E field magnitude along a line in CST

in CST, i successfully constructed my model and got resonable results.
the E field vector plot in "2D results" also gives a desired figure.
now i want a 2-D curve showing the E magnitude along a specifical line(e.g x axis). however, the results given by the Template Based Postprocessing is quite strange.
i'm wondering if i was using the correct method.
btw, is it possible to extract the exact value of E field along a line in CST? i suppose all data is saved after calculation.
many thx!

hi there
can you post your model so that its easy to see what you want to achieve.
and someone may give you better advice
