Origin Ver. and Service Release (Select Help-->About Origin): 8.5
Operating System:win 7 32 bit
Hi,
I have 2 separated data that comes from 2 separated machines:
1. Time1 Vs. Stress (with 250 data lines).
2. Time2 Vs. Strain (with 100 data lines).
I can plot 2 beautiful plots on the same graph of time vs strain and time vs stress.
But how can I correlate and plot stress vs strain although they are not connected together? (I mean they have the same time values (up to 200 sec) but not the same time spaced).
Thanks

Carmi,
Interpolate Strain to the same time-values as Stress.
1. Assuming a single worksheet, and cols A-D are respectively, "Time1", "Stress", "Time2", and "Strain", make sure the cols are designated as XYXY.
2. Add a new column. Let's longname it "Strain2".
3. Then, use the "Set Column Values" dialog to generate using the formula:
Col(E)=
Col(D)(Col(A))
Then you can perform your statistical analysis.
