How do you plot multiple polygons (i.e. states) according to their respective, individual value (e.g. population density)? The final product should be a patched U.S. with states colored according to their respective values. I have latitude, longitude, and density values and I've tried patch, fill, and imagesc commands, but to no avail.

Hi Claire, could you possibly share some more details about what you've tried already? How are you using the commands you mentioned, and are you running into errors using them or are they just not returning the results you expect?

Hi Claire,

What you are describing is known as a choropleth map. If you have access to the Mapping Toolbox, you can try following the example below to help you get started.
