Stacked line charts with single value nothing is drawn

[#1]

Using stacked line charts and when user selects down to a single month nothing is drawn. If switch to 3D style then a line is drawn. I would expect this to work with non-3D also. See screen shots. Also, is there a way when there is a single value to force QV to draw using 0 to that value?

Hmmm, looks like a bug to me.  For a normal line chart, when you select only a single X-value, it changes from lines to symbols so that you can still see the data.  It looks like when you fill in with a color, it doesn't do that, nor does it do anything else useful, so your data disappears.  Even explicitly telling it to use symbols appears to do nothing.
