MegaVision Network Management System - Manual (Page 23)

In addition to Line and Speedometer Graphs, MegaVision also supports bar graphs. You can
display data from any counter with bars. You can add data from a counter to an existing bar

of two or more values. The basic rules for configuring bar graphs are the same as for line
graphs.
