PHP JpGraph 中国語文字化け解決策

JpGraph はデフォルトでは中国語をサポートしていないため、セットアップする必要があります

しかし実際には変更する必要があるのは 2 か所だけです。場所は 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();?>

です。
