pChart 图表中文显示问题

解决方案 »

  1.   

    注释掉 header("content-type:text/html; charset=utf-8");
      

  2.   

    1、header 是不要的，因为你是以图片方式输出
    2、你选用的字体是西文字体，没有汉字当然不能显示，你需要选一款中文字体
    3、如果你的程序不是utf-8的，那么所有要输出的汉字都必须转成utf-8的
      

  3.   

    你选用的字体是西文字体，没有汉字当然不能显示，你需要选一款中文字体，就是我这个选错啦？$myPicture->setFontProperties(array("FontName"=>"fonts/pf_arma_five.ttf","FontSize"=>6));我改改去。。
      

  4.   

    假定你的服务器是 windows 系统，且程序是 gbk 编码的function bm($ar) {
      if(! is_array($ar)) return iconv('gbk', 'utf-8', $ar);
      foreach($ar as &$v) $v = iconv('gbk', 'utf-8', $v);
      return $ar;
    } /* CAT:Bar Chart */
     /* pChart library inclusions */
     include("Plugin/pChart2.1.4/class/pData.class.php");
     include("Plugin/pChart2.1.4/class/pDraw.class.php");
     include("Plugin/pChart2.1.4/class/pImage.class.php"); /* Create and populate the pData object */
     $MyData = new pData();
     $MyData->addPoints(array(150,220,300,250,420,200,300,200,100), bm("测试"));
     $MyData->setAxisName(0, bm("套"));
     $MyData->addPoints(bm(array("1月","2月","3月","4月","5月","6月","7月","8月","9月")),"Months");
     $MyData->setSerieDescription("Months","Month");
     $MyData->setAbscissa("Months"); /* Create the pChart object */
     $myPicture = new pImage(700,230,$MyData); /* Turn of Antialiasing */
     $myPicture->Antialias = FALSE; /* Add a border to the picture */
     $myPicture->drawGradientArea(0,0,700,230,DIRECTION_VERTICAL,array("StartR"=>240,"StartG"=>240,"StartB"=>240,"EndR"=>180,"EndG"=>180,"EndB"=>180,"Alpha"=>100));
     $myPicture->drawGradientArea(0,0,700,230,DIRECTION_HORIZONTAL,array("StartR"=>240,"StartG"=>240,"StartB"=>240,"EndR"=>180,"EndG"=>180,"EndB"=>180,"Alpha"=>20));
     $myPicture->drawRectangle(0,0,699,229,array("R"=>0,"G"=>0,"B"=>0)); /* Set the default font */
     $myPicture->setFontProperties(array("FontName"=>"c:/windows/fonts/simhei.ttf","FontSize"=>6)); /* Define the chart area */
     $myPicture->setGraphArea(60,40,650,200); /* Draw the scale */
     $scaleSettings = array("GridR"=>200,"GridG"=>200,"GridB"=>200,"DrawSubTicks"=>TRUE,"CycleBackground"=>TRUE);
     $myPicture->drawScale($scaleSettings); /* Write the chart legend */
     $myPicture->drawLegend(580,12,array("Style"=>LEGEND_NOBORDER,"Mode"=>LEGEND_HORIZONTAL)); /* Turn on shadow computing */ 
     $myPicture->setShadow(TRUE,array("X"=>1,"Y"=>1,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>10)); /* Draw the chart */
     $myPicture->setShadow(TRUE,array("X"=>1,"Y"=>1,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>10));
     $settings = array("Surrounding"=>-30,"InnerSurrounding"=>30);
     $myPicture->drawBarChart($settings);
     ob_clean();  //关键代码，防止出现'图像因其本身有错无法显示'的问题。
    Header("Content-type: image/PNG"); 
     /* Render the picture (choose the best way) */
     $myPicture->autoOutput("examples/pictures/example.drawBarChart.simple.png");
      

  5.   

    输出图表 我还是推荐到JS 那去处理...图表效果 比php的丰富多了.
