highcharts result is not stable

[zhang]

Hi, i found one small bug. when i refresh the chart page with firefox or chrome. the chart results are not same. For example. if i have 3 series, when i refresh it, sometime there is only 2 serises, sometime there are 3 series. BTW, i am using the Version 2.0.0 (2010-07-13) of highchart. There is no problem when i use the older one.

You can refresh it with chrome about 3 or 4 time. with firefox, it needs more time refresh to see the result

@zhang, you have 3 asynchronous AJAX requests there. The last one calls chart initialization. But it doesn't mean that the last requests returns last, too. The problem is that sometimes third request returns from server before the others and immediately calls Highchart.Chart() with options that don't contain all other series yet.
The solution is simple. Initialize chart first, and then call JSON requests who will add series to exiting chart:

Code: Select all

...
chart = new Highcharts.Chart(options);
   
jQuery.getJSON('test1.json', null, function(data) {
  chart.addSeries({
    name:'2010',
    data: data
  });
});
     
jQuery.getJSON('test2.json', null, function(data) {
  chart.addSeries({
    name: '2009',
    data: data
  });
});
 
jQuery.getJSON('test3.json', null, function(data) {
  chart.addSeries({
    name: '2008',
    data: data
  });
});

/* new Highcharts.Chart(options); */

Well, you method indeed solved the problem. but there is another problem if we do like that.: the download function does not work. you can check it from http://users.metropolia.fi/~yongzhez/debug/test/building_monthly_heat_consumption.php the pdf or jpg.. which we downloaded is empty.

The export utility doesn't include series added with addSeries, only those added in the initial config object. See http://github.com/highslide-software/hi ... s/issue/48.

Any other way to solve the first problem? It happens very often when we change the language. For example one chart can be displayed in two languages, when we press the language button, it will happen.

I have solved this problem
