Using Charts

InterMapper displays historical information in a chart. Charts can hold an unlimited number of datasets for an unlimited time period. These data can also be written to a tab-delimited text file.

A chart is a persistent window that belongs to a particular map. All the data that is displayed in a chart must come from devices or links of that map.

You use the options available from the Chart Options menu to view and edit the parameters which control content and appearance of each chart.

You can also specify the file that logs the chart's data, and control options for creating new chart log files. For more information, see Chart Log Files.
