jpgraph是php中一个非常非常强大的第三方报表工具,据说能完成一切你想要的图形…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.

php报表 jpgraph柱状图实例代码如下:

<?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);//开源代码phpfensi.com

$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();
