Plotting points from a 3D model onto a 2D graph

How would I plot a 2D graph with data from a 3D model using the PDE toolbox? I have searched everywehre and cannot find an answer. Ideally, I'd like to have about 6 points going through my thermal model, showing temperature decreasing with time, and clearly display this on a 2D plot, where X = time and Y = Temperature. Below is the code used. I'd really appreciate some help as I've been trying to do this for a while now - there should be a clear way to do this as it seems like a basic thing to do.

gm = multicuboid([2 2.1 2.7 2.95 3.2 3.45 4],[2.1 2.2 2.7 2.95 3.2 3.45 4],1.55);
thermalmodel = createpde('thermal','transient');
thermalmodel.Geometry = gm
pdegplot(thermalmodel,'CellLabels','on','FaceAlpha',0.5);

figure('Position',[10,10,800,400]);
subplot(1,2,1)
pdegplot(thermalmodel,'FaceAlpha',0.25,'CellLabel','on')
title('Geometry with Cell Labels')
subplot(1,2,2)
pdegplot(thermalmodel,'FaceAlpha',0.25,'FaceLabel','on')
title('Geometry with Face Labels')
generateMesh(thermalmodel,'Hmax',1);

generateMesh(thermalmodel);

thermalresults = solve(thermalmodel,tlist);
pdeplot3D(thermalmodel,'ColorMapData',thermalresults.Temperature(:,end));

You can interpolate the temperatures at (x,y) coorinates over time and plot them. Refer to interpolateTemperatue function.
