jqplot bars not lining up with grid

Question

Does anyone know why some of the bars are not lining up in this jqplot bar graph? You can find this at http://www.vonlay.com/jollymeter/app

Answer 1

I figured it out, my y-axis format string was masking the fact that the grid lines weren't on integer values.

yaxis: { min: 0, tickOptions: { formatString: "%d" } }

This topic talks about what I was trying to achieve and the issue that I had unintentionally caused.
