Charts present the data with the attribute value (vertical axis) over a specified time span (horizontal axis).
There are three types of charts:
Line graph: Used to plot the values of an attribute that has a unit value (such as NTP Frequency Offset, in ppm). The changes in the value are plotted in regular data intervals (bins) over time.
Area graph: Used to plot volumetric quantities, such as object counts or service load values. Area graphs are similar to line graphs, but include a light brown shading below the line. The changes in the value are plotted in regular data intervals (bins) over time.
State graph: State graphs are used to plot values that represent distinct states such as a service state that can be online, standby, or offline. State graphs are similar to line graphs, but the transition is discontinuous, that is, the value jumps from one state value to another.
