have the following question: My code opens 2 data-sources and is supposed to draw the data into 1 graph. When I execute my code it opens an empty graph without data.
___________________________________________________________________

%A=C:\A_Grid#2a.dat;
%B=C:\A_Grid#2b.dat;   
xn= 41;
...
window -a Data1;
for (i=1;i<=xn;i+=1) {
   worksheet -t $(i*2-1) 4;
   worksheet -n $(i*2) B$(i);
   worksheet -n $(i*2-1) A$(i);
}
window -i;
window -a Data2;
for (i=1;i<=yn;i+=1) {
   worksheet -t $(i*2-1) 4;
   worksheet -n $(i*2) B$(i);
   worksheet -n $(i*2-1) A$(i);
}
window -i;
window -a Plot;
for (i=1;i<=xn;i+=1) {
   %k=Data1_B$(i);
   set %k -x Data1_A$(i);     // without these lines it works but Why?
   layer -i %k;
}

for (i=1;i<=yn;i+=1) {
   %k=Data2_B$(i);
   set %k -x Data2_A$(i);    // without these lines it works but Why?
   layer -i %k;
}

___________________________________________________________________

When I leave out the following lines, it works.

set %k -x Data1_A$(i);

set %k -x Data2_A$(i);

Does anybody know

- what this line is supposed to do?
     - What the set-command is?
     - What -x means ?

Thanks for your help.

cdrozdowski111	Posted - 07/15/2015 : 12:27:37 PM itelly, Here is the documentation on the command: http://www.originlab.com/doc/Labtalk/Ref/Set-cmd#-x_value.3B_Associate_an_X_dataset_with_a_Y_dataset Those lines of code are attempting to change the associated X column for each of the Y columns plotted in the graph. But if it works correctly without those 2 lines, then just comment them out.
