Hi - I am creating bar and stacked bar charts in Gruff, but the problem  
I am having is that zero data is showing up as a thin bar. (It also  
seems to be that way in examples I have seen online where a zero value  
still shows as a thin bar or slice)

It’s not a major issue to see a thin sliver on a plain bar chart, but on  
my stacked bar chart if I have more than one zero value in a particular  
set then it adds beneath the x-axis.

If I am stacking many sets of data with many zero values I get a big  
block at the base of each bar beneath the axis

Ideally I would like to not display any bar for a zero value.

Is there some setting I am missing?

Thanks - david
