Display label inside Stacked bar chart

I'm trying to display the customized label inside the bar chart. No idea on how to do this.. Please开发者_高级运维 help me. Label should be displayed inside each bar

You just specify this in Series config... It's working fine for me:

  label: {
      display: 'outsideEnd',
        field: 'data1',  // field name
        orientation: 'horizontal',  //  or 'vertical'

         color: '#0000FF',
        'text-anchor': 'middle'
    },
