[Matplotlib-users] grouped barchart categories

[Sivaram N. <nsi...@gm...>]

I'd appreciate some pointers on how to get a barchart of the following
--8<---------------cut here---------------start------------->8---
date|name|empid|app|subapp|hours
20140101|A|0001|IIC|I1|2.5
20140101|A|0001|IIC|I2|3
20140101|A|0001|IIC|I3|4
20140101|A|0001|CAR|C1|2.5
20140101|A|0001|CAR|C2|3
20140101|A|0001|CAR|C3|2
20140101|A|0001|CAR|C4|2
--8<---------------cut here---------------end--------------->8---

I've got the above in a panda dataframe df and I'd like to plot them
as 

blue: 3 bars of IIC (I1-I3) of the hours, bar labelled with subapp and
hours on top of the bar

red: 4 bars of CAR (C1-C5) of the hours, bar labelled with subapp and
hours on top of the bar

on the y axis with the date on the x axis.
