Unable to invert bars in BarChartFace

[Tassadaar]

Hello! I am trying to make a bar chart with positive and negative values, where the negative ones are shown as inverted bars (below the x-axis). Is BarChartFace the right choice for my purpose, or should I consider alternatives? Thanks!

I currently have this but x-axis seems to be one and the same with the min value:

values = [0.1, -0.1, 0.2, -0.2, 0.3, -0.3]
labels = ["A", "C", "D", "E", "F", "G"]

face = BarChartFace(
                  values=values,
                  labels=labels,
                  colors=["blue", "blue", "blue", "blue", "blue", "blue"],
                  min_value=-0.5,
                  max_value=0.5
         )
