Methods

Use the dxPieChart registered method to access the PieChart widget, as demonstrated in the code below.

var pieChart = $("#pieChartContainer").dxPieChart("instance");

The beginUpdate() and endUpdate() methods prevent the widget from excessive updates when you are changing multiple widget settings at once. After the beginUpdate() method is called, the widget does not update its UI until the endUpdate() method is called.

To learn about series selection, refer to the Selection Handling help section.

Normally, the widget will redraw itself automatically after the browser window is resized. But on rare occasions, you may need to request the redrawing, e.g., after the widget container is resized. For this purpose, call the render() method.

You can call the render method without parameters after the size or visibility of the widget container is changed. Alternatively, call the render method passing an object as the parameter. This object must contain the force field set to 'true'. In addition, you can use this object to specify whether or not to perform animation on redrawing with the animate field, and whether or not to redraw the widget in an asynchronous mode with the asyncSeriesRendering field.

The following code sample illustrates the example of the object that can be passed to the render method.

var renderOptions = {
    force: true, // forces redrawing
    animate: false, // redraws the widget without animation
    asyncSeriesRendering: false // redraws the widget synchronously
}

This method shows the loading indicator. To hide it, call the hideLoadingIndicator() method.
