/*
* flot-tickrotor: flot plugin to display angled X-axis tick labels.
*
* Requires flot 0.7 or higher and a browser supporting <canvas>.
*
* To activate, just set xaxis.rotateTicks to an angle in degrees. Labels
* are rotated clockwise, so if you want the labels to angle up and to the
* right (/) you need to provide an angle > 90. The text will be flipped so
* that it is still right-side-up.
* Angles greater than or equal to 180 are ignored.
