to zc1966() : 我用的是 $graph->title->SetColor(#....)
呢。可就是不起作用。文件如下：<?php
include ("src/jpgraph.php");
include ("src/jpgraph_log.php");
include ("src/jpgraph_line.php");if(array_key_exists("ydata",$_POST)) $ydata=$_POST['ydata'];
elseif(array_key_exists("ydata",$_GET)) $ydata=$_GET['ydata'];
else $ydata = "";//折线数据1
if(array_key_exists("ydata2",$_POST)) $ydata2=$_POST['ydata2'];
elseif(array_key_exists("ydata2",$_GET)) $ydata2=$_GET['ydata2'];

if(array_key_exists("graphHeight",$_POST)) $graphHeight=$_POST['graphHeight'];
