displaying data in a sectioned annulus

Question

0 个投票

Hi Everyone,

I am working on a project of calculating various values to an annulus. I am calculating these values to 10 separate segments in this region.

My goal is to be able to create charts of the values using the annulus as the graph shape. So calculations to bin 1 would be displayed in bin 1 with a color based on its value.

Is there any way to easily do this?

Thanks,

Will

I’m not really certain what you want to do, but two possibilities are the rose and the pie functions. If worst comes to worst, you might have to create your own plot of your annulus, but that likely wouldn’t be to difficult.

I apologize for the short description before I was running out the door for an exam.

Suppose I have an annulus where I calculated the values for each box as below. Sorry for the bad drawing but all the sectors are of equal arc length.

Is there a way to generate this type of image in matlab easily maybe with color based on the values in them. This is to visualize data so I can begin to draft a model. Currently I have hundreds of annuli points but I am trying to find a quick way for me to visualize it in a way that will allow me to see the patterns as they form.

Star Strider the pie chart will not work as it normalizes data and the rose chart generates a histogram which is not exactly what I am looking for. Thank you for the suggestions.
