Bars only appear at first index

The bars on my barplots aren't spread out across the whole graph, rather they are confined to the first index! enter image description here

I originally didn't want to post the code because it is a bit complicated, I was hoping that it was a bug that had been seen before!

Solution

Make sure your datasource provides values for the CPTBarPlotFieldBarLocation field in addition to CPTBarPlotFieldBarTip. It looks like you're returning the same location value for every bar index which puts the bars on top of each other.
