Subject: Finding boundary lines for set of points

Hi All,

I have a large set of points around 5000. When I plot the figure it appears to have 4 different regions. I know what the points are for all the regions. My question is the following:

Can I somehow only plot the boundary of the regions and basically fill the region?

Thanks in advance,
