Php pChart输出图像时出现问题。怎么了？

我在php页面中显示3DPie示例pChart时遇到问题，无论输出笔划、自动输出、渲染是什么，它都不会渲染到浏览器，但示例在示例文件夹中工作

我的问题是：为什么它不会呈现给浏览器？我怎么修理它？这不是包含，他们为基本语法教程工作

我花了很长时间才找到答案，最后我自己解决了这个问题，但是谢谢！哇！人们通常会逃避难答的问题。。糟糕的是我没能早点帮你+1即使在问题解决后接受，也应帮助将来有相同问题的其他人。我不仅做到了这一点，还有一个条形图从逗号分隔的文本文件中提取数据并显示出来。我花了很长时间才找到答案，最后我自己解决了这个问题，但谢谢！哇！人们通常会逃避难答的问题。。糟糕的是我没能早点帮你+1即使在问题解决后接受，也应帮助将来有相同问题的其他人。我不仅做到了这一点，还有一个条形图从逗号分隔的文本文件中提取数据并显示出来。
