Import Feature of Gantt Chart to Dashboard on Eazybi

When I import the gantt chart to dashboard, the daily/month switching button disappear.
Is there a way that I can import the daily/month button of the gantt chart from report to the dashboard?


indeed, this feature is not available from a dashboard view: similarly as other chart options in other chart types (stacked, area, etc), this feature is available only while you create the chart or access it from Analyze tab.
What would be the need to allow using this option from the dashboard?
