[BUG] StatsPlots groupedbar with negative values

[rmarto]

Groupedbar does not stack bars when values are negative. Could you please help solve this issue?
Here's a simple example:
ctg = repeat(["Category 1", "Category 2"], inner = 5) nam = repeat("G" .* string.(1:5), outer = 2) groupedbar(nam, -rand(5, 2), group = ctg, bar_position = :stack)

Thanks, it seems my StatsPlots.jl was outdated. An update solved the issue.
