In DataUtilities/parseTextData
there are 3 places where series.add is done, but only one of those places does a check against a value <0 (which should add in a null)
My fix was to duplicate the <0 checking logic the other 2 cases.
The problem showed up when parsing a datastring like this:
t:1,2,3,4,-1
or
t:1,2,3,4|-1,4,5,6
a -1 in the middle of a series was fine, but at then end or immediately after a "|" would put a -1 in the dataseries, not a null.
I can include a "diff" if this is not clear.
Thanks
