pgfgantt 突出显示周末并在里程碑上画垂直线

Question

分割甘特图必须手动完成，正如 Torbjørn T. 已经提到的那样。里程碑的线条也不会内置到中pgfgantt。周末可以用

vgrid={*4{dotted},{red,dotted},dotted,{red,dotted}}

这适用于从周一开始的甘特图。对于其他工作日，必须使用不同的模式。

但pgfgantt可以扩展来做你想做的事情。

下面的代码提供了以下新选项：

虚拟网格周刊需要两个参数，用于垂直线。第二个参数用于周五和周六以及周日和周一之间的线。第一个参数用于所有其他线。它将覆盖使用完成的设置vgrid，即使后者位于此选项之后。无默认值。
周末背景设置周六和周日的背景颜色。如果设置为，则none周末不着色。默认值：weekend background=none。
里程碑线是一个标志。没有参数时，true将绘制里程碑线。有时，false将不绘制线条。可以为整个图表和单个里程碑提供此选项。可以为里程碑本地更改此设置。里程碑线可能会被今天的线条覆盖。默认值：milestone line=false。
里程碑线条风格设置里程碑线的样式。只能为整个图表设置，不能为单个里程碑设置。默认值：milestone line style/.style={blue,thick}。

以下代码进行了修补pgfgantt，以使新代码在正确的时间执行。但这意味着，该代码可能无法与旧版本或新版本兼容pgfgantt（此处使用的当前版本：2013/06/01 v4.0）。
