如何在用图进行子绘图时隐藏x轴值

时间：2019-05-27 21:28:24

标签： python pandas plotly

我正在使用plotly绘制一个较大的csv文件（包含大量数据）并在子图中按行绘制（实际上有效）一些图表。 问题在于，对于每个图表，我都获得了x轴上每个点的所有日期和时间，从而导致质量不好的图表。如何隐藏前五个图表的x轴值，同时保留最后一个图表的x轴，以更好地查看图表？

这是我的代码：有问题的部分从第125行开始

    fig = plotly.tools.make_subplots(rows=6, cols=1)

    fig.append_trace(temp1, 1, 1)
    fig.append_trace(temp2, 2, 1)
    fig.append_trace(temp3, 3, 1)
    fig.append_trace(Humidite, 4, 1)
    fig.append_trace(dioxyde_de_carbone, 5, 1)

    fig['layout'].update(title='Représentation graphique des données')
    plotly.offline.plot(fig, filename=str(DateDebut) +" a "+ str(DateFin) + ".csv", auto_open=True)

这就是我得到的：enter image description here

您可以使用以下两行对其进行修复：

fig.update_xaxes(showticklabels=False) # hide all the xticks
fig.update_xaxes(showticklabels=True, row=6, col=1)

我从安德鲁斯的评论开始。但是相关的来源是this one：

说明

您需要一次定义xaxis。为每个其他子图设置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" )) ，以便每个子图共享相同的scaleanchor = "x"。所有共享一个xasi的图都会自动绘制为子图，因此您可以摆脱当前的结构。

这里的其他答案是解决方法。通过shared_xaxes method中的make_subplots参数，Plotly提供您正在寻找的功能：

fig = plotly.subplots.make_subplots(rows=6, cols=1, shared_xaxes=True)

您还可以选择与shared_yaxes=True共享y轴。但是，如果要共享两个坐标轴，则可能会发现只绘制一个图并向其添加多条迹线比较容易（与使用子图相比）。
