avoid sorting bar chart x values alphabetically


I don’t know if this has been addressed now but may I know how can i avoid bar chart from sorting my x-axis values alphabetically?? I couldn’t find it in the docs. One work around is to build the plot manually without using Bar charts altogether… but then it defeats the purpose… Is there any way I can achieve that from the Bar chart method itself ? something like (sort = False) !!!

I am using Bokeh 0.10.0 and Python 3.4.3.
