\title Using List Models as Data Sources in QML
\brief Implements an F1 Legends Chart to demonstrate List Models as Data Sources.
\include qmlchartsgallery.qdocinc
\image examples_qmlf1legends.png {Screenshot showing driver speeds displayed as
three line charts from different people stacked on top of each other,
Fittipaldi is blue, Steward is green, and Hunt is orange}
Let's define an empty ChartView first:
\snippet qmlchartsgallery/qml/f1legends/F1Legends.qml 1
Our ListModel uses hard-coded test data. In a real application the data
source would be a timing system.
\snippet qmlchartsgallery/qml/f1legends/SpeedsList.qml 1
\dots
\snippet qmlchartsgallery/qml/f1legends/F1Legends.qml 2
The data is parsed with a timer. The line series representing each driver
are created on the fly.
