Getting an error when trying to build a radar from scratch

[bpamiri]

I'm trying to build a radar and I thought I'd start with the data file that is included and remove all the individual elements to get a blank radar. This step works, I was able to produce a blank radar. But then with I try to add my first element I get an error. Is there anything else one needs to do other than changing the radarData.js file to get a new radar to work.

I have a similar issue: When I add data for the top right or bottom left quadrant with a radius of >=100, the JS fails. Maybe this is identical, I suggest to try to stick with lower radius for testing it.
For top left and bottom right, larger radius is working fine ...

Looks like you need one item of < 100 radius in a quadrant or else the radar does not display

Looks like this is a bug in the underscore.js library that is causing the error if you have a quadrant with no items in it. Replacing the 1.5.2 version of the lib included in this project with the latest 1.8.2 version available seems to resolve the problem.

I have the same kind of issue, if I go above 200 in radius the graph won't render and w got the following javascript error:
TypeError: data is undefined inside protovis-d3.2.js
ps: I have upgraded to underscore 1.8.3 too

I narrowed this down a bit - if you have an empty segment and there is a non-empty outer segment in the same quadrant, you will get the above javascript error.

I've opened up a pull request with a fix for this. In radar.js, _.groupBy doesn't take into account groups that exist. I've hacked in a fill in the blanks style fix.

I can confirm that the fix from @fffej works for me. Would be great to merge it!
