How do i plot a scatter plot of wind speed and wind direction?

How do i plot a scatter plot of wind speed and wind direction with wind speed represented by different colours indicating different wind speeds by a colorbar. I have attached an input data file and a sample output file. Kindly suggest how to do the same.

The example scatter plot image you provide also shows a third variable. It seems to show angle, distance from the center of the polar plot (which is presumably wind speed), and color. What is the third variable?

The color appears to be actual wind speed, not sure what the radial position is, either, that goes from 0-15 "somethings". But, without it, there'd be just a blob in the middle but can't think what else it might be, either. There's still something funky going on w/ the links that can't download a file as anything but text from this browser which obviously doesn't work for a .xls file so can't look at his data file unfortunately.

Did you right click and select "Save Link As..."?

Yea, I still get an ascii rendition in the saved file...

How about scatter()? You can input the color of each marker if you want. Or if you want to indicate direction, use quiver().

[dpb]

Tough w/ scatter to do the polar coordinates, though...Matlab is very limited when get out of the x-y 2D plotting.

Seems like the solution may be a two-axes plot w/ the data plotted suitably transformed via scatter over a polar axes...but the question asked above of what's actually being plotted is a good one...

There's this solution from File Exchange.

you may try quever plot to show winds speed and direction vector.
