如何在 Plotly 中旋转绘图的轴? [英] How do you rotate the axis of a plot in Plotly?

问题描述

我在 Plotly 中完成了以下绘图

I have the following plot done in Plotly

如您所见，X、Y 轴采用传统方式.如何旋转轴，以便垂直绘制 X，水平绘制 Y(向左)?

As you can see the X,Y axis are in the traditional way. How can I rotate the axis so that X is plot vertically and Y horizontally (to the left)?

(我也想修改每个轴的距离和间距)

(also I would like to modify the reach and separations of each axis)

我想它必须对布局元素做些什么.

I suppose it has to do something with the layout element.

如果到目前为止我的代码

My code if so far

layout= go.Layout(title=go.layout.Title(text=title,x=0.5),
        xaxis={'title':'x[m]'},
        yaxis={'title':'y[m]'})

    point_plot=[
            go.Scatter(x=[series[listoflabels[0]]],y=[series[listoflabels[1]]],name="V0"),
            go.Scatter(x=[series[listoflabels[2]]],y=[series[listoflabels[3]]],name="GT"),
            go.Scatter(x=[0],y=[0],name="egoCar")
            ]

    return go.Figure(data=point_plot, layout=layout)

为了使其可重现，我将代码修改为

In order to make it reproducible I modified the code to

layout1= go.Layout(title=go.layout.Title(text="A graph",x=0.5),
        xaxis={'title':'x[m]'},
        yaxis={'title':'y[m]'})

point_plot=[
            go.Scatter(x=[3],y=[1],name="V0"),
            go.Scatter(x=[5],y=[2],name="GT"),
            go.Scatter(x=[0],y=[0],name="egoCar")
    ]
            
go.Figure(data=point_plot, layout=layout1).show()

推荐答案

我不知道 Plotly 有任何内置方法来切换 x 轴和 y 轴.但是，您可以自己实现这一点，只需切换 x 轴和 y 轴的标题，然后切换与您的点相对应的参数 x 和 y.

I am not aware that Plotly has any built-in method to switch x- and y-axes. However, you can achieve this yourself but switching the titles of the x- and y-axes, then switching the parameters x and y that correspond to your points.

然后您可以将 y 轴(包含您的 x 坐标)放在布局的右侧，并反转 x 轴(包含您的 y 坐标)的范围，使原点位于下方-右侧.

Then you can place the y-axis (containing your x-coordinates) on the right side in your layout, and reverse the range of the x-axis (containing your y-coordinates) so that the origin is in the lower-right side.

import plotly.graph_objects as go

# switch the axes titles
layout1= go.Layout(title=go.layout.Title(text="A graph",x=0.5),
        xaxis={'title':'y[m]'},
        yaxis={'title':'x[m]', 'side':'right'})

# switch the x- and y-coordinates
point_plot=[
            go.Scatter(y=[3],x=[1],name="V0"),
            go.Scatter(y=[5],x=[2],name="GT"),
            go.Scatter(y=[0],x=[0],name="egoCar")
    ]


fig = go.Figure(data=point_plot, layout=layout1)

# reverse the range of the xaxis (which contains the y values)
fig.update_xaxes(autorange="reversed")
fig.show()
