Vision trends and sparkline doesn't show data when launching either in windowed or full screen mode. But when I see the screen in designer it shows data. Does any body knows what could be the possible reason for this issue?  
I am using a SQLLite database connection which cis showing Status as Valid to store history data.  
I have attached images showing these symptoms.

Have you turned on legacy database permissions? (In the project security settings.) Database pens on an easy chart won't work without that permission.

Thanks a Lot Phil for your guidance on this. I had to enable Tag History under Project Properties to resolve this.
