<?php <br /><br>$datay=array();      //纵坐标数据<br><br>$datax=array();     //横坐标数据<br><br>foreach ($usernums as $key => $value){<br>$datay[] = $value;<br>$datax[] = $userids[$key];<br>}<br><br>require_once (‘jpgraph-3.0.7/jpgraph/jpgraph.php’);<br>require_once (‘jpgraph-3.0.7/jpgraph/jpgraph_bar.php’);<br><br>// Create the graph. These two calls are always required<br>$graph = new Graph(800,600);    //图像高宽<br>$graph->SetScale(“textlin”);<br><br>$graph->xaxis->SetTickLabels($datax);<br><br>$graph->xaxis->SetFont(FF_VERDANA,FS_NORMAL,10);<br>$graph->xaxis->SetLabelAngle(30);<br><br>$graph->yaxis->scale->SetGrace(20);<br>$graph->xaxis->scale->SetGrace(20);<br>// Add a drop shadow<br>$graph->SetShadow();<br><br>// Adjust the margin a bit to make more room for titles<br>$graph->img->SetMargin(40,30,20,40);<br><br>// Create a bar pot<br>$bplot = new BarPlot($datay);<br><br>// Adjust fill color<br>$bplot->SetFillColor(‘orange’);<br>$bplot->value->Show();<br>$bplot->value->SetFont(FF_ARIAL,FS_BOLD,10);<br>$bplot->value->SetAngle(45);<br>$bplot->value->SetFormat(‘%d’);<br>$graph->Add($bplot);<br><br>// Setup the titles<br>$graph->title->Set(iconv(“UTF-8″, “gb2312″,”用户消费报表图”));<br>$graph->xaxis->title->Set(iconv(“UTF-8″, “gb2312″,”用户姓名”));<br>$graph->yaxis->title->Set(iconv(“UTF-8″, “gb2312″,”用户订单数量”));<br><br>$graph->xaxis->title->SetFont(FF_SIMSUN,FS_BOLD);<br>$graph->yaxis->title->SetFont(FF_SIMSUN,FS_BOLD);<br>$graph->title->SetFont(FF_SIMSUN,FS_BOLD);<br><br>// Display the graph<br>$graph->Stroke();<br><br>?>
