Creating a "circular wheel" plot in Matlab?

Hi there,
I'm trying to create a plot which displays a 1-dimensional intensity curve in a circle, pretty much exactly like this: http://i.imgur.com/hFCVgkX.png.
What I'm trying to plot are DNA optical barcodes, and the species I'm dealing with happen to have circular DNA molecules. So, this circular-type plot is actually quite important. Otherwise, I could just plot them as you typically would with plot().
Any idea how I could go about this?
All the methods I've found seem to "discretize" the circles rather than allowing for continuous data.
Thanks!

Not sure what you mean by discretize. Since a everything in a digital computer is quantized, everything is discrete. Look at the example in the help for pcolor and see if that will do what you want.

Ah, true. Sorry, that was a poor choice of words. I guess what I meant was the quantization in the techniques I found was very ...large?, giving the appearance of something more like step functions than continuous curves. E.g., pie charts typically have only a small number of "slices", and I couldn't figure out how to define a gradient across them.
Anyway, I looked into pcolor, and it works beautifully. Thank you!
