A method and system to perform functions including receiving a selection of a vehicle operating condition (VOC) and multiple data parameters from a vehicle. The functions include determining that a first data parameter of the multiple data parameters indicates an occurrence of the VOC. The functions include displaying, on a display, a time-based indicator, a VOC indicator pertaining to the VOC in proximity to the time-based indicator, and a first graphical representation of a first portion of the multiple data parameters from the vehicle. The first portion of the multiple data parameters from the vehicle does not include the first data parameter. The functions further include receiving a selection of the displayed VOC indicator, and displaying, in response receiving a selection of the VOC, a second graphical representation of a second portion of the multiple data parameters. The second portion of the multiple data parameters includes the first data parameter.
