Feeding Real Time Data By Javascript Method Feeddata()

[Jack Hunter]

I can't feed real time data on chart bay using the javascript method feedData(). The example shown in docmentation doesn't work. The method feedData() isn't recognized. There is not any running example on docs. Do someone has used this feature? Please, tell me how to.

Hi,

 

The Real Time data feeding to the chart using FusionCharts JavaScript API is working fine from our end.

 

Please have a look to the attached sample.

 

In this example the HTML button Click will call the JavaScript function where, random data is generated and fed to the chart.

 

Hope this helps!

Hey... did you check whether the chart has completely rendered before calling feedData? feedData should ideally be called after the chart's "rendererd" event is fired.

Hi, Sashibhusan... I'm very tanks for your help.I had tested this sample application, but it didn't worked here. The chart rendered successfully, however the method doesn't work. I'm debugging with firebug tool and it shows a message error like "chartRef.feedData is not a function". It's being curious... It must be a detail I'm not finding out. I've tested on mozila and IE navigators. So, let's see what I can do. If you discover something, please tell me. Thanks a lot.

Hi, shamasis... Yeah, the chart rendered successfully, but the method doesn't work. And yeah, I'm calling the method after the chart has been rendered.However, I'm tanks for your help.

Hey... one more basic check: If you are using Flash renderer, did you try ensuring that you have correct Flash Global Security Settings? Try: http://goto.fusioncharts.com/flash-global-security-settings-guide

Hi,

 

Could you please check if the chart has rendered successfully or not, before updating the data by using JavaScript function "feedData();"?

 

Please change the code as per the reference code provided below:

function feedDataToChart(){
var chartRef = FusionCharts("myChartId");
var currDate = new Date();
var label= currDate.getHours() + ":" + currDate.getMinutes() + ":" + currDate.getSeconds();
var randomValue = Math.floor(Math.random()*500)/100 + 30;
var strData = "&label=" + label + "&value=" + randomValue;
function FC_Rendered("myChartId"){
   	chartRef.feedData(strData);                     	
   	}
else{
   	alert("The Chart has not rendered. Unable to feed data.");
   	}
return;
}

 

Hope this helps!

Yeah, I got it! I switched from flash to JavaScript rendering mode. Like in http://docs.fusioncharts.com/widgets/Contents/FirstChart/UsingPureJS.html#force

 

Voila.

 

Tanks my fiends... Tanks for your heps.
