Rendering a graph in highcharts/miso

I am trying to play with Highcharts.js and a misodatest (www.misoproject.com/dataset). All I've done is added the example script given at http://misoproject.com/dataset/examples/highstockandcsv.html.

It wouldn't run, so I edited it to what I thought should happen, I put somethings of the example into a function (). Now, I am getting no errors at all, which would be great. But I am getting no information in my page at all and I don't know why, the graph is just not rendering at all.

Here is my code:

<!DOCTYPE html>
<html>
   <head>

   </head>
   <body>
      <br>
        <div id="test" style="max-width: 800px; height: 300px; margin: 0 auto"></div>  <!-- Container for Highcharts map. -->

   </body>
      <script src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script>
      <script src="json2.js"></script>
      <script src="lodash.js"></script>
      <script src="moment.js"></script>
      <script src="underscore.deferred.js"></script>
      <script src="underscore.math.js"></script>
      <script src="http://code.highcharts.com/highcharts.js"></script>
      <script src="miso.ds.0.3.0.js"></script>


<script> 
  function chart() {

  var ds = new Miso.Dataset({
  url : "crudeoil.csv",
  delimiter : ",",
  columns : [{ name : "Year", type : "time", format : "YYYY" }]
    }); 

ds.fetch({
  success : function() {
    chart = new Highcharts.Chart({
      chart: {
        renderTo: 'test',
        type: 'column',
        marginRight: 130,
        marginBottom: 25
      },
       title: {
       text: 'World Crude Oil Barrel Production (1,000) per unit',
       x: -20 //center
      },
       subtitle: {
       text: 'Src: http://www.infochimps.com/datasets/world-crude-oil-production-1980-to-2004',
       x: -20
      },
       xAxis: {
         categories: _.map(this.column("Year").data, function(year) { 
         return year.format("YY"); 
       })
      },
       yAxis: {
         title: {
         text: this.columnNames()[1]
      },
       plotLines: [{
         value: 0,
         width: 10000,
         color: '#808080'
      }]
      },
       tooltip: {
         formatter: function() {
         return '<b>'+ this.series.name +'</b><br/>'+
         this.x +': '+ this.y;
      }
    },
       legend: {
        layout: 'vertical',
        align: 'right',
        verticalAlign: 'top',
        x: -10,
        y: 100,
        borderWidth: 0
    },
       series: [{
        name: 'World Production',
        data: this.column("Crude oil production (1000 barrels per day)").data
      }]
    });
  }
});
}
</script>
</html>

I know I've probably just failed to grasp something basic, as a beginner JS dev I'm learning a lot through making a lot of mistakes. Any help would be most appreciated!

Actually the output is calculated and kept in the js console. you are not telling to show it in the html level. To solve this, pass th output from js console to html output.

In chrome, go to dev tools(F12) and go to console. There you can see the desired output for the code you given in the question. So the output is showing, just take it out to the html front. For this you can use the method from this answer:Javascript: console.log to html

chrome dev tools's js console output looks like this

It seems I have fixed it. I needed to add $(document).ready( to my function encompassing all of the script. So:

$(document).ready(function() {

  var ds = new Miso.Dataset({
  url : "crudeoil.csv",
  delimiter : ",",
  columns : [{ name : "Year", type : "time", format : "YYYY" }]
    }); 

ds.fetch({
  success : function() {
    chart = new Highcharts.Chart({
      chart: {
        renderTo: 'test',
        type: 'column',
        marginRight: 130,
        marginBottom: 25
      },
      title: {
      text : 'World Crude Oil Barrel Production (1,000) per unit',
        x: -20 //center
      },
      subtitle: {
        text: 'Src: http://www.infochimps.com/datasets/world-crude-oil-production-1980-to-2004',
        x: -20
      },
      xAxis: {
        categories: _.map(this.column("Year").data, function(year) { 
          return year.format("YY"); 
        })
      },
      yAxis: {
        title: {
          text: this.columnNames()[1]
        },
        plotLines: [{
          value: 0,
          width: 10000,
          color: '#808080'
        }]
      },
      tooltip: {
        formatter: function() {
          return '<b>'+ this.series.name +'</b><br/>'+
          this.x +': '+ this.y;
        }
      },
      legend: {
          layout: 'vertical',
          align: 'right',
          verticalAlign: 'top',
          x: -10,
          y: 100,
          borderWidth: 0
      },
      series: [{
          name: 'World Production',
          data: this.column("Crude oil production (1000 barrels per day)").data
      }]
    });
  }
});
});

In case anyone encounters the same problem, I hope this helps!
