[Solved]-Using an ordinal scale ('d3.scale.ordinal') for the x-axis in a bar chart-d3.js

Two things:

1. Pass dc.units.ordinal as the parameter to .xUnits().
2. Pass an ordinal scale function to .x().

Here's what I mean:

.x(d3.scale.ordinal().domain(["", "a", "b", "c"])) // Need empty val to offset first value
.xUnits(dc.units.ordinal) // Tell dc.js that we're using an ordinal x-axis

See this JSFiddle: http://jsfiddle.net/reblace/tbamW/156/

For some reason, I couldn't get renderHorizontalGridLines() or renderVerticalGridLines() to work, but the rest is good.
