p:带有DateTime轴的图表

Question

我正在尝试使用<p:chart>Primefaces 5.1 的组件创建折线图.

我需要X轴显示时间.像这样的东西:

但只针对旧版本的文档.

我发现了几件事:

• 自定义primefaces图表
• http://forum.primefaces.org/viewtopic.php?f=3&t=23891&p=78637#p78637

但是在5.1版本中没有这样的标签<p:lineChart>,甚至没有属性extender="".

我根据展示创建了我的图表:

• http://www.primefaces.org/showcase/ui/chart/date.xhtml

但这个例子并没有多大帮助,因为它只适用于日期.并且复杂化为String.我需要时间.

我想知道是否有人已经在较新版本的Primefaces中创建了类似的东西.

编辑:

再搜索一下,我找到了这个主题:

• http://forum.primefaces.org/viewtopic.php?f=16&t=40301&p=127330&hilit=p%3Achart+date#p127330

我使用了它提到的例子,我可以使它工作.

我可以看到,当它是DateAxis时需要设置axis.setMax().最后看起来像这样:

它按我的需要工作,但有两件事我不明白:

第一:需要设置的原因axis.setMax().

第二:这个模式用的是axis.setTickFormat("%H:%#M:%S")什么？

Answer 1

好吧,我想现在我找到了一个可以接受的解决方案

图表的最初问题是axis.setMax().

而使用的模式axis.setTickFormat是:
