MATLAB: Creating a “circular wheel” plot in Matlab

Question

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!

Answer 1

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.
