Donut Chart - Display zero values and negative values

[theoanca]

Question

While implementing the donut chart I noticed two issues and I would like to ask you if these cases work and did I miss something or if they can be implemented in the future.

The two cases are:

1. If the data source looks like this:
   [ { "Book": "BCC2_BOOK1", "Infl01": NaN }, { "Book": "BCC1_BOOK10", "Infl01": NaN }, { "Book": "BCC1_BOOK1", "Infl01": NaN }, { "Book": "BCC2_BOOK2", "Infl01": 0 } ] the donut chart does not display anything. I expect the donut chart to contain only one part related to the value 0.
   Something like this:
   

2. If the data source contains only one negative value the donut chart does not display anything.
   [ { "Book": "BCC2_BOOK1", "P&L": NaN }, { "Book": "BCC1_BOOK10", "P&L": NaN }, { "Book": "BCC1_BOOK1", "P&L": NaN }, { "Book": "BCC2_BOOK2", "P&L": "-393.610" } ]
   I expect the donut chart to look something like this:
   

Also, I noticed that if the data source contains only negative values, the chart does not display anything.
