Is it expected that using vbar_stack with zero’s in data will still leave a color artifact (glyph is not actually zero height)?
stacked graph below where zero value items still show up as a line. Regular vbar graphs do not seem to have this issue.
It is also easily reproducible by modifying the dataset in the “Stacked” example in the docs to add zeros.
The underlying HTML canvas will always draw a line if requested (e.g. the outline around a text). If you want to not have the rect outline you can set the line color to None.
Thanks,
Bryan

As suggested, setting line_color=None in vbar_stack solves the issue.
