条形图 - 自定义Y轴

Question

我有一个需要完全自定义的y轴的要求。我想在条形图的y轴上显示时钟的"小时"。

但要求是，我的y轴应从> 19,20,21,22,23,24,01,02,02,03,04,04,05,06,07,07,08,09,1011，12,13,14,15,16,17,18

这就是我希望我的y轴范围看起来像。

我尝试使用"范围：[a-b]"选项，但它以升序顺序自动对数字进行自动分类。

ps：我正在使用Plotly，但是如果有其他图表框架可以置于目的，我会选择它。

Answer 1

在Plotly中您可以执行以下操作：

• 将您的Y值放在text属性中
• 调整您的Y值，即19等于0，24等于5等。
• 使用tickvals给出从0到23的范围，但使用ticktext将其标记为'19'至'18'
• 将tickmode设置为array，以确保ticktext和tickvals实际上读取
• 将xaxis range调整为[-0.5, 23.5]
