"Actual Time" on the Graph
By default, the graph displays data in evenly distributed
intervals, corresponding to the columns of the grid below.
The Time Scale feature displays data for the entire date
range on a single graph, distributed according to the date/time stamp
on the data. (For example, a data point for January 15 will be closer
to a data point for January 16, and a data point in February will be further
away.) The data in the grid is shown between two blue lines on the graph.
