creating highchart with ajax json data

Question

I\'m trying to create a simple chart in a page using mysql data retrieved using a mysql script

I don\'t understand how to integrate the ajax call with the data requi

Answer 1

I think you cannot return values from the success call instead you would need to call a function instead. So set up your function that initializes your chart, and in the ajax success call that function with the data

With your code example

function visitorData (data) {
   $('#chart1').highcharts({
    chart: {
        type: 'column'
    },
    title: {
        text: 'Average Visitors'
    },
    xAxis: {
        categories: ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']
    },
    yAxis: {
        title: {
            text: 'Number of visitors'
        }
    },
    series: data,
  });
}
$(document).ready(function() {
 $.ajax({
    url: '/visitdata',
    type: 'GET',
    async: true,
    dataType: "json",
    success: function (data) {
        visitorData(data);
    }
  });
 });

Answer 2

In your ajax success function call your visitorData function with data[1].data (since that's how your json is formatted)

    $.ajax({
        url: '/visitdata',
        type: 'GET',
        async: true,
        dataType: "json",
        success: function (data) {
            visitorData(data[1].data);

        }
    });

also, your visitorData function def is odd.

vistorData = function(data) 

or

function vistorData(data)

Answer 3

//parse json response
var chartSeriesData = [];
var chartCategory = [];

$.each(response, function() {

  if(this.name!="TOTAL" && this.no!="0") {

    var series_name = this.name;
    var series_data = this.no;

    var series = [
      series_name,
      parseFloat(series_data)
    ];
    chartSeriesData.push(series);   
  }
});

//initialize options for highchart
var options = {
  chart: {
    plotBackgroundColor: null,
    plotBorderWidth: null,
    plotShadow: false
  },
  title: {
    text: 'SalesOrder '
  },
  tooltip: {
    pointFormat: '{series.name}: <b>{point.y}</b>'
  },
  plotOptions: {
    pie: {
      allowPointSelect: true,
      cursor: 'pointer',
      center:['60%','60%'],
      size:150
      ,
      dataLabels: {
        enabled: true,
        color: '#000000',
        distance: 40,
        connectorColor: '#000000',
        format: '<b>{point.name}</b>: {point.y} '
      }
    }
  },
  series: [{
    type: 'pie',
    name: 'Browser share',
    data:chartSeriesData //load array created from json
  }]
}

//options.series[0].setData(datavaluejson);
var chart= $('#container').highcharts(options);
