甘特图
甘特图是一种条形图,最初由 Karol Adamiecki 于 1896 年开发,并由 Henry Gantt 在 1910 年代独立开发,它说明了项目进度和任何一个项目完成所需的时间。甘特图说明项目的终端元素和摘要元素的开始日期和结束日期之间的天数。 给用户的说明甘特图将每个计划任务记录为一个从左向右延伸的连续条形图。x 轴代表时间,y 轴记录不同的任务及其完成的顺序。 重要的是要记住,当特定于任务的日期、日期或日期集合被“排除”时,甘特图将通过向右延伸相等的天数来适应这些变化,而不是通过在内部创建间隙任务。 但是,如果排除的日期在设置为连续开始的两个任务之间,则排除的日期将以图形方式跳过并留空,并且以下任务将在排除的日期结束后开始。 甘特图可用于跟踪项目完成之前所需的时间,但它也可用于以图形方式表示“非工作日”,只需进行一些调整。 Code Chart 可以将甘特图呈现为 SVG、PNG 或可以粘贴到文档中的 MarkDown 链接。 gantt title A Gantt Diagram dateFormat YYYY-MM-DD section Section A task :a1, 2014-01-01, 30d Another task :after a1 , 20d section Another Task in sec :2014-01-12 , 12d another task : 24dA Gantt Diagram2014-01-052014-01-122014-01-192014-01-262014-02-022014-02-092014-02-16A task Task in sec another task Another task SectionAnotherA Gantt Diagram句法gantt dateFormat YYYY-MM-DD title Adding GANTT diagram functionality to Code Chart excludes weekends %% (`excludes` accepts specific dates in YYYY-MM-DD format, days of the week ("sunday") or "weekends", but not the word "weekdays".) section A section Completed task :done, des1, 2014-01-06,2014-01-08 Active task :active, des2, 2014-01-09, 3d Future task : des3, after des2, 5d Future task2 : des4, after des3, 5d section Critical tasks Completed task in the critical line :crit, done, 2014-01-06,24h Implement parser and jison :crit, done, after des1, 2d Create tests for parser :crit, active, 3d Future task in critical line :crit, 5d Create tests for renderer :2d Add to Code Chart :1d Functionality added :milestone, 2014-01-25, 0d section Documentation Describe gantt syntax :active, a1, after des1, 3d Add gantt diagram to demo page :after a1 , 20h Add another diagram to demo page :doc1, after a1 , 48h section Last section Describe gantt syntax :after doc1, 3d Add gantt diagram to demo page :20h Add another diagram to demo page :48h Adding GANTT diagram functionality to Code Chart2014-01-072014-01-092014-01-112014-01-132014-01-152014-01-172014-01-192014-01-212014-01-232014-01-252014-01-27Completed task Completed task in the critical line Implement parser and jison Describe gantt syntax Active task Create tests for parser Add gantt diagram to demo page Add another diagram to demo page Future task Future task in critical line Describe gantt syntax Add gantt diagram to demo page Add another diagram to demo page Future task2 Create tests for renderer Add to Code Chart Functionality added A sectionCritical tasksDocumentationLast section Adding GANTT diagram functionality to Code Chart可以设置多个以空格分隔的依赖项: gantt apple :a, 2017-07-20, 1w banana :crit, b, 2017-07-23, 1d cherry :active, c, after b a, 1d2017-07-202017-07-212017-07-222017-07-232017-07-242017-07-252017-07-262017-07-272017-07-28apple banana cherry 标题这title是一个可选的字符串,显示在甘特图的顶部,用于描述整个图表。 部分语句您可以将图表分成不同的部分,例如将项目的不同部分(如开发和文档)分开。 为此,请以section关键字开始一行并为其命名。(请注意,与整个图表的标题不同,此名称是必需的。 里程碑您可以将里程碑添加到图表中。里程碑与任务不同,因为它们代表一个单一的时间瞬间并由关键字标识milestone。以下是有关如何使用里程碑的示例。您可能会注意到,里程碑的确切位置是由里程碑的初始日期和任务的“持续时间”决定的:初始日期+持续时间/2。 gantt dateFormat HH:mm axisFormat %H:%M Initial milestone : milestone, m1, 17:49,2min taska2 : 10min taska3 : 5min Final milestone : milestone, m2, 18:14, 2min17:5017:5518:0018:0518:10Initial milestone taska2 taska3 Final milestone 设置日期dateFormat定义甘特图元素的日期输入格式。这些日期在呈现的图表输出中的表示方式由 定义axisFormat。 输入日期格式默认输入日期格式为YYYY-MM-DD. 您可以定义您的自定义dateFormat. dateFormat YYYY-MM-DD支持以下格式选项: Input Example Description: YYYY 2014 4 digit year YY 14 2 digit year Q 1..4 Quarter of year.
