Default plotting bubble shape from contour coordinates in matlab

Hi,

I am running some multiphase simulations in OpenFOAM and I want to plot the bubble contour using alpha = 0.5 in order to compare the bubble shape at various times in my simulation. I want to do this in Matlab by plotting various time steps on the same plot as a comparison.

I create the contour in Paraview and I save the coordinates of alpha=0.5 contour using File --> Save Data.

The problem is that when I plot the coordinates in Matlab the points are joined differently to what I see in Paraview (see attached image).
I have tried sorting the coordinates but Matlab just fills the whole shape of the bubble instead of showing only the outline.

Can someone please tell me how I can solve this problem or a better way to do this?

I have tried looking on this forum but was unable to find a solution
