Origin 8.0724 pro, Windows vista ultimate
I plotted two graphs from my two data set.(one x-t,one y-t) And the sets are build from two columns.(Like in the below) i'm triying to match the t columns and to plot a x-y graph from two different grahps.Could anyone help me?
x t | y t
x t | y t
x t | y t
x t | y t
x t | y t |

Hi,
I presume the t-values of the first set of data is different from the 2nd set of data? So you need to first interpolate one or the other so that the t-values are same. Then you could take the y corresponding to the same t values and plot them against one another.
So you could do this by organizing your data as in picture below (you may need to update your Origin to the SR6 patch, which is free)
So the original data is in cols A,B,C,D, organized as your t-x and t-y. Col E is made by interpolating the t-x data in cols A and B at t-values specified in col C. The tool for this is accessible from the menu item Analysis->Mathematics->Interpolate/Extrapolate Y from X. Once you do that, the data in col E corresponds to same t value as the data in col D.
You can then use Plot Setup dialog to make a plot of col D versus col E as they both now correspond to same t-values.

i still have problem with plotting. let define the problem more specific.
1.i had a data set like below(and also it's a sample part of the data)
-4.924E-5 -0.192
-4.92E-5 -0.2
-4.916E-5 -0.208
-4.912E-5 -0.208
-4.908E-5 -0.216
-4.904E-5 -0.224
-4.9E-5 -0.232
-4.896E-5 -0.24
-4.892E-5 -0.248
-4.888E-5 -0.248
-4.884E-5 -0.256
-4.88E-5 -0.264
-4.876E-5 -0.272
-4.872E-5 -0.28
-4.868E-5 -0.28
-4.864E-5 -0.288
-4.86E-5 -0.296
-4.856E-5 -0.304
-4.852E-5 -0.304
-4.848E-5 -0.312
-4.844E-5 -0.32
-4.84E-5 -0.328
-4.836E-5 -0.336
2. I made a sine fit to this data and subracted the sine fit from the data.
3. and then integrated the result
4.and now i have to plot integrated result-sine fit graph and interpolate doesn't seem to work as i found
but i should have found a hysteriss loop.
or i may make a mistake. All the suggestions will be appriciated. |
