Grouping data weekly, monthly

Question

I have an elevator chart showing daily and weekly stock prices for a given stock. The problem is that the data array is large enough and the daily data points are “sampled” into the weekly data points, and the weekly data is checked to the monthly data points.

Is there a way to install them by the user weekly or monthly, when necessary.

Thanks in advance

Answer 1

Check out dataGrouping .
You can customize it when necessary, for example,.
Or , if you want to disable , you can set it to false, for example, the code below or here :

series: [{ type: 'candlestick', name: 'AAPL', data: arrayOfData, dataGrouping: { enabled: false } }] 

Answer 2

You can change dataGrouping.units at any time using the update() method of each series:

 //http://api.highcharts.com/highstock#plotOptions.series.dataGrouping.units var unit = 'week'; //'day' 'month' //http://api.highcharts.com/highstock#Series.update _chart.series.forEach(function(ser) { ser.update({ dataGrouping: { units: [ [unit, [1]] ] } }, false); }); _chart.redraw();

Answer 3

We tried Hack around this, where we used Highstock (Splinechart) RangeSelector , Event and DataGrouping . When we click the weekly rangeselectorButton, we will catch this event through setExtremes . The message catching the event brings it closer to the "sum". If you use two series than iterating over an object.

  events: { setExtremes: function (e) { if (e.rangeSelectorButton != undefined) { var triger = e.rangeSelectorButton; if (triger.type == 'week') { $.each(this.series, function (index, obj) { obj.options.dataGrouping.units[0] = ['week', [1]]; }); } else if (triger.type == 'day') { $.each(this.series, function (index, obj) { obj.options.dataGrouping.units[0] = ['day', [1]]; }); } } } },
