Interpolate Line Chart?

[Travis Whitton]

Hello,

Simple question. Is there a way to interpolate the lines drawn on a line chart? I've figured out how to do this with an xy-plot, but I can't set the x-axis labels appropriately on that chart. In essence, I'm looking for text based labels on the x-axis ["week 1", "week 2", "week 3"] and smooth lines for the plot. How can this be accomplished?

Thanks,

Travis

Hi Travis, it's been a long time since I've played with the Incanter (Jfree) charts, but I think what you want is a "categorical" type axis.

When I was using Incanter I spent a lot of time looking through the API:

http://www.jfree.org/jfreechart/api/javadoc/index.html

Using Clojure's ability to access methods of an object-oriented API, you can cook up anything that is defined.

I created this repository many years ago:

https://github.com/Greg-R/incanterchartcustom

Unfortunately I did not include a categorical style axis in the examples.

But you can get an idea on how to piece together a custom chart.

Greg
