我在这里遇到的问题是如何将y轴更改为高于9的值，x轴值只有男性和女性没有国家值，为x添加线-axis，因为x轴上没有任何线条，最后，将文本锚点移动到x轴的右侧。

[{"countryName":"Afghanistan","gender":"Female","deaths":"97"},{"countryName":"Afghanistan","gender":"Male","deaths":"108"}]

以上是我使用过的JSON文件。这是我创建的图表的屏幕截图。 http://i.stack.imgur.com/B3Zbr.jpg

我认为没有显示x轴线，因为你的css中有.x.axis path {display: none;}。

This似乎回答了如何设置刻度轴名称。

如何更改图形的x轴和y轴的属性以及轴的文本锚点？
