Put this into a file called CircularLinegraph.eps. You can then open it in any editor that understand EPS like illustrator, ghostscript, TEX, etc.

The demodata is here in the beginning for show. Ib reality all you need to do is dump your data at the end of file

[1 2 3 4 ... space separated numeric entries here ... n-1 n] drawCircChart


As many as you like.



Image 1: this is what the demo data set looks like. to add more echoes add more drawCircChart calls.

Protip If you link this file into your document, for example in illustrator, then you can edit the data afterwards and your document updates. Best of both worlds. And yes its CMYK data.
