This doesn't have the label:

var chart = new Ext.chart.PolarChart({
    animate: true,
    interactions: ['rotate'],
    colors: ["#115fa6", "#94ae0a", "#a61120", "#ff8809", "#ffd13e"],
    store: {
      fields: ['name', 'data1', 'data2', 'data3', 'data4', 'data5'],
      data: [
          {'name':'metric one', 'data1':10, 'data2':12, 'data3':14, 'data4':8, 'data5':13},
          {'name':'metric two', 'data1':7, 'data2':8, 'data3':16, 'data4':10, 'data5':3},
          {'name':'metric three', 'data1':5, 'data2':2, 'data3':14, 'data4':12, 'data5':7},
          {'name':'metric four', 'data1':2, 'data2':14, 'data3':6, 'data4':1, 'data5':23},
          {'name':'metric five', 'data1':27, 'data2':38, 'data3':36, 'data4':13, 'data5':33}
      ]
    },
    series: [{
        type: 'pie',
        xField: 'data3',
        donut: 30
    }]
});
Ext.Viewport.setLayout('fit');
Ext.Viewport.add(chart);

thanks,but this do legend show incorrectly(don't show label),i want to get the following results(image):

i read the legend.js, i found in doSetDocked method, when set docked 'top' or 'bottom', it will set layout 'hbox' and scollable 'horizontal'.so i config legend's attr as follow:

legend: {		docked: 'bottom',		layout: {pack: 'center'},		inline: 'false',		width: 300,		height: 400,		//verticalWidth: 100		scrollable: {			direction: 'vertical',			directionLock: true		}
	}

after docked, i set layout, inline and scrollable, i think this will override doSetDocked method's setting, but it didn't.
how can i do?
