#50 Double.NaN in AreaChart

[Anonymous]

Putting Double.NaN into the data-array for an AreaChart
and attempting to render it with JPEGEncoder13.encode
causes an error (detailed error message follows).
Double.NaN works for other Chart-Types. I believe, the
area at a NaN x-value should be empty, it should end at
the previous x-value and start again at the next
x-value similar to the start at the first x-value.

Detailed error message:
Still inside at end of active edge list!
