如何防止在具有时间刻度的图表中切断第一个/最后一个条形
gle*_*-84 14 momentjs chart.js
如何防止第一个和最后一个条被切断(显示一半)？
我需要在x轴上显示短月份名称.我尝试过使用各种最小/最大设置,但我似乎无法正确使用它.

var ctx = document.getElementById("myChart");

有一个名为offset的设置似乎对我有用:
xAxes: [{
offset: true
}]

- 你是对的。试试 `xAxes: [{offset: true}]` 可以在这里找到：http://www.chartjs.org/docs/latest/axes/cartesian/ 在第一个图表中 (2认同)
- 谢谢，偏移量肯定有效，但对我来说，它添加了过大的填充，看起来很糟糕。我找不到任何关于如何配置其大小的方法。我最终将虚拟（空）数据添加到数据集的最后位置，解决了这个问题。我的图表包含数百个条形图，如果您只有几个条形图，这可能无法使用 (2认同)
