用PEAR繪製各種統計圖

請先到官網下載Image_Graph套件，另外其他的套件也要下載喔
以下是我繪製圓餅圖的範例// create the graph $Graph =& Image_Graph::factory('graph', array(400, 300)); // add a TrueType font $Font =& $Graph->addNew('font', 'Arial'); // set the font size to 11 pixels $Font->setSize(8); $Graph->setFont($Font); // create the plotareas $Plotarea =& $Graph->addNew('plotarea'); $Plotarea->hideAxis(); // create the dataset //$Dataset =& Image_Graph::factory('random', array(10, 10, 20, true)); $Dataset =& Image_Graph::factory('dataset'); // create the 1st plot as smoothed area chart using the 1st dataset $Dataset->addPoint('Alex', 10); $Dataset->addPoint('Jim', 5); $Dataset->addPoint('Kevin', 6); $Plot =& $Plotarea->addNew('Image_Graph_Plot_Pie', $Dataset); /*加上百分比 start*/ // create a Y data value marker $Marker =& $Plot->addNew('Image_Graph_Marker_Value', IMAGE_GRAPH_PCT_Y_TOTAL); // create a pin-point marker type $PointingMarker =& $Plot->addNew('Image_Graph_Marker_Pointing_Angular', array(20, &$Marker)); // and use the marker on the 1st plot $Plot->setMarker($PointingMarker); // format value marker labels as percentage values $Marker->setDataPreprocessor(Image_Graph::factory('Image_Graph_DataPreprocessor_Formatted', '%0.1f%%')); /*加上百分比 end*/ $Plot->Radius = 2; // set a line color $Plot->setLineColor('gray'); // set a standard fill style $FillArray =& Image_Graph::factory('Image_Graph_Fill_Array'); $Plot->setFillStyle($FillArray); $FillArray->addColor('green@0.2'); $FillArray->addColor('blue@0.2'); $FillArray->addColor('yellow@0.2'); $FillArray->addColor('red@0.2'); $FillArray->addColor('orange@0.2'); // add a title using the created font $Graph->addNew('title', array('TEST PIE', 11)); //$Plot->explode(3); // output the Graph $Graph->done();
