Custom zero point on bar charts

[tomeverin]

Hi there,

I am trying to chart percentiles (0-100%) with a horizontal bar chart.

I'd like to be able to set 50% as the mid point (e.g. Y=50), so that percentiles below 50% will be drawn to the left of the X axis.

The following is the effect I am after (note I have put overlay labels on the bars just to indicate the input data, I'm not seeking this visual effect):

Is there a way to achieve this with axis/scale options? Could it be done by creating a custom axis?

Thanks,
Tom

This isn't possible in v2.x, but it is possible in v3 using the base option of the dataset. See https://jsfiddle.net/pfrgwmde/
