Select data to be graphed

The usage monitor graph plots the I/O data that you specify. On the graph:
The X-axis indicates time.
The Y-axis indicates the number of I/Os during the sampling period.
The legend on the right side shows the data being displayed.
The value on the Y-axis varies according to the maximum value of the statistical data appearing
in the graph. If the Y-axis value exceeds 10,000,000, the value is shown in exponential notation
(for example, 1E7 = 1×107 = 10,000,000; 2E8 = 2×108 = 200,000,000).
