A radar chart or spider chart allows plotting of multivariate data. http://en.wikipedia.org/wiki/Radar_chart.
Completed as of Highcharts 2.3
It would be really helpful if the polar chart could also include functionality to plot a wind rose (wind direction and intensity) see: http://www.mathworks.com/matlabcentral/fileexchange/17748-windrose and more specifically http://www.mathworks.com/matlabcentral/fx_files/17748/5/wind_rose.png as an example. Thanks in advance.
Any idea why the charts no longer contain any data?

This is awesome work!
I would like to be able to create a visualization similar to: www.torre.nl/bestcity
This was a submission to The Economist Best CIty Visualization Contest
Still struggling a bit with the orientation of the X axis (the circumference), but here's something you can look at: http://jsfiddle.net/highcharts/2Y5yF/56/
Hello Torstein, is there any place where to look a sample with the polygon grid? Thanks! We couldn't wait for this feature, so thanks for starting developing it!

We are also interested in the polygon spider graphs. Our use case is similar to the one linked to by Alessandro, http://upload.wikimedia.org/wikipedia/en/2/21/Spider_Chart.jpg, where the graph makes a complete loop for the polygon.
Awesome polar chart so far!
Thanks! We've implemented the polygon and circle style for grid lines. Perhaps we need to reconsider this option to be set at a higher level, as the position of intermediate points will change.

Hi Torstein and thanks for you reply! You're right, radar charts normally have a circular shape, but can also be displayed as a polygon (see http://upload.wikimedia.org/wikipedia/en/2/21/Spider_Chart.jpg)
However, Dundas Polar Chart and Dundas Radar (or Spider) Chart (for example), are slightly different: you can see what I mean here: http://support2.dundas.com/OnlineDocumentation/winchart2005/PolarChart.html
I think would be nice to have an option to choose between the polygonal or circular shape.
Many thanks for your great work!!!
Thanks Alessandro! What specifically do you mean by radar/spider that's different from a polar chart? From the Wikipedia article on radar charts it is said that radar charts, spider charts and polar charts are synonyms.
Alessandro Rubichi commented
Thanks for this wonderful news: live example looks so great! Radar/spider chart would be also very much appreciated!
Thanks SL! Yes, it will support stacking.
Go Torstein and crew, go! This is looking great already. Will it also support series stacking when completed?
Please please please I NEED IT!!!!

If you could support this chart type that would be great
It would also be essential for our Skillmatrix :) Really a must-have! ;)
our company is a new user to Highcharts.
A Radar Chart / Polar Chart is an important feature for us.
Hope it will get implemented soon.
Here is the roadmap for Highcharts.
The radar plot is planned for the Spring of 2012.
As well as
range series type.
funnel series type.
box plot series type.
waterfall series type.
bubble series type.
color thresholds for different coloring of a graph above and below a threshold.
Really need such thing,
Hope you guys will soon begin to implement it!
