PHP JpGraph中文乱码解决方式

JpGraph默认不支持中文，需要我们进行设置

但是实际测试中，我们只需要修改2个地方即可,位置是jpgraph_ttf.inc.php

<?php // content="text/plain; charset=utf-8"
require_once (‘../jpgraph.php‘);
require_once (‘../jpgraph_line.php‘);

 // Some (random) data
$ydata   = array(11, 3, 8, 12, 5, 1, 9, 13, 5, 7);
$ydata2  = array(1, 19, 15, 7, 22, 14, 5, 9, 21, 13 );

// Size of the overall graph
$width=350;
$height=250;

// Create the graph and set a scale.
// These two calls are always required
$graph = new Graph($width,$height);
$graph->SetScale(‘intlin‘);
$graph->SetShadow();

// Setup margin and titles
$graph->SetMargin(40,20,20,40);

$graph->title->Set(‘标题---统计图‘);
$graph->subtitle->Set(‘(March 12, 2008)‘);
$graph->xaxis->title->Set(‘X（跨度）‘);
$graph->yaxis->title->Set(‘Y（指数）‘);

// Create the first data series
$lineplot=new LinePlot($ydata);
$lineplot->SetWeight( 2 );   // Two pixel wide

// Add the plot to the graph
$graph->Add($lineplot);

// Create the second data series
$lineplot2=new LinePlot($ydata2);
$lineplot2->SetWeight( 2 );   // Two pixel wide

// Add the second plot to the graph
$graph->Add($lineplot2);

// Display the graph
$graph->Stroke();
?>
