Hello,
I know this function exists in matlab but i can't locate it's name. I'm plotting data on a map and each point across the map contains a different value (1 - 100%). I want display the values in the form of different size dots with a small dot = 1 and incrementally getting size dots larger up to 100. Which function does this? Thank you for your help in advance.

scatter() accepts a field which is the dot size

scatter(x,y,z,z); %uses z for the dot size and the color

Thanks for the speedy reply! This is a step in the write direction, i'll need to use (lat, lon). Thanks again!

If you're plotting this on a map axes (as created by AXESM) you want to use
SCATTERM.
