jpgraph php 그림 예 일하다 강한 보고서 예 제3자

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

$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();
