What Chart Enhancements Do You Need?

Hi, I did what is supposed I should be doing but I am no able to make it works. 

This is the "paste" I used, 

(function(){

  var querystring=document.location.search;

    var urlChart = URLRoot() &"db/bniy76a59?a=q&qid=11";
   
   
    $(win.document).ready(function() {
     console.log("hi");
    setTimeout(function() {
        var injectedScript = "<script>";
        injectedScript += "var chart = Highcharts.Chart[0];";
        injectedScript += "var options = chart.options;";
        injectedScript += "chart.destroy();";
        injectedScript += "options.yAxis[0].min = 0;";
        injectedScript += "options.yAxis[0].max = 80;";
        injectedScript += "new Highcharts.Chart(options);";
        injectedScript += "</script>";
        win.$(win.document.body).append(injectedScript);
      }, 2000);
    });
})();

If any one was able to made it work I would be thankful to get the script he used 

Thanks.
