8 This application demonstrates using XmlListModel as a datasource for a Chart.
9
10 Let's define an empty ChartView first:
11 \snippet ../demos/qmlf1legends/qml/qmlf1legends/main.qml 1
12
13 Our XmlListModel uses hard-coded test data. In a real application the data source would be a timing system.
14 \snippet ../demos/qmlf1legends/qml/qmlf1legends/SpeedsXml.qml 1
15 \snippet ../demos/qmlf1legends/qml/qmlf1legends/SpeedsXml.qml 2
16 \snippet ../demos/qmlf1legends/qml/qmlf1legends/main.qml 2
17
18 The data is parsed with a timer. The line series representing each driver are created on the fly.
19 \snippet ../demos/qmlf1legends/qml/qmlf1legends/main.qml 3
