Origin Ver. and Service Release (Select Help-->About Origin): 8.5.1 SR 2 Operating System: Windows 7
I need to make a graph of two y-parameters vs. time but the time measurement is not as precise for one parameter than for the other. One is measured in 00:00:00.00 and the other in 00:00:00. How can I graph these two y-parameters with respect to time?
As long as your Time columns are actually formatted Time (and not Text) then each Time column can have any Display format you like and Origin plots correctly.
If your columns are wide enough, you can immediately tell if Origin considers the values as Text (Left justified) or Time (Right justified).
When you double-click on the column Short Name, the Format should be set to Time. If you are converting from Text or Text & Numeric to Time then you should pick the Display format that matches your text and click Apply (you should see the Time values move to the right). Once Origin 'understands' the Time values you can choose any Display format you like.
