如何在绘制多条图的同时绘制python的x_Axis范围

问题描述 投票：1回答：2

我实际上是试图用一个x_axis绘制多条迹线。

我用于绘图的代码是：

import plotly.graph_objects  as go
import datetime
import numpy
x1= numpy.array([datetime.time(4, 45), datetime.time(5, 15), datetime.time(5, 30),datetime.time(5, 45), datetime.time(6, 0), datetime.time(6, 15),
       datetime.time(6, 30), datetime.time(6, 45), datetime.time(7, 0),datetime.time(7, 15), datetime.time(7, 30), datetime.time(7, 45),
       datetime.time(8, 0), datetime.time(8, 15), datetime.time(8, 30),datetime.time(8, 45), datetime.time(9, 0), datetime.time(9, 15),
       datetime.time(9, 30), datetime.time(9, 45), datetime.time(10, 0),datetime.time(10, 15), datetime.time(10, 30),datetime.time(10, 45), datetime.time(11, 0), datetime.time(11, 15),datetime.time(11, 30), datetime.time(11, 45), datetime.time(12, 0),
       datetime.time(12, 15), datetime.time(12, 30),datetime.time(12, 45), datetime.time(13, 0), datetime.time(13, 15),datetime.time(13, 30), datetime.time(13, 45), datetime.time(14, 0),datetime.time(14, 15), datetime.time(14, 30),datetime.time(14, 45), datetime.time(15, 0), datetime.time(15, 15),datetime.time(15, 30), datetime.time(15, 45), datetime.time(16, 0),datetime.time(16, 15), datetime.time(16, 30),
       datetime.time(16, 45), datetime.time(17, 0), datetime.time(17, 15),datetime.time(17, 30), datetime.time(17, 45), datetime.time(18, 0),
       datetime.time(18, 15), datetime.time(18, 30),datetime.time(18, 45), datetime.time(19, 0), datetime.time(19, 15),datetime.time(19, 30), datetime.time(19, 45), datetime.time(20, 0),datetime.time(20, 15), datetime.time(20, 30),

x2 = numpy.array(
    [datetime.time(0, 15), datetime.time(4, 45), datetime.time(5, 15),datetime.time(5, 30), datetime.time(5, 45), datetime.time(6, 0),datetime.time(6, 15), datetime.time(6, 30), datetime.time(6, 45),datetime.time(7, 0), datetime.time(7, 15), datetime.time(7, 30),

y2 = numpy.array([  1.,  16.,  15.,   7.,  27.,  27.,  86.,  39.,  92., 157., 257.,
       278., 253., 273., 217., 200.,  94.,  86.,  54.,  42.,  24.,  37.,34.,  38.,  34.,  35.,  26.,  51.,  29.,  35.,  30.,  62.,  27.,30.,  19.,  19.,  24.,  23.,  19.,  16.,  13.,  33.,  36.,  20.,

fig = go.Figure(data=[
    go.Scatter(
        x= x1,
        y= y1,
        mode = 'markers'
            ),
go.Scatter(
        x= x2,
        y= y2,
    mode = 'markers'
    )])
fig.show()

图：

您可以从图中看到，结果给出了一个奇怪的行为，而我的两条迹线都是从datetime.time（4，45）开始的，情况并非如此。注意我的x_Axis范围是变化的，我认为这是主要问题，实际上，我有多个示例数据，其中x_axis是datetime.time，其中每个示例数据（Xn，Yn）都有自己的间隔和值的长度，但是我知道我的x_axis值的间隔为以15分钟为步长，以datetime.time（0,0）作为最小值，以datetime.time（23,45）作为最大值。

因此，我的x1，x2…，xn中的每个都在此时间间隔中获取值，因此我想用此全局时间间隔（在下一个代码中称为range_data）修复x_axis，然后绘制任何示例数据在它上面。

range_data = pd.DataFrame()
range_data['range_data'] = pd.date_range("00:00", "23:45", freq="15min").time
range_data = range_data.set_index('range_data')

谢谢，

我不确定为什么会发生这种情况，但我有一个解决方案。原因之一似乎是您的x变量的长度不同。而且，如果您仔细查看您的绘图，您会发现在通过单击图例中的名称选择其中的一条时，两条线都显示得很好。 可能有一个或多个错误的时间戳，但我一直找不到。那么，解决方案是什么？在pandas数据框中组织数据，执行outer连接，并使用'ffill'和[>]插入缺失值
