Axis tick count not updating when calling `chart.load(...)` with new column data

I have a chart generated with a set of data, but users will be able to ask for different bits of data and when that happens I am using `load` to load the new data. When this happens, there are certain cases where I need to update the number of ticks on the x-axis. Looking at the docs, I should be able to do this, but it doesn't seem to be working. I created a JSFiddle here (http://jsfiddle.net/lepolt/yhe7sg79/3/) that loads the initial data, then reloads new data and changes the tick count, but tick count is not reflected.
