Disk I/O Graph Widget

The disk I/O graph widget shows read and write rates over time.

Features

The legend displays the current reads and writes per second in bytes for each mount/disk item. The y-axis automatically scales based on shown read/write values. By default this is in a linear scale, but it can be switched to a logarithmic scale through the config file.

The displayed time range can be adjusted through either the keyboard or mouse.
