New Post: Unable to populate series name while plotting line graph.

madhukanth2005 — Tue, 12 Mar 2013 08:51:48 GMT

Hi,
I have a json object in the below format.
[{"articleName":"Spring","articleQuantity":[32,20,53,42,28,18,41,72,66,90,48,28]},{"articleName":"Struts","articleQuantity":[55,27,60,36,46,90,15,22,51,48,72,80]},{"articleName":"Hibernate","articleQuantity":[33,24,64,72,15,50,80,92,20,18,6,88]}]
I have written the below logic and its working absolutely fine.

series:[

                    {
                        name:'Spring',
                        data: []
                    },
                    {
                        name:'Struts',
                        data: []
                    },
                    {
                        name:'Hibernate',
                        data: []
                    }        
            ]



},
function requestData() {
  $.ajax({
      type: "GET",
      url: "graph.html",
          success: function(response){
              var chartData=[];

        for(var i=0;i<=pointSpr.length;i++){
            chartData=[];   
             $.each(pointSpr[i].articleQuantity, function(k, v){
                        chartData.push(v);
                    });

          chart.series[i].setData(chartData);

        }
          },
         error: function(e){
                  alert('Error: ' + e);

              }


  })
}
);

});

});

But my problem is, if you look at the series name i,e Spring ,Struts and Hibernate, its all hard coded and i am want this thing to be dynamically taken instead of hard coding. I am using Spring MVC and HighCharts.Kindly help me out. Thanks in advance.

New Post: PostBack Issue not displaying a pie chart.

ricky1205 — Thu, 24 Jan 2013 21:25:29 GMT

Hello there:

First of all i like to congratulate to developrs who made this great solution. Thanks a lot.

Second i followed the example to display a pie chart successfully, it loads correctly and thats ok. After that i've deployed the same code to display ina web page that is child of a master page.

when it loads the first time(is not postback), it diplays correctly, a pie chart with its series, and whole colors. but when i raise a postback event (in this example a dropdown_selectedindexchanged event) i load new data to the chart and then the chart only displays its series, without a pie inside it. (i mean the circle with all its slices).

i've tried with an update panel, not worked. then with a Place holder adding a new PieChart control to it, also not worked.

if anybody have a functional solutions i'll appreciate it.

P.D. sorry for my english, i'm a bit rusty.

New Post: Problem adding Series to diferentes yAxis, the last serie display the Values of the first serie

pcarreiro — Sat, 20 Oct 2012 16:47:02 GMT

Hi,

I'am trying to add diferent series to diferent YAxis.

On the second Serie i have configured Serie.yAxis=1.

The chart appears the two Series, but with the same Data, Serie.yAxis = 1 has the values of the first serie.

If I add a third series with yAxis=1, the second appears the correct values, but the third appears the values of the first.

Who can i fix this?
