It looks like the lines might already be present in the image. If so then see https://www.mathworks.com/matlabcentral/answers/334249-manually-enter-legend-details#answer_262225

Looks like you've figured out how to plot the constellations from coordinates, so now you just need to put up the legend/labels. Did you try the legend() function? Next choice would be to manually place text there with the text() function.
