FR: Stacked and grouped barplots

[fabiangehring]

As far as I know stacked and grouped barplots (at same time) are not possible in plotly at the moment. This would be a very nice feature:

Comparable to:
Stacked and grouped

Would be nice!

• Make base of bars configurable #475
• relative barmode to stack negative values below axis #517

Here is a screenshot to demonstrate what this feature request is for:

It is possible to create a grouped-and-stacked bar chart in Plotly.js by creating each group as a subplot. It's not as simple as setting a top-level feature like 'barmode': 'stacked+grouped' but because it's more elemental it offers more options.

Here each subplot references a shared common yaxis and its own xaxis. Each xaxis gets a "domain" which here means a portion of the overall bottom axis width. Here the first group gets [0.0, 0.33], the second [0.34, 0.66] and the third [0.67, 1.0]

Merging into #3614 - which will make stack+group bars possible
