FlexChart allows you to enter data manually in two ways: at design-time or using code.

To enter data manually using code, you can assign different object arrays to a series using the DataSource property.

For complete information on how to load data through different object arrays, refer to Loading Data from Static Arrays.

At design-time, you can manually enter data through Series Collection Editor, which you can access by clicking the Ellipsis button next to the Series property in the Properties window.

Refer to Series Collection Editor for more details.
