Flipping a Bar Chart to a Column Chart

[CarlRevell]

Is there a simple method to flip a bar chart into a column chart, nicely animated without destroying the Chart and re-creating using a slightly modified config object?

I have tried doing a chart.config.options.indexAxis ='y'; chart.update(); and chart.config.options.indexAxis ='x'; chart.update(); and sure enough the chart switches from bar to column (and vice versa), animating nicely but the axis, scales, values, gridlines, ticks are subsequently incorrect (see attachments).

The original bar chart has a linear scale (£s) along x, and a text category along y; both axis are stacked.

I have meticulously gone in and fiddled around with .type, .offset, .beginAtZero, .ticks.display, .grid.display for both x and y axis in my flip code and have come close (gridlines and ticks are not quite in the right place for the column chart) but it doesn't seem a very robust way of doing this.

Here's the starting bar chart...

Here's the column after calling chart.config.options.indexAxis ='x'; chart.update();

Here's the column chart I can get close to if I manually manipulate a bunch of options before calling chart.update() but it doesn't seem very robust to do this (maybe I've missed some too?) and the y axis grid lines aren't quite correct.
