Setting a default chart type
Reports look really nice when they are consistent. To this end, Administrators have the ability to set a default chart type for new measures that are added to the account.
Feature available for Professional Plan and above
Open System Settings in the control panel and click on Admin Options.
Click on Default Series & Charts.
Click on the Charts tab. Use the Default Chart Type dropdown menu. This will be the default chart for whenever anyone adds a new measure. Use the Update Chart Legends to bulk edit the location of all legends in charts across your account. Click Save.
