I have a function which plots data for 90 days on a chart using C3.js library. I have the start date and end date defined based on the the count variable. Is there any way in which I can group data for 90 days based on week. 1 week = 1 data point (average of 7 days). 4 weeks = 4 data points Likewise. 90 days = 12 data points and so on.

function draw__chart(model, type)

 var count = 0

 if(type == 'week')
 count = 7;
 else if (type == 'month')
 dcount = 30;
 else if (type == '3_months')
 count = 90; 
 

 $scope.end_daterange = new Date();
 $scope.end_daterange = moment($scope.end_daterange).format('MM/DD/YYYY') 

 $scope.begin_daterange = new Date($scope.end_daterange);
 $scope.begin_daterange.setDate($scope.begin_daterange.getDate()- count);
 $scope.begin_daterange = moment($scope.begin_daterange).format('MM/DD/YYYY') 


 $date_id = ["date_id"];
 $volume1 = ["volume1"];
 $volume2 = ["volume2"];


 angular.forEach(model, function(value, key) 

 //Date for Chart
 if(dateCheck($scope.begin_daterange,$scope.end_daterange,moment(value.log_date_id).format('MM/DD/YYYY'))) 
 $date_id.push(moment(value.log_date_id).format('MM/DD/YYYY'));
 $volume1.push(value.volume1);
 $volume2.push(value.volume2);

 

 );

 //Drawing Second Chart
 d3.select("#volume_graph svg").remove();

 setTimeout(function() 

 $scope.volume_id = c3.generate(
 bindto: d3.select('#volume_graph'),
 data: 
 x : 'date_id',
 columns: [
 $date_id,

 ],
 ,
 ,
 axis: 
 x: 
 type: 'category',
 tick: 
 rotate: -90,
 multiline: false
 ,
 height: 70
 ,
 y: 
 label: 
 text: 'Percentage',
 position: 'outer-middle'
 
 ,

 ,
 tooltip: 
 show: true
 
 ); 

 , 100);

};

Function to validate Date range:

function dateCheck(from,to,check) 

 var fDate,lDate,cDate;
 fDate = Date.parse(from);
 lDate = Date.parse(to);
 cDate = Date.parse(check);

 if((cDate <= lDate && cDate >= fDate)) 
 return true;
 

 return false;
 ;
