Hai Guys.
You’ve been asked to create a new Lead trending dashboard. Rather than creating the dashboard from scratch, install a CRM adoption dashboard package from the AppExchange into your Developer Edition environment and update one of the dashboard components as specified below. (Note: While it's a best practice to always clone a dashboard before you modify it, for this example, you can go ahead and modify the dashboard directly).Install Salesforce Adoption Dashboards from the AppExchange into your Developer Edition.
Refresh the '3 - Sales & Marketing Adoption' dashboard in the 'Salesforce Adoption Dashboards' folder at least once.
In '3 - Sales & Marketing Adoption' dashboard, change the dashboard component for 'New LEAD Trend by Source' to a pie chart and set the wedges to Lead Source.
