how to probe value in 1D line plot in comsol

[FEAppp]

Hello,

I want to know how to probe the value in the 1D plot in comsol. As for the 3D/2D plot, I can just click evaluation 3D anywhere in the figure and it will return me a value at that location (shown in the figure).
How could I probe value in the 1D plot anywhere by clicking the location in the curve. for example, point A and point B?
Thanks a lot.

I'm afraid that the only option is to export this data in spreadsheet format and analyze it using different software.
