Line Charts

Line charts are useful for showing data over time. For example, to see the numbers of leads created each month in a report, set record count as the Y-axis and created month for the X-axis. The chart displays a line connecting the record count totals for each month. Salesforce does not plot missing (null) values.

If a missing value occurs in the middle of a data set, Salesforce displays a gap in the line.

1. Grouped Line Charts
   Use a grouped line chart when you have multiple groupings—each with one important secondary grouping representing an ordered set of data—and one value to show.
2. Cumulative Line Charts
   Use a cumulative line chart when you have one important grouping representing an ordered set of data and one value to show, summed over time.
