I'm trying to highlight when my time series drops below 900000. The time series ends with the last few values below 900000, however, there is no filling under those values. I can email the grf file used to create the graph if that helps.
Thanks for the file. I'll fix this before the next release. In the meantime you can get around the problem by adding a point that is outside the extents you've specified and > 900,000 - for example 1/1/2010, 1000000.
