 Using pChart on Moodle Hi, I'm trying to use pChart Library on a Module for Moodle (development in php). I have in Moodle the next source code to show a graphic: Code: $imagepathurl = $CFG->wwwroot.'/mod/khronos/'; $element = $mform->getElement($this->_nameform.'graphic'); $element->setValue('<div class="mdl-align"><img src="'.$imagepathurl.'linegraph.php" alt="'.get_string('infographic', 'khronos').'" /></div>'); I call to the script php linegraph.php, and the result is a graphic. But I want to customize the values of the axis, for example, "Serie 1", "Serie 2", etc. With an array that I generate before the call. The code of the graphic: Code: <?php
require_once(dirname(dirname(dirname(__FILE__))).'/config.php'); //Includes
global $CFG, $USER;
/* pChart library inclusions */
include($CFG->dirroot.'/mod/khronos/class/pData.class.php');
include($CFG->dirroot.'/mod/khronos/class/pDraw.class.php');
include($CFG->dirroot.'/mod/khronos/class/pImage.class.php');
$myData = new pData();
$myData->addPoints(array(6,0,0,4,2,1,0,0),"Serie1");
$myData->setSerieDescription("Serie1","Serie 1");
$myData->setSerieOnAxis("Serie1",0);
$myData->addPoints(array(0,2,2,1,0,1,1,4),"Serie2");
$myData->setSerieDescription("Serie2","Serie 2");
$myData->setSerieOnAxis("Serie2",0);
$myData->addPoints(array(0,0,0,5,0,4,1,0),"Serie3");
$myData->setSerieDescription("Serie3","Serie 3");
$myData->setSerieOnAxis("Serie3",0);
$myData->addPoints(array("January","","","April","","","July",""),"Absissa");
$myData->setAbscissa("Absissa");
$myData->setAxisPosition(0,AXIS_POSITION_LEFT);
$myData->setAxisName(0,"1st axis");
$myData->setAxisUnit(0,"");
$myPicture = new pImage(700,230,$myData,TRUE);
$myPicture->drawRectangle(0,0,699,229,array("R"=>0,"G"=>0,"B"=>0));
$myPicture->setShadow(TRUE,array("X"=>1,"Y"=>1,"R"=>50,"G"=>50,"B"=>50,"Alpha"=>20));
$myPicture->setShadow(FALSE);
$myPicture->setGraphArea(50,50,675,190);
$myPicture->setFontProperties(array("R"=>0,"G"=>0,"B"=>0,"FontName"=>"fonts/pf_arma_five.ttf","FontSize"=>6));
$Settings = array("Pos"=>SCALE_POS_LEFTRIGHT
, "Mode"=>SCALE_MODE_FLOATING
, "LabelingMethod"=>LABELING_ALL
, "GridR"=>255, "GridG"=>255, "GridB"=>255, "GridAlpha"=>50, "TickR"=>0, "TickG"=>0, "TickB"=>0, "TickAlpha"=>50, "LabelRotation"=>0, "CycleBackground"=>1, "DrawXLines"=>1, "DrawSubTicks"=>1, "SubTickR"=>255, "SubTickG"=>0, "SubTickB"=>0, "SubTickAlpha"=>50, "DrawYLines"=>ALL);
$myPicture->drawScale($Settings);
$myPicture->setShadow(TRUE,array("X"=>1,"Y"=>1,"R"=>50,"G"=>50,"B"=>50,"Alpha"=>10));
$Config = array("DisplayValues"=>1);
$myPicture->drawLineChart($Config);
$Config = array("FontR"=>0, "FontG"=>0, "FontB"=>0, "FontName"=>"fonts/pf_arma_five.ttf", "FontSize"=>6, "Margin"=>6, "Alpha"=>30, "BoxSize"=>5, "Style"=>LEGEND_NOBORDER
, "Mode"=>LEGEND_HORIZONTAL
);
$myPicture->drawLegend(563,16,$Config);
$myPicture->stroke();
?> I want to change the next: Code: $myData->addPoints(array(6,0,0,4,2,1,0,0),"Serie1");
$myData->setSerieDescription("Serie1","Serie 1");
$myData->setSerieOnAxis("Serie1",0); By: Code: $myData->addPoints($graphData,"Serie1");
$myData->setSerieDescription("Serie1","Serie 1");
$myData->setSerieOnAxis("Serie1",0); But do not know how I can send this array to the file, to customize the data. Can you give me some help? Thank you very much.
