I am trying to plot a point on a map. I can make the map, plot my point, and change my style of my marker just fine. But I can't change the size or the color. I would like to make it a bit larger and purple, specifically, [.6 .2 1]. Can anyone help? Please see the attachment for what I have tried so far.
Here is the original code, which works, making my point blue.
axesm('stereo','Origin',[-90 0],'MapLatLimit',[-90 -30])
geoshow(coastlat,coastlon,'DisplayType','polygon', 'FaceColor', 'white')
Thanks a bunch.
