Cube.js 时间序列，不包括周末

Question

I am using mongo db BI connector and trying to render date series charts using cube.js. Is there a way to apply time dimension with a date range and considering only business days? Below are my sample cube schema and collection

cube(`Entries`, {
    sql: `SELECT * FROM db.entries`,    
    measures: {
      count: {
        type: `count`
      }
    },

    dimensions: {
      result: {
        sql: `result`,
        type: `string`
      },

      date: {
        sql: `date`,
        type: `time`
      },
    },
  });

Query:

{
     "measures": [
       "Entries.count"
      ],
      "timeDimensions": [
         {
            "dimension": "Entries.date",
            "granularity": "day"
         }
      ]
}

You can do this by introducing weekdays segment:

cube(`Entries`, {
  sql: `SELECT * FROM db.entries`,    
  measures: {
    count: {
      type: `count`
    }
  },

  dimensions: {
    result: {
      sql: `result`,
      type: `string`
    },

    date: {
      sql: `date`,
      type: `time`
    },
  },

  segments: {
    weekdays: {
      sql: `DAYOFWEEK(${date}) <> 1 AND DAYOFWEEK(${date}) <> 7`
    }
  }
});

And use it in query like:

{
   "measures": [
     "Entries.count"
   ],
   "timeDimensions": [
       {
          "dimension": "Entries.date",
          "granularity": "day"
       }
   ],
   "segments": ["Entries.weekdays"]
}

To hide zero weekend values pass fillMissingDates: false when preparing the data:

resultSet.chartPivot({ fillMissingDates: false })
