如何将PlantUML甘特图里程碑文本置于菱形左侧？

可以实现这个需求，PlantUML甘特图支持通过left关键字指定里程碑文本显示在图形左侧，直接修改代码即可：

@startgantt
[Prototype design] lasts 1 weeks
then [Prototype completed]  lasts 4 days
[End Prototype completed] happens at [Prototype completed]'s end
then [Test prototype] lasts 5 days
[End Test prototype] happens at [Test prototype]'s end left

[Prototype completed] is deleted
[End Prototype completed] is deleted
@endgantt

只需在目标里程碑的定义末尾添加left关键字，就能让“End Test prototype”文本显示在最后一个菱形里程碑的左侧，从而缩减甘特图的横向宽度，提升可读性。
