Last item in array for custom labels being skipped.

Would you mind posting some sample code?

Sure thing! I believe I figured out what's happening, the legend will skip if a value is duplicated.

I've extracted the code into a codepen below:

If you change the values for the constant dataValues, it will add the remaining labels as long as the matching value does not exist already in the dataset. This is my first project using D3 so excuse the mess!

So what you want to do is actually pass the dataLabels into the ordinal scale for the legend. This is not really a legend problem but a scale problem. The assumption you make when you're using scales in d3 is that there are unique domain values that map to a range. Here is this fixed code: http://codepen.io/anon/pen/vXoXWV?editors=1010#0

All I did was change line 72 from dataValues to dataLabels. DataValues are values that you would pass to a scale for the scale to interpret but not to setup the scale itself. Does that make sense?
