Hi,

I wondered how can I order the label of a stack bar chart in dash?  
Specifically, from the image shown below, how can I put the orange bar to the leftmost. Thanks!

The order of the bars should be dependent on the order that they were supplied in inside the `'data': [...]` list

@chriddyp, could this behavior (stacking relative to value) be added to stacked bar charts? This would be very helpful for a timeseries charts where the distribution of categories change over time.

At least using R plotly it seems the categories are sorted in alphabetical order starting from the center of the axis. Changing the order of the input `data.frame` has no effect.
