[EXTENSION] Fusion Charts API Extension - Create and share Charts

bitmatix · June 14, 2010, 10:45am

How can I change the chartdata with an ajax action, i.e. when I change a dropdown?

josafafilho · July 8, 2010, 5:36pm

I had same problem, but i’m using utf8_decode() and works fine.


utf8_decode('ąčęėįšųūž')

Try it!

My two cent’s worth: it’s super important to clear the ‘assets’ folder - this isn’t covered in the FusionCharts Upgrade Instructions (well, for obvious reasons)

Hello:

I’m new to both yii as well as this extension, so forgive me if I’m making a rookie mistake somewhere along here.

I’m just trying to get any chart working, and I’m having trouble doing so.

I’ve stolen a lot of the code that has been mentioned in this thread, and as such my controller’s ‘actionChart’ looks like this:





    public function actionChart()

    {

        Yii::app()->fusioncharts->setChartOptions( array( 'caption'=>'test', 'xAxisName'=>'testx', 'yAxisName'=>'testy'));




        Yii::app()->fusioncharts->addCategory(array('label'=>'Cat1'));

        Yii::app()->fusioncharts->addCategory(array('label'=>'Cat2'));


        $options = array('seriesName' => 'Series1'); // must specify series anme

        Yii::app()->fusioncharts->addDataSet('data_unique_key', $options);

        $options = array('seriesName' => 'Series2'); // must specify series anme

        Yii::app()->fusioncharts->addDataSet('data_unique_key2', $options);




        $options = array('value' => 1);

        Yii::app()->fusioncharts->addSetToDataSet('data_unique_key', $options);

        $options = array('value' => 2);

        Yii::app()->fusioncharts->addSetToDataSet('data_unique_key', $options);


        $options = array('value' => 3);

        Yii::app()->fusioncharts->addSetToDataSet('data_unique_key2', $options);

        $options = array('value' => 4);

        Yii::app()->fusioncharts->addSetToDataSet('data_unique_key2', $options);




        Yii::app()->fusioncharts->useI18N = true;


        Yii::app()->fusioncharts->getXMLData(true);

    }

And my view’s widget instantiation looks like this:





$this->widget('ext.fusioncharts.fusionChartsWidget', array(   'debugMode' => true,

                                                              'chartNoCache'=>true, // disabling chart cache

                                                              'chartAction'=>Yii::app()->urlManager->createUrl('report/testchart'), // the chart action that we just generated the x

                                                              'chartId'=>'course_load')); // If you display more then one chart on a single page then make sure you specify and id

The result of which looks like this:

Different sub-domain of chart .swf and dataURL. Both need to be same owing to sandbox security.

And if I click on the dataURL invoked, I get: Unable to resolve the request "report/testchart".

Can anyone point out to me what I’m doing wrong? Do I have to build some sort of controller for report or some such?

Cheers,

eddieparker · January 20, 2011, 4:53am

Hrmm, OK, figured that much out - my basic Yii newbness biting me. My controller is called ‘Dashboard’, so the URL I need to supply is dashboard/chart. That fixed the problem, combined with changing it to an MSLine chartType.

Awesome.

Just a bit of feedback: it would be nice if there was a complete source pasting of a controller and view pair that worked in the documentation. It would be great if I could copy and paste some sample graph in my application and then start noodling with the parameters to see how the thing worked, versus having to cobble bits and pieces from this forum posting. But now that it works, I’m happy.

Cheers

Also, noticed a little bug:

In convertOptionsToXML() in fusioncharts.php:





651     /**

652      * Convert chart array options into encoded xml string

653      * @return string

654      */

655     protected function convertOptionsToXML( $options=array() )

656     {

657         $parsedXML = '';

658         if( count($options) )

659         {

660             $parsedXML = ' ';

661             foreach($options as $k => $v)

662             {

663                 if($v)

664                 {

665                     $parsedXML .= $k . "='" . $this->_encodeSpecialChars($v) . "' ";

666                 }

667             }

668         }

669

670         return $parsedXML;

671     }

The if($v) is what’s stopping me from using parameters like showValues=‘0’, and what not. I’m not sure what other problems disabling the if($v) could cause, but I’m doing it locally and haven’t noticed any problems.

Bonfreud · May 17, 2011, 6:00pm

Did someone manage to do that ? I just would like to do something like that: http://www.fusioncharts.com/fusioncharts23/Site_Doc/HelpDocs/Client_JS.html

Thanks

if you see that message you probably dont have flash.

maxotto · April 6, 2012, 12:40pm

Hi!

My company has got corporate version of Fusion Charts and I started to use it with Yii.

Unfortunately, I had got some errors using it with your extension. Some research on Fusion Charts Forum gave an answer: the name of JS variable and the name of DIV must be unequal.

So I changed chartjs.php

New version is in attachments 2753

chartjs.php

Now it works fine for me. Thank you for the great extension.

lakshmia · April 13, 2012, 9:03am

Hi,

am new to yii and this Fusion Charts.

I am also getting the same messge "The chart will appear within this DIV. This text will be replaced by the chart. My code below".

I changed chartjs.php as per the previous comment… and flash player is also installed in my system…

Can anyone please help me?

Im new at Yii and Im trying to use this extension:

Following the example of the extension

my code is like this:

Controller:


public function actionChart() {

		

		

		Yii::app ()->fusioncharts->setChartOptions ( array ('caption' => 'My Chart', 'xAxisName' => 'Months', 'yAxisName' => 'Revenue' ) );

		Yii::app ()->fusioncharts->addSet ( array ('label' => 'July', 'value' => '680000' ) );

		Yii::app ()->fusioncharts->addSet ( array ('label' => 'August', 'value' => '680000' ) );

		Yii::app ()->fusioncharts->addSet ( array ('label' => 'Jan', 'value' => '680000' ) );

	

		

		Yii::app ()->fusioncharts->addCategory ( array ('label' => 'Jan' ) );

		Yii::app ()->fusioncharts->addCategory ( array ('label' => 'Feb' ) );

		Yii::app ()->fusioncharts->addCategory ( array ('label' => 'Mar' ) );

	

		

		// Add two data sets

		Yii::app ()->fusioncharts->addDataSet ( 'data_unique_key', $options );

		Yii::app ()->fusioncharts->addDataSet ( 'data_unique_key2', $options );

	

		Yii::app ()->fusioncharts->addTrendLine ( array ('startValue' => '700000', 'color' => '009933', 'displayvalue' => 'Target' ) );

		Yii::app ()->fusioncharts->addDefinition ( array ('name' => 'CanvasAnim', 'type' => 'animation', 'param' => '_xScale', 'start' => '0', 'duration' => '1' ) );

		Yii::app ()->fusioncharts->addApplication ( array ('toObject' => 'Canvas', 'styles' => 'CanvasAnim' ) );

	

		Yii::app ()->fusioncharts->useI18N = true;

		

	}

And the view:


<?php 

// echo '<pre>';

// print_r(Yii::app ()->urlManager->createUrl ( 'file/chart' ));

// exit;


$this->widget ( 'ext.fusioncharts.fusionChartsWidget', array ('chartNoCache' => true, // disabling chart cache

		'chartAction' => Yii::app ()->urlManager->createUrl ( 'file/chart' ), // the chart

		// action that

		// we just

		// generated the

		// xml data at

		'chartId' => 'mychart' ) ); // If you display more then one chart on a single page

// then make sure you specify and id


?>

When I render the view I only can see "Error in loading data"

Can anybody help me??

Thanx a lot

hai everyone, i got stuck in this chart,

but i’d solve it

here is my controller

            Yii::app()->fusioncharts->addSet(array('label' => 'August', 'value' => '680000'));

            Yii::app()->fusioncharts->addSet(array('label' => 'Jan', 'value' => '680000'));

            

            Yii::app()->fusioncharts->addCategory(array('label' => 'Jan'));

            Yii::app()->fusioncharts->addCategory(array('label' => 'Feb'));

            Yii::app()->fusioncharts->addCategory(array('label' => 'Mar'));

            Yii::app()->fusioncharts->useI18N = true;

            

            $chart=Yii::app()->fusioncharts->getXMLData(true);

            //header('Content-type: text/xml');

            echo pack("C3", 0xef, 0xbb, 0xbf);

            

            $this->render('chart',array('model'=> $chart));

        }

in my index.php




<?

    echo $this->renderPartial('chart');

?>

and in my chart.php




<?php


$this->widget('ext.fusioncharts.fusionChartsWidget', array(   

    'debugMode' => false,

    'chartNoCache'=>true, // disabling chart cache

    'chartAction'=>Yii::app()->urlManager->createUrl('site/chart'), // the chart action that we just generated the x

    'chartId'=>'course_load')); // If you display more then one chart on a single page then make sure you specify and id

dieter:

I created a fresh YII application and now I am getting different results. However, it still is not working:

With Yii::app()->fusioncharts->getXMLData(true); the following data are displayed:

<chart caption="My Chart" xAxisName="Months" yAxisName="Revenue"><set label="Jan" value="6700"/><set label="July" value="7800"/><set label="August" value="8900"/></chart>

With Yii::app()->fusioncharts->getXMLData(false); the following error comes up:

No Data to Display: No data was found in the XML data document provided. Possible cases can be:

There isn’t any data generated by your system. If your system generates data based on parameters passed to it using dataURL, please make sure dataURL is URL Encoded.

You might be using a Single Series Chart .swf file instead of Multi-series .swf file and providing multi-series data or vice-versa.

Any thoughts?

By using ECHO I was able to make it work:

echo Yii::app()->fusioncharts->getXMLData(false);

</categories>

</chart>
