饼图-进出标签

Question

Labels on the pie chart are fine to me. Labels outside of the pie chart are not, I would like to make these disappear since on Iphone or a screen that size, labels pop out of the pie chart and are out of the screen most of the time.

I did not find anything in Sencha Architect that allowed me to overide this mechanism for labels. Would someone have an idea?

You have to extend Ext.chart.series.sprite.PieSlice and override the method sliceContainsLabel :

Ext.define('yourNamespase.CustomPieSlice', {
    alias: 'sprite.custompieslice',
    extend: 'Ext.chart.series.sprite.PieSlice',

    inheritableStatics: {
        def: {
            defaults: {
                doCallout: false,
                rotateLabels: false,
                label: '',
                labelOverflowPadding: 10,
                renderer: null
            }
        }
    },

    sliceContainsLabel: function () {
        return 1;
    }
});

And so the labels will be always inside the pie chart.
