MATLAB Central Newsreader - Plot Data on US Map

Plot Data on US Map

Niraj — Tue, 22 Jan 2008 13:02:03 -0500

I have a following data:

State, Anamoly, Sales
NC, -200, 10000
...

I want to plot this in a US map as following.
The states should be shaded red or blue depending on whether
the anamoly field is negative or positive. the strength of
the color varies with the magnitude of this field.

I then want to show a circle at the center of each state.
The color of this circle will be different if the "Sales"
field is positive or negative with the size of the circle
depending on the magnitude of the sales.

I used to be able to do this very quickly in excel before
they removed the map functionality.

Can onyone help with the code. I have no experience with
plotting data on maps in Matlab.

Thanks

patch() with FaceColor

patch() or rectangle() (yes, rectangle() is used for drawing circles!)
