QmlChartViewer.updateDisplay

Updates the display.

If a chart is assigned to a QmlChartViewer for display, the QmlChartViewer will automatically display it. If the chart is subsequently modified (eg. by drawing additional things in its dynamic layer - see BaseChart.initDynamicLayer), this method can be used to notify the QmlChartViewer that the modification has been completed so that it can update the display.
