Extended Result

Version

The Business Charts panel supports the extended result object starting from version 5.0.0.

The extended result object allows you to return:

• Configuration
• Options
• Unsubscribe function

return {
  version: 2,
  config: { notMerge: true },
  option: {
    tooltip: {
      formatter: '{a} <br/>{b} : {c}%'
    },
    series: [
      {
        name: 'Pressure',
        type: 'gauge',
        detail: {
          formatter: '{value}'
        },
        data: [
          {
            value: 50,
            name: 'SCORE'
          }
        ]
      }
    ]
  },
  unsubscribe: () => {
    console.log('unsubscribeFunction')
  }
};
