How do indicate a skip (missing data point) in a line chart data series

[sbrandt]

I've tried assign an empty and None within arrays passed to
chart.add_series()
But, I haven't found the syntax to indicate a data point is missing.

In need to indicate missing points on the nth series..

Such as this one (where the "_" is seen in the data encoding to cause
the skip):

I don't think there is a way to do this. I'm using chart.get_url() and
then manually replace a few things. If your range is set so the lowest
value is never encountered in the chart, you can replace 'AA' with
'__' to get a skip. This also works with the basic encoding, but is
much more fragile, so I would only do this with extended.

Once you're done, you can use urllib.urlretrieve to get the image
downloaded to a file.
