dealing with highcharts bar chart with really long category names
===

I have a bar chart built with Highcharts that uses categories for its x-axis--really long wordy categories.  **I can't figure out a good way to make sure categories always stay on one line**. I cannot abbreviate them unless I can use a tooltip or something to show the long version upon mouse hover-over or some other intuitive user interaction.  When the categories line-wrap, it starts to look like a wall of text.  

**Any ideas for displaying long categories and data in a clean way**?  I'm willing to consider a different type of chart as long as it displays the data in a clear and nice-looking way.  I'd like to stick with Highcharts if possible.  

A picture of the problem graph, with **categories blacked out:**
