项目需要，图表显示数据，个人能力有限，

 /* CAT:Bar Chart */ header("content-type:text/html; charset=utf-8"); /* pChart library inclusions */ include("class/pData.class.php"); include("class/pDraw.class.php"); include("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),"test"); $MyData->setAxisName(0,"Hits"); $MyData->addPoints(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"=>"fonts/pf_arma_five.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");

怎么把 $MyData->addPoints(array(150,220,300,250,420,200,300,200,100),"test");的字符串test显示为中文，怎么把 $MyData->setAxisName(0,"Hits");显示中文，比如 $MyData->setAxisName(0,"套");。。

回复讨论(解决方案)

直接中文写上去不行吗？

不行啊，直接什么都没有。

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

我开始没有的，然后后面加上去的，也没用啊，这不是乱码，只是不显示啊。。

是最新版的吗？
待会下一个看看

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

是最新版的吗？
待会下一个看看

是啊，是最新的，老版本也是这个问题，所以我索性用最新版本的了。谢谢老徐。。我在跟源码，慢慢研究。。求点拨

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。。

该用哪种字体呢？我用其他字体文件就是显示乱码，我定义了文体编码，没用，然后也用转码函数，也没用，怎么回事呢！？

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");
