支持中文配置

1、修改jpgraph_ttf.inc.php

搜索CHINESE_TTF_FONT选项，修改常量的值是支持中文的字体

define('CHINESE_TTF_FONT','SIMYOU.TTF');

2.支持图例中文

修改jpgraph_legend.inc.php

public $font_family=FF_CHINESE,$font_style=FS_NORMAL,$font_size=8; // old. 12

3.test.php

 $graph->title->SetFont(FF_CHINESE);

$test.php

<?php

require_once '../src/jpgraph.php';
require_once '../src/jpgraph_line.php';

$graph = new Graph(600, 400);
/**
 * lin直线
 * text文本
 * int整数
 * long对数
 * textint
 */
$aAxisType = 'textint';
$graph->SetScale($aAxisType);
//设置统计图的标题
$graph->title->SetFont(FF_CHINESE);
$graph->title->Set('慕课网');

$data = array(0 => 10, 1 => 20, 2 => 30, 3 => 40, 4 => 50, 5 => 12, 6 => 38, 7 => 55, 8 => 100,
    9 => 120, 10 => 30, 11 => 54
);
$linePlot = new LinePlot($data);
//设置图例
$linePlot->SetLegend('测试中文');
//将统计图添加到画布上
$graph->Add($linePlot);
//设置统计图的颜色 一定要在添加到画布之后再设置
$linePlot->SetColor('red');

$graph->Stroke();
