jpgraph不起作用 [英] jpgraph doesn't work

问题描述

我正在开发有关统计信息的Web应用程序，因此我在使用库 jpgraph

I am developing a web application about statistics, so I am using the library jpgraph

出问题的是该图形没有出现.仅显示浏览器的残破图像图标.

What is going wrong is that the graph does not appear. Displays only the browser's broken image icon.

$num  = 20;
$num2 = 10;
$data = array($num,$num2);

$graph = new PieGraph(300,200);
$graph->SetShadow();
$graph->title->Set("Utilizadores Registados");

$p1 = new PiePlot($data);
$graph->Add($p1);
$graph->Stroke();

我确定GD已启用.

谢谢！

推荐答案

我的猜测是您的输出包含PHP错误消息，例如:

My guess is that your output contains PHP error messages, such as:

Fatal error: Class 'PieGraph' not found

浏览器往往使检查生成图像的脚本的源代码变得很困难，但是您应该找到一种实现方法.注释掉这一行:

Browsers tend to make it difficult to inspect the source code of a script that generates an image but you should find a way to do it. Commenting out this line:

$graph->Stroke();

...可以作为起点.

... can be a starting point.
