Highcharts Graph displays correctly ONLY on Window Resize

In my rails application, I have a highcharts graph, and it is displayed in a modal dialog box, and when the modal dialog box loads; the graph takes up the entire box (incorrectly), but then when I resize the window; the graph resizes to its proper size, the way it is supposed to be.

This is how the graph looks when first loaded --> [Link][1] (incorrectly) This is how the graph looks after window resize --> [Link][2] (correct)

How do I get it so that the graph is properly displayed the first time it is loaded, and not after window resize?

Here is the code to that part of the page:

- player_url = URI.encode('http://'+request.host_with_port + player.url)
- player_title = "AmericanSoccerNow: #{player.title}"
- player_description = player.dek

- highchart_data = @asns.map { |asn| [asn.asn_month.try(:strftime, '%b/%y'), asn.player_rank(player)] }
- highchart_xaxis_data = @asns.collect { |asn| asn.asn_month.try(:strftime, '%b-%y')}

I really can't figure out whats going on!!!

Hey Guys I figured it out, and this is what I did to fix it:

#contain{:style => "width: 100%; height: auto; "}
    :javascript
      $(function() {
        var initializeChart = function() {
          $('#contain').highcharts({
            chart: {
                spacingLeft: 0,
                events: {
                  load: function() {
                    $(window).resize();
                  }
                }
            },
            title: {
              text: 'ASN 100 Ranking Tracker',
                style: {
                  color: 'black',
                  font: 'normal 12px "Alfa Slab One", Helvetica, Arial, sans-serif',
                }
            },
            xAxis: {
              categories: #{raw highchart_xaxis_data.to_json},
              labels: {
                lineColor: 'red',
                lineWidth: 2,
                enabled: true,
                style: {
                    color: 'black',
                    font: 'normal 10px "Arial", sans-serif',
                }
              },
            },
            yAxis: {
                reversed: true,
                opposite: true,
                gridLineColor: 'black',
                lineColor: 'black',
                lineWidth: 1,
                title: {
                  text: '',
                  style: {
                    color: 'red',
                    fontWeight: 'bold'
                  }
                },
                plotLines: [{
                  value: 0,
                  width: 1,
                  color: '#808080'
                }]
            },
            legend: {
              layout: 'vertical',
              align: 'right',
              verticalAlign: 'middle',
              borderWidth: 0
            },
            credits: {
              enabled: false,
            },
            series: [{
              showInLegend: false,
              name: "#{player.title}'s Rank",
              color: 'red',
              data: #{raw highchart_data.to_json}
            }]
          })
        };

        window.setTimeout(initializeChart, 200);
      });

Thanks let me know if you have questions

Instead of waiting arbitrarily 200ms, putting the chart initialization on window load is enough:

$(window).load(initializeChart);

When the document is ready, $('#contain').width() might not have the values you are expecting, but they should all be set by the time window loads.

This is what I did to get it to work responsively:

#contain{:style => "width: 100%; height: auto; "}
    :javascript
      $(function() {
        var initializeChart = function() {
          $('#contain').highcharts({
            chart: {
                spacingLeft: 0,
                events: {
                  load: function() {
                    $(window).resize();
                  }
                }
            },
            title: {
              text: 'ASN 100 Ranking Tracker',
                style: {
                  color: 'black',
                  font: 'normal 12px "Alfa Slab One", Helvetica, Arial, sans-serif',
                }
            },
            xAxis: {
              categories: #{raw highchart_xaxis_data.to_json},
              labels: {
                lineColor: 'red',
                lineWidth: 2,
                enabled: true,
                style: {
                    color: 'black',
                    font: 'normal 10px "Arial", sans-serif',
                }
              },
            },
            yAxis: {
                reversed: true,
                opposite: true,
                gridLineColor: 'black',
                lineColor: 'black',
                lineWidth: 1,
                title: {
                  text: '',
                  style: {
                    color: 'red',
                    fontWeight: 'bold'
                  }
                },
                plotLines: [{
                  value: 0,
                  width: 1,
                  color: '#808080'
                }]
            },
            legend: {
              layout: 'vertical',
              align: 'right',
              verticalAlign: 'middle',
              borderWidth: 0
            },
            credits: {
              enabled: false,
            },
            series: [{
              showInLegend: false,
              name: "#{player.title}'s Rank",
              color: 'red',
              data: #{raw highchart_data.to_json}
            }]
          })
        };

        window.setTimeout(initializeChart, 200);
      });

I added in a setTimeout method, and I also added in a window.resize method.

Thanks!
