甘特图

甘特图

甘特图是一种条形图,由 Karol Adamiecki 在 1896 年首次开发,并由 Henry Gantt 在 1910 年代独立开发,说明了项目进度和任何一个项目完成所需的时间量。甘特图说明了一个项目的终端要素和摘要要素的开始和结束日期之间的天数。

给用户的说明

甘特图将把每个计划任务记录为一个连续的条形,从左边延伸到右边。X 轴代表时间,Y 轴记录不同的任务和它们完成的顺序。

重要的是要记住,当一个任务的特定日期、日子或日期集合被 “排除” 时,甘特图将通过向右延伸相同数量的日子来适应这些变化,而不是在任务内部创建一个缺口。

但是,如果被排除的日期在两个被设定为连续开始的任务之间,被排除的日期将被图形化地跳过,留出空白,下面的任务将在被排除日期结束后开始。

甘特图对于跟踪一个项目完成前所需的时间非常有用,但它也可以用来用图形表示 “非工作日”,只需做一些调整。

Mermaid 可以将甘特图呈现为 SVG、PNG 或 MarkDown 链接,可以粘贴到文档中。

标题

title 是一个 可选的 字符串,显示在甘特图的顶部,用来描述整个图表。

章节声明

你可以将图表划分为不同的部分,例如将项目的不同部分如开发和文档分开。

为此,用 section 关键字开始一行,并给它一个名字。(注意,与 整个图表的标题 不同,这个名字是 必须的)。

里程碑

你可以在图表中添加里程碑。里程碑与任务不同,它们代表一个单一的时间点,并以关键字 milestone 来标识。下面是一个关于如何使用里程碑的例子。你可能会注意到,里程碑的确切位置是由里程碑的初始日期和任务的 “duration” 决定的,这种方式:initial date+duration/2。

设置日期

dateFormat 定义了你的甘特图元素的日期 input 的格式。这些日期如何在渲染的图表 output 中表示,由 axisFormat 定义。

date 输入格式

默认的输入日期格式是 YYYY-MM-DD。你可以定义你的自定义 dateFormat

dateFormat YYYY-MM-DD

支持以下格式化选项:
