php jpgraph library is very powerful and can generate images in the background

Backend generation is very useful when you need to export chart-type reports. Of course, front-end visualization still requires the use of highcharts/echarts/anycharts and other class libraries

What is more troublesome is the problem of garbled Chinese characters. There are garbled characters in three places:

legend
setStickLabels
title

First explain my environment and version:

Ubuntu12.04
PHP 5.3.10-1
Jpgraph 3.5.0b1
File fileencoding=utf-8

Legend garbled characters

  //jpgraph_legend.inc.php
  3 class Legend {
  2     public $txtcol=array();
  1     //public $font_family=FF_DEFAULT,$font_style=FS_NORMAL,$font_size=8; // old. 12
  0     public $font_family=FF_SIMSUN,$font_style=FS_NORMAL,$font_size=8; // old. 12

Remember to download a copy of simsun.ttc and put it in /usr/share/fonts/truetype

   //jpgraph_ttf.inc.php
  9         elseif( $aFF === FF_SIMSUN ) {
  8             // Do Chinese conversion 
  7             /*
  6             if( $this->g2312 == null ) {
  5                 include_once 'jpgraph_gb2312.php' ;
  4                 $this->g2312 = new GB2312toUTF8();
  3             }
  2             return $this->g2312->gb2utf8($aTxt);
  1              */
  0             return $aTxt;<br />
  1         }

I refer to the above solution:

Then the next two I think are the places to find the title/stickLabels source code, change FFDEFAULT to FFSIMSUN

It turns out that this is indeed the case, and conveniently these 2 guys are both in the jpgraph.php file

Directly

:%s/FF_DEFAULT/FF_SIMSUN/g

That’s it

title garbled

  2         $this->title = new Text();
  1         $this->title->ParagraphAlign('center');
  0         //$this->title->SetFont(FF_DEFAULT,FS_NORMAL); //FF_FONT2, FS_BOLD<br />
  1         $this->title->SetFont(FF_SIMSUN,FS_NORMAL); //FF_FONT2, FS_BOLD

stickLables garbled characters

  5 class AxisPrototype {
  4     public $scale=null;
  3     public $img=null;
  2     public $hide=false,$hide_labels=false;
  1     public $title=null;
  0     public $font_family=FF_DEFAULT,$font_style=FS_NORMAL,$font_size=8,$label_angle=0;

Copy after login

There is also a place with FF_DEFAULT,

  5 class DisplayValue {
  4     public $margin=5;
  3     public $show=false;
  2     public $valign='',$halign='center';
  1     public $format='%.1f',$negformat='';
  0     private $ff=FF_DEFAULT,$fs=FS_NORMAL,$fsize=8;
