Plotting Coordinates for Specific Condition (Heat Transfer)

Is it possible to plot a graph of x,y coordinates for a specific temperature condition in COMSOL?

I am taking a slice, similar to the one attached, out of a 3D model and looking to create a graph of the position coordinates for one tempearature. From the picture, the goal would to have the graph look like a parabola.

I found that exporting the data and using python to get the coordinates wasn't sufficient since there wasn't enough data points in the temperature range I wanted.

Thanks
