Description:

If you have many series for the PIE chart those smaller ones are combined to the last group that is called "other".
When you upload a file before you click to save it that "other" label is visible:

But once you click "Create Chart" that label gets disappeared in both Library and front-end:

I tried rolling back many versions back and this issue is always present so doesn't look like a regression issue.

How to reproduce:

You can use this file to create a PIE chart - WW-Pie-priority-states-2.csv

1. Create a PIE chart and upload the file provided (as it has multiple series)
2. Check that after you import data the "Other" label that combines smaller values is present
3. Click to Save Chart - you'll see that label is not rendered.

Expected behaviour:

"Other" label should be present

Current behaviour:

Label not present.
