Apparently I get no support at all with my license and can't submit a ticket? Crazy. I'm attaching the sample project here instead. Note that changing DateTimeMajorStep to 30 seconds in SensorReadingChartContentView:26, instead of 10, the labels are no longer cut off.
I can only attach images, so try this link, valid for two days: http://expirebox.com/download/2ff2f94f2c717ff7ae9924843a6cc719.html
