Thanks for the response Javier,
No a line chart wouldn't work in this instance.
I'll take the custom widget approach and see how it goes.
Was hoping to stick to the one approach but I need the results now so I can sell the concept to the decision makers/money spenders.
I'm a developer so I could tell them but it'll fall on deaf ears. If I can show them the results, they'll wet themselves so that gives me 26 more trial days to force the cleaner to bring their mop.
