Plot Description:

This application presents daily comparisons of an automation station's hourly data. You pick two hours of your choice and the application will compute the difference between the two. The hours selected are for the local time zone of the station. The comparison is made between the first hour and the subsequent second hour. If the first hour is less than the second, the comparison is made on the same calendar day. If the second hour is less than the first, then the second hour is taken from the next day.

The chart displays a two dimensional histogram / heatmap underneath the plotted lines covering the period of record data.
