Classe CMbGraph

   Guide du développeur  »  Tutoriels et outils  »  Classe CMbGraph

Cette classe permet de créer des graphique. Elle comprend toutes les fonctions permettant de créer des graphiques en baton, linéaire, camembert...Elle permet aussi de faire une abstraction de la bilbiothèque de création du graphique.

Vous pourrez trouver le code source de cette classe ici : classes/mbGraph

Fonctions

Constructeur

Pour répondre aux différents paramètres des bibliothèques de création de graphique, un tableau d'option a été définit pour une utilisation plus aisé lors de la création. Des valeurs par défault ont été définis.

<?php
function CMbGraph() {
		global $dPconfig;
		$this->config = $dPconfig['graph_engine'];
		$this->options = array ("width" => 320,   //width of frame 
					"height" => 125,  //height of frame

Exemples

Accumulated bar plot

Le graphique "Accumulated bar plot" permet de réprésenter un graphique en bâton en accumulant plusieurs données.

<?php
$options = array( "width" => 480,
		  "height" => 300,
		  "title" => $title,
		  "subtitle" => $subtitle,
		  "sizeFontTitle" => 10,
		  "margin" => array(50,40,50,70),
		  "posLegend" => array(0.02, 0.06, "right", "top"), 
          "sizeFontAxis" => 8,
		  "labelAngle" => 50,
		  "textTickInterval" => 2,
		  "posXAbsDelta" => 15,
		  "posYAbsDelta" => -15,
		  "dataAccBar" => $patbyservice,
		  "datax" => $datax,
          "graphAccLegend" => $patbyservice,);			
$graph = new CMbGraph();
$graph->selectType("Graph",$options);
$graph->selectPalette($options);
$graph->setupAxis($options);
$graph->addAccBarPlot($options);
$graph->render("out",$options);
?>

Spline graph

Le graphique "Spline" est construit en reliant les points d'un repère interpolés

<?php
$options = array( "width" => 480,
		          "height" => 300,
			      "title" => $title,
			      "margin" => array(50,40,50,70),
			      "posLegend" => array(0.015,0.79, "right", "center"), 
			      "sizeFontAxis" => 8,
			      "labelAngle" => 50,
			      "textTickInterval" => 2,
			      "posXAbsDelta" => 15,
			      "posYAbsDelta" => -15,
			      "dataLine" => $op,
			      "datax" => $datax,
			      "scale" => array(0,intval($opSorted[0])+1),);		
$graph = new CMbGraph();
$graph->selectType("Graph",$options);
$graph->selectPalette($options);
$graph->setupAxis($options);
$graph->addSplinePlot($options);
$graph->render("out",$options);
?>
