我正在使用plotly scatter3d绘制2条轨迹，我为每个轴修改了布局范围，设置了图形的宽度和高度，将自动量程和自动缩放设置为False，但是当我删除轨迹时，3D绘图的比例会发生变化 . 如何修复它以便我可以看到一条迹线消失而另一条痕迹保留在原位？

X = np.random.random_sample((10, 3))
Y = np.random.random_sample((10, 3))

trace1 = go.Scatter3d(x=X[:,0],y=X[:,1], z=X[:,2],)
trace2 = go.Scatter3d(x=Y[:,0],y=Y[:,1], z=Y[:,2],)

data = [trace1,trace2]
layout = go.Layout(autosize=False,
                   scene=dict(xaxis = dict(autorange = False, range = [0,1],),
                              yaxis = dict(autorange = False, range = [0,1],),
                              zaxis = dict(autorange = False, range = [0,1],),),)

fig = go.Figure(data=data, layout=layout)
plotly.offline.iplot(fig)
