For the basic usage of graphs see Working with graphs and Viewing historical data.
The charting view comprises two parts. It is the chart itself which is located in the upper part and an area containing information about the charted MBean attribute located in the lower part of the view. The information in the lower part should be self-explanatory.
Due to the fact that a MBean attribute can contain any possible data it is sometimes necessary to set a appropriate plotting type otherwise the chart can be difficult to interpret. The type can be changed in the Plot as.. menu located under the Preferences icon in the upper right corner of the view. The correct plotting type will be set automatically for many common MBean attributes.
The following table contains a description of each available plotting type.
| Type | Description |
|---|---|
| Default | The values will be plotted without any adaption. |
| Percentage values | The values are interpreted as a percentage value (1 = 100%). |
| Percentage values (Clamped) | The values are interpreted as percentage values. The range is between 0 (0%) and 1 (100%). Values outside of this range are aligned to the limits. |
| Memory | The values are interpreted as a byte count. |
| Boolean values | The values are interpreted as binary values (1 (true) or 0 (false)). |
