Yes, you can do that. I presume you are using a recent version of Comsol Multiphysics.
In the model builder, right-click "Results".
Choose 1D Plot Group.
Right-click the 1D Plot Group that you just created.
Click 'Point Graph"
Choose the points you want to plot the desired quantity at, and load them into the selection box.
(It should be fairly straightforward what to do, from that stage.)

Hi Robert,
The issue is that I can only load one point. If I want to load more than one point on the same graph, saying 3 points, what should I do?

If you have more than one geometric point in your problem, you can load more than one point. Just select the second point the same way you selected the first one. I've attached a piece of a screen-shot that may make this clearer.

Thx, Robert, I agree if they are geometric points, we can load two or more than two of them. But if the points are from Cut Point 2D, it seems loading two or more than two points are not feasible. what I do now is export the data and plot them with matlab.

Then you add more point graph nodes under the same 1D plot group. Select one Cut Point 2D data set in each of them.

... if I have generated a plot group with for example 5 point graphs is there also a simple way to export them all in one spread sheet with one click?

Hi
you have two "easy" way to generate exportable data:
1) the Derived Values into a common table (or thereafter via a plot, then 2)
2) a combined plot with several sub-nodes
and then export the all,
but you must ensure, of you want all in the same export file, that the X axis at least are identical, or of same length. Else its better to export them separately
Take a look at the COMSOL videos on their main site section postprocessing

Good luck
Ivar
