Hi all,
i was wondering if someone is able to tell me how to integrate pChart in codeigniter.
I have read so many posts about this, but with no results.
Here is what i was doing by my self just for testing if all was going right:
I have created 3 libraries called pimage, pdraw and pdata, and i have pasted the code as it is, modifying only the declaration of the class as this :
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/* Axis configuration */
define("AXIS_FORMAT_DEFAULT" , 680001);
define("AXIS_FORMAT_TIME" , 680002);
define("AXIS_FORMAT_DATE" , 680003);
define("AXIS_FORMAT_METRIC" , 680004);
define("AXIS_FORMAT_CURRENCY" , 680005);
define("AXIS_FORMAT_TRAFFIC" , 680006);
define("AXIS_FORMAT_CUSTOM" , 680007);
/* Axis position */
define("AXIS_POSITION_LEFT" , 681001);
define("AXIS_POSITION_RIGHT" , 681002);
define("AXIS_POSITION_TOP" , 681001);
define("AXIS_POSITION_BOTTOM" , 681002);
/* Families of data points */
define("SERIE_SHAPE_FILLEDCIRCLE" , 681011);
define("SERIE_SHAPE_FILLEDTRIANGLE" , 681012);
define("SERIE_SHAPE_FILLEDSQUARE" , 681013);
define("SERIE_SHAPE_FILLEDDIAMOND" , 681017);
define("SERIE_SHAPE_CIRCLE" , 681014);
define("SERIE_SHAPE_TRIANGLE" , 681015);
define("SERIE_SHAPE_SQUARE" , 681016);
define("SERIE_SHAPE_DIAMOND" , 681018);
/* Axis position */
define("AXIS_X" , 682001);
define("AXIS_Y" , 682002);
/* Define value limits */
define("ABSOLUTE_MIN" , -10000000000000);
define("ABSOLUTE_MAX" , 10000000000000);
/* Replacement to the PHP NULL keyword */
define("VOID" , 0.123456789);
/* Euro symbol for GD fonts */
define("EURO_SYMBOL" , utf8_encode("€"));
class CI_Pdata {
/*

var $Data;
var $Palette = array("0"=>array("R"=>188,"G"=>224,"B"=>46,"Alpha"=>100),
"1"=>array("R"=>224,"G"=>100,"B"=>46,"Alpha"=>100),
"2"=>array("R"=>224,"G"=>214,"B"=>46,"Alpha"=>100),
"3"=>array("R"=>46,"G"=>151,"B"=>224,"Alpha"=>100),
"4"=>array("R"=>176,"G"=>46,"B"=>224,"Alpha"=>100),
"5"=>array("R"=>224,"G"=>46,"B"=>117,"Alpha"=>100),
"6"=>array("R"=>92,"G"=>224,"B"=>46,"Alpha"=>100),
"7"=>array("R"=>224,"G"=>176,"B"=>46,"Alpha"=>100));
/* Class creator */
function pData()
{
$this->Data = "";
$this->Data["XAxisDisplay"] = AXIS_FORMAT_DEFAULT;
$this->Data["XAxisFormat"] = NULL;
$this->Data["XAxisName"] = NULL;
$this->Data["XAxisUnit"] = NULL;
$this->Data["Abscissa"] = NULL;
$this->Data["AbsicssaPosition"] = AXIS_POSITION_BOTTOM;
$this->Data["Axis"][0]["Display"] = AXIS_FORMAT_DEFAULT;
$this->Data["Axis"][0]["Position"] = AXIS_POSITION_LEFT;
$this->Data["Axis"][0]["Identity"] = AXIS_Y;
}
..................................
the rest of the code is equal to the rest of the normal pdata class findable in pData class of pChart.
now, back to codeigniter, into y controller i wrote :
Code:
$this->load->library('pdata');
$this->load->library('pdraw');
$this->load->library('pimage');
$myData =& $this->pdata;
$myData->addPoints(array(VOID,3,4,3,5));
$myPicture =& $this->pimage;
$myPicture -> pImage(700,230,$myData);
$myPicture->setFontProperties(array("FontName"=>"fonts/Forgotte.ttf","FontSize"=>11));
$myPicture->setGraphArea(60,40,670,190);
$myPicture->drawScale();
$myPicture->drawSplineChart();
$myPicture->Stroke();
But it still gives me errors, sooooo many errors.
Now, the question is : Can anyone help me about the integration of this pChart into codeIgniter with a mini HOW TO?
Thanks,
Cristian
