在本文中主要是使用ChartDirector的 Python版本来创建出多层级的甘特图,而在此次的示例演示中将会包含两个图层,包含计划和实际情况的甘特图,XYChart.addBoxWhiskerLayer 创建的两个图层,使用BaseBoxLayer.setDataWidth来进行在栏的顶部的图层的宽度的设置,以便它不会挡住底部的图层。
具体示例的源代码如下,和大家一起分享分享:
#!/usr/bin/python from pychartdir import * # the names of the tasks labels = ["Market Research", "Define Specifications", "Overall Archiecture", "Project Planning", "Detail Design", "Software Development", "Test Plan", "Testing and QA", "User Documentation"] # the planned start dates and end dates for the tasks startDate = [chartTime(2004, 8, 16), chartTime(2004, 8, 30), chartTime(2004, 9, 13), chartTime(2004, 9, 20), chartTime(2004, 9, 27), chartTime(2004, 10, 4), chartTime(2004, 10, 25), chartTime(2004, 11, 1), chartTime(2004, 11, 8)] endDate = [chartTime(2004, 8, 30), chartTime(2004, 9, 13), chartTime(2004, 9, 27), chartTime(2004, 10, 4), chartTime(2004, 10, 11), chartTime(2004, 11, 8), chartTime(2004, 11, 8), chartTime(2004, 11, 22), chartTime(2004, 11, 22)] # the actual start dates and end dates for the tasks up to now actualStartDate = [chartTime(2004, 8, 16), chartTime(2004, 8, 27), chartTime(2004, 9, 9), chartTime(2004, 9, 18), chartTime(2004, 9, 22)] actualEndDate = [chartTime(2004, 8, 27), chartTime(2004, 9, 9), chartTime(2004, 9, 27 ), chartTime(2004, 10, 2), chartTime(2004, 10, 8)] # Create a XYChart object of size 620 x 280 pixels.
