Cant compare cars in the charts
 

It doesn't show more than a single car in the charts, shouldn't it be showing all vehicles data for comparison?

When in Charts, tap the Search button at the bottom of the page, select the vehicles to display in Charts, then tap Charts at the bottom of the filter screen to show the results. Going back to the main dashboard will clear the filter criteria.

Seems like I woulnt have to do that each time I go to look at the charts, it should just remember the last setting.
