新手初识jpgraph肯定会遇到各种各样的问题,比如乱码什么的,本案例是jpgraph3.0.7制作,也经过本人的多次实验，解决乱码问题
复制代码 代码如下:
<?php $datay=array(); //纵坐标数据 $datax=array(); //横坐标数据 foreach ($usernums as $key => $value){ $datay[] = $value; $datax[] = $userids[$key]; } require_once (‘jpgraph-3.0.7/jpgraph/jpgraph.php’); require_once (‘jpgraph-3.0.7/jpgraph/jpgraph_bar.php’); // Create the graph. These two calls are always required $graph = new Graph(800,600); //图像高宽 $graph->SetScale(“textlin”); $graph->xaxis->SetTickLabels($datax); $graph->xaxis->SetFont(FF_VERDANA,FS_NORMAL,10); $graph->xaxis->SetLabelAngle(30); $graph->yaxis->scale->SetGrace(20); $graph->xaxis->scale->SetGrace(20); // Add a drop shadow $graph->SetShadow(); // Adjust the margin a bit to make more room for titles $graph->img->SetMargin(40,30,20,40); // Create a bar pot $bplot = new BarPlot($datay); // Adjust fill color $bplot->SetFillColor(‘orange’); $bplot->value->Show(); $bplot->value->SetFont(FF_ARIAL,FS_BOLD,10); $bplot->value->SetAngle(45); $bplot->value->SetFormat(‘%d’); $graph->Add($bplot); // Setup the titles $graph->title->Set(iconv(“UTF-8″, “gb2312″,”用户消费报表图”)); $graph->xaxis->title->Set(iconv(“UTF-8″, “gb2312″,”用户姓名”)); $graph->yaxis->title->Set(iconv(“UTF-8″, “gb2312″,”用户订单数量”)); $graph->xaxis->title->SetFont(FF_SIMSUN,FS_BOLD); $graph->yaxis->title->SetFont(FF_SIMSUN,FS_BOLD); $graph->title->SetFont(FF_SIMSUN,FS_BOLD); // Display the graph $graph->Stroke(); ?>
