ChartDirector for Python 制作甘特图
项目中经常要汇报进度，少不了甘特图，没有感觉特别趁手的工具。网上搜一搜，大部分是讲 Excel 制作甘特图的。今天在网上搜索，发现 ChartDirector 图表库可以制作甘特图，支持多种编程语言也包括 Python。百度对 CharDirector 是这样介绍的：
ChartDirector 是一款商业的图表库，有多种语言的版本，使用它做的图表非常的精细漂亮，提供免费版本，但会出现logo信息。
试用了一下，觉得可以满足部分甘特图制作，没有深度探索，暂做些记录。
ChartDirector for Python 安装
我是在 Windows 10 操作系统下安装，ChartDirector 版本是 6.0。安装与普通的 Python 模块不同，但也还简单。首先去官网下载，根据操作系统和编程语言选择合适的版本。
ChartDirector 的安装文件为 zip 压缩格式，解压后，我们可以看到 ChartDirector 文件夹下有这样几个文件夹：
将 lib 文件夹下所有文件（不是文件夹）拷贝到 python 安装目录的 site-packages 文件夹下面，下面的文件是拷贝的文件：
可以使用下面的方法查看 site-packages 文件夹位置：
>>> import sys
>>> for line in sys.path:
... print (line)
...
拷贝完成后用下面的导入命令检查安装，没有错误即表示安装成功：
from pychartdir import *
普通甘特图
下面的示例来自官方示例代码，代码在解压后的 pythondemos 文件夹下 gantt.py：
from pychartdir import *
