Making Kymograph plot?

I'm fairly new to Comsol and have difficulties with the following: I have a time-dependent simulation that gives me a concentration as a function of space and time. The geometry and simulation is axially symmetric. I'd like to make a kymograph plot where one axis is time and the other is r, with color coding of the concentration. How can I make this happen? Thank you!

You can create an Edge 2D dataset for the edge along which you want to plot the result.

Then, add a Parametric Extrusion 1D, and set Dataset to the one you just created.

This will give you a plot with the spatial coordinate on the horizontal axis, and time on the vertical, but maybe that suffices?
