You can also protect a chart by protecting the corresponding module using the REST pages. For more information, see Editing a Resource Module. When a chart is protected, a user must authenticate before viewing the chart. - Click Next.
- Enter the SQL statement in the command editor on the left. Ensure that you do
not end the SQL statement with a semicolon.The chart settings are automatically updated in the Chart Definition section on the right.
