Creating a line chart
Line charts are useful to demonstrate changes in data over time. A typical use in Salesforce is to view the number of records with a particular characteristic over a period of time.
In this recipe, we will create a Visualforce page containing a line chart that displays the total number of closed cases per month for the previous 12 months.
Getting ready

- Click on the New button.
- Paste the contents of the
