series.name is undefined on custom pie chart legend items

[Brady]

I created a custom legend visual for some column charts we are using. When I tried to apply the same visual to a pie chart the series name is undefined. I see there is a e.options.series.data[] property but I have no way to figure out what index I am currently on. How do you create a custom legend item for a pie chart?

I created an example of the issue. Line 56.

Hello,

The series.name will be undefined because the pie chart has a single series and a name is not set in the options. The text for the corresponding item would be the category from the point data which can be found from the series data and the argument pointIndex field:

function drawLegendItem(e) {
    var seriesName = e.series.data[e.pointIndex].name;

That works perfect. I was looking for a property like that but I must have completely overlooked it. Thanks.

That's the answer! Took a little digging, but I'm happy to see it work. Here's a plunkr for anyone wanting to see it in action :: https://plnkr.co/edit/6RWPIWHyVH8GdIUw1Xpk?p=preview
