Custom Report - Sparkline Option

I have a REPORT generated via “Custom Reports” that lists pageviews by the hour. It shows well in TABULAR Format - however the visualization options do not show me a BAR Diagram for ALL 24 hours. How can I add a Sparkline view to the same Visualizations ? Documentation says it is present by default - but I cannot view that option in “Change Visualization” below the report

Documentation :

Can someone help me in this ?

Hi there,

Sparkline reports are only available in Evolution reports: selection evolution in your custom report setup (you may need to create a new report)
