我有13周的数据，我想显示为条形图。我要每周星期一开始日期。我已经设法得到了13个星期显示在xaxis和13条线显示。我不能让日期从星期一开始，并与酒吧排队。

当来自Flot的自动滴答生成器不符合您的要求时，您总是可以手动定义滴答(在这里，从数据中获取它们)：

代码语言：javascript
复制
var ticks = [];
for (var i = 0; i < datasets[0].data.length; i++) {
  ticks.push(datasets[0].data[i][0]);
}

在为条形图指定align: 'center'之后，条形线和x轴刻度线现在对齐。

PS:您的数据有14个数据点，而不是13个。我还调整了x轴的最大值，以便最后一个条是可见的。
