如何在使用plotly进行子绘图时隐藏X轴值

Question

我正在使用plotly来绘制一个大的csv文件（包含大量数据）和一些图表的子绘图。 问题是，对于每个图表，我得到了x轴上每个点的所有日期和时间，这导致图表质量不好。我怎样才能在前5张图表中隐藏x轴的值，而在最后一张图表中保留它，以便更好地查看图表？在

这是我的代码：有问题的部分从第125行开始

Answer 1

我从安德鲁斯的评论开始。但相关来源是this one：

trace0 = go.Scatter(
  x = [0,1,1,0,0,1,1,2,2,3,3,2,2,3],
  y = [0,0,1,1,3,3,2,2,3,3,1,1,0,0]
)

trace1 = go.Scatter(
  x = [0,1,2,3],
  y = [1,2,4,8],
  yaxis = "y2"
)

layout = go.Layout(
    width = 800,
    height = 500,
    title = "fixed-ratio axes",
    xaxis = dict(
      nticks = 10,
      domain = [0, 0.45],
      title = "shared X axis"
    ),
    yaxis = dict(
      scaleanchor = "x",
      domain = [0, 0.45],
      title = "1:1"
    ),
    yaxis2 = dict(
      scaleanchor = "x",
      scaleratio = 0.2,
      domain = [0.55,1],
      title = "1:5"
    ))

说明

您需要定义一次xaxis。对于每个其他子批，您设置scaleanchor = "x"，以便每个子批共享相同的xaxis。所有共享一个xasis的绘图都会自动绘制为子图，因此您可以去掉当前的结构。在
