8 | This application shows you how to customize different visual properties of a ChartView and series. It shows | |
|
|
9 | a wheel of fortune by customizing a pie series. | |
|
|
10 | ||
|
|
11 | First we create ChartView and a couple of series. | |
|
|
12 | \snippet ../demos/qmlcustomizations/qml/qmlcustomizations/main.qml 1 | |
|
|
13 | ||
|
|
14 | The application data is generated in Component.onCompleted of the main rectangle: | |
|
|
15 | \snippet ../demos/qmlcustomizations/qml/qmlcustomizations/main.qml 2 | |
|
|
16 | ||
|
|
17 | The following customizations are done repeatedly with a timer. To highlight one of the pie slices at time | |
|
|
18 | we modify it's exploded property: | |
|
|
19 | \snippet ../demos/qmlcustomizations/qml/qmlcustomizations/main.qml 3 | |
|
|
20 | ||
|
|
21 | Then an animation using a scatter series with one data point: | |
|
|
22 | \snippet ../demos/qmlcustomizations/qml/qmlcustomizations/main.qml 4 | |
|
|
23 | ||
|
|
24 | When the wheel of fortune has stopped, we make the active slice blink by modifying it's colors. | |
