Hello Olly,

Recently I have done Morris.Bar (unfortunately, only one serie per chart) that nicely draws a bar graph (bars can be drawn using gradients - two colors or two colors + middle color linear gradients). Unfortunately I've done it before pulling your latest updates (this means - moving Grid plotting to parent class and so on).

To allow the graph to support multiple series (e.g. as drawing bars one next to another) you will need to fix createBar and drawSeries functions.

Anyway, if you are willing to update my Morris.Bar to work nicely with your recent version, I would be glad. I really need this type of chart (so I made it) and I think many will find it useful :-)
