So I need to plot about 120 bar charts on my screen, so I do the following

var barPlot = $.jqplot(targetDiv, jsonBarObj, createBarChartOption(jsonLegendObj, jsonColsObj))

targetDiv is the id of different div on the page like barDiv1, barDiv2 ...

In IE9, the browser hang very often. so my idea to store the JQPlot object to barPlot like above, then if not null, then barPlot.replot(). The problem I ran into is how do I specify the a new target Id. I try 

barPlot.targetId = "#" + targetDiv;

but this does not work. Please help

EDIT: here is jsfiddle: http://jsfiddle.net/YX9wX/5/

Click load, and if you alt+tab away and alt_tab back, you can see it hang on IE9, and hang until it finish all the drawing

Perhaps I misunderstood your question, but... you have some HTML div targets (20?):

<div id="targetDiv1"></div>
<div id="targetDiv2"></div>
<div id="targetDiv3"></div>

A common data (any):

var data = [[[1, 2], [3, 5.12], [5, 13.1], [7, 33.6], [9, 85.9], [11, 219.9]]];

One first plot in a div target with some concrete render options (say, blue color):

var barPlot = $.jqplot("targetDiv1", data, {series: [{color: "#0000ff"}]});

And then do you want to replot the same data in some different div targets with other render options?

If so, try to call the initmethod and then replot:

barPlot.init("targetDiv2", barPlot.data, {series: [{color: "#ff0000"}]});
barPlot.replot({clear: false});

barPlot.init("targetDiv3", barPlot.data, {series: [{color: "#ff00ff"}]});
barPlot.replot({clear: false});

  • ohh thanks. I will give it a try, and see if this will help me solve the memory problem in IE if I draw lots of graphs – Thang Pham Jan 02 '13 at 19:01

I think the best way to deal with IE hanging is to give the browser a short break after each plot:

$(function(){createPlot(1);});

function createPlot(plotIndex){
  var targetDiv = "barDiv" + plotIndex;
  // define jsonBarObj, jsonLegendObj & jsonColsObj here
  $.jqplot(targetDiv, jsonBarObj, createBarChartOption(jsonLegendObj, jsonColsObj))
  if(plotIndex < 20) setTimeout(function(){createPlot(++plotIndex);},1);
}

EDIT From Thang Pham

In combine with this, you can call destroy() on jqplot object to release it to fix the issue with leaking memory. However since call destroy() on jqplot object will make the chart disappear, I convert the jqplot chart to image using

https://bitbucket.org/cleonello/jqplot/issue/14/export-capabilities#comment-554274

the method from the above link will return base64 image string, which to can feed to <img> using jQuery. Once that is done, you can safely call destroy() on jqplot object.

  • yeah, it hang (not responding) until it finish all the drawing and then all the plot show. sorry I was so busy with other task at hand, that I could not do jsfiddle, doing it now – Thang Pham Jan 09 '13 at 14:56
  • Thank you, for some reason it works on the jsfiddle, but on the my system, it still attempt to draw all of them at once instead of drawing one by one like the example. so weird. Any more idea? – Thang Pham Jan 09 '13 at 19:28
  • Try changing the timeout period from 1 to 100 milliseconds: `setTimeout(function(){createPlot(++plotIndex);},100);`. If the charts still draw all at the same time then recheck your code. – ic3b3rg Jan 09 '13 at 19:57
  • Not sure what the problem is but I've added a full working html for you to test. – ic3b3rg Jan 09 '13 at 20:36
  • Can you please attach jsfiddle.net/YX9wX/6 to your answer, I will award boundty after that. Thank you – Thang Pham Jan 10 '13 at 00:24
  • Thanks! What do you mean by 'attach jsfiddle.net/YX9wX/6 to your answer'? – ic3b3rg Jan 10 '13 at 00:30
  • Ohh just want you have the link to the jsfiddle as part of your answer. It is easy for other to see the jsfiddle outcome. – Thang Pham Jan 10 '13 at 00:54

I would try a different approach.

Ok, IE hangs when you are creating 20 graphs, but other browsers hang also, but just shorter. If you are loading a lot of data in your graphs, all browsers will hang. It is also depending on the computer performance and specific plateforms like browsers on phones for example.

The best basic design pattern I know to load big content is to use a loading layer and load a page with big content using JQuery load() function. This function will hang your browser durring loading (synchrone mode), but a message with an image will be displayed for the user comprehension.

In your case, you could have a div graphs-container hidden by default in your web page, use a div to display a loading animation (or apply a loading layer by CSS class to your graphs-container visible by default in this case), then load your big page using JQuery load() function. In the success loading callback, you can hide the loading layer and reveal the loaded page, all the graphs in your case.

Usually, I compose the loading layer class with an animate gif wheel and a simple text.

To improve the rendering performance and save the user bandwidth, you can also compress web pages using PHP ob-gzhandler or directly using .htaccess rules : http://www.xpertdeveloper.com/2012/04/htaccess-gzip-compression/

Another tip would be to load JS libs only once, JQPlot have a lot of plugins you are certainly using which take time to load.

Here is a possible implementation of a loading layer div to display a text with an animation durring the graphs-loading: 

<!-- The loading layer with loading message and animated GIF -->
<div id='graphs-loading-layer' class='loading'>Loading in progress...</div>

<!-- The target div to load all your graphs -->    
<div id='graphs-container'></div>

<!-- Loading class example -->        
<style>
    .loading{   
        border:1px dotted black;
        font-size:25px;
        background-color:white;
        background-image:url(./loading.gif);
        background-repeat:no-repeat;
        background-position:center center;
        opacity:0.6;
        z-index:200;
        width:99%;
        min-height:442px;
        border-radius: 10px;
        position:relative;
        text-align:center;
        line-height:300px;
    }
</style>

<script>
   //allJQPlotGraphs.php is the file (or a call to a controller in MVC model) where the graphs are generated
   $('#graphs-container').hide().load('allJQPlotGraphs.php',{/*JSON map data*/},function(){
      //Here is the success callback, fade out the loading layer div
      $('#graphs-loading-layer').fadeOut(300,function(){     
          //Then, display the graphs container with all graphs loaded
          $('#graphs-container').fadeIn(300);
      });      
   });
</script>
