在 plotly 散点图中按下按钮时更新轴

Question

我有几个数字列表，我想以成对的方式进行比较。我尝试使用 Plotly 制作散点图并添加按钮我希望能够更改 x 或 y 轴上的列表。

使用 example in the documentation，我设法创建了绘图和按钮。但是，当我 select 另一个列表时，轴不会更新。

这是我的代码示例：

import plotly
from plotly import graph_objs as go, offline as po, tools
po.init_notebook_mode()

import numpy as np

l1 = list(np.random.randint(100, size=100))
l2 = list(np.random.rand(100))
l3 = list(np.random.randint(100, size=100))

# Create figure
fig = go.Figure()

# Add scatter
fig.add_trace(go.Scatter(
     x=l1,
     y=l1,
    mode = 'markers'
)
             )

# Add drowdowns
button_layer_1_height = 1.15
fig.update_layout(
    updatemenus=[
        go.layout.Updatemenu(
            buttons=list([
                dict(
                    args=["x", l1],
                    label="L1",
                    method="restyle"
                ),
                dict(
                    args=["x", l2],
                    label="L2",
                    method="restyle"
                ),
                dict(
                    args=["x", l3],
                    label="L3",
                    method="restyle"
                ),
            ]),
            direction="down",
            pad={"r": 10, "t": 10},
            showactive=True,
            x=0.02,
            xanchor="left",
            y=button_layer_1_height,
            yanchor="top"
        ),
        go.layout.Updatemenu(
            buttons=list([
                dict(
                    args=["y", l1],
                    label="L1",
                    method="restyle"
                ),
                dict(
                    args=["y", l2],
                    label="L2",
                    method="restyle"
                ),
                dict(
                    args=["y", l3],
                    label="L3",
                    method="restyle"
                ), 
            ]),
            direction="down",
            pad={"r": 10, "t": 10},
            showactive=True,
            x=0.15,
            xanchor="left",
            y=button_layer_1_height,
            yanchor="top"
        ),
    ]
)

fig.update_layout(
    annotations=[
        go.layout.Annotation(text="x", x=0, xref="paper", y=1.08, yref="paper",
                             align="left", showarrow=False),
        go.layout.Annotation(text="y", x=0.13, xref="paper", y=1.08,
                             yref="paper", showarrow=False),
    ])

fig.show()

Answer 1

在 args 中，您的列表（例如 L1）需要是列表的 en 元素，而不仅仅是列表本身。因此，只需将所有 args=["x", l1] 更改为 args=["x", [l1]] 即可！听起来好得令人难以置信？这里有一些证据

先画图运行:

选择 L2 时绘制 x:

为 y 选择 L3 时绘制：

这是您编辑的代码：

import plotly
from plotly import graph_objs as go, offline as po, tools
po.init_notebook_mode()

import numpy as np

l1 = list(np.random.randint(100, size=100))
l2 = list(np.random.rand(100))
l3 = list(np.random.randint(100, size=100))

# Create figure
fig = go.Figure()

# Add scatter
fig.add_trace(go.Scatter(
     x=l1,
     y=l1,
    mode = 'markers'
)
             )

# Add drowdowns
button_layer_1_height = 1.15
fig.update_layout(
    updatemenus=[
        go.layout.Updatemenu(
            buttons=list([
                dict(
                    args=["x", [l1]],
                    label="L1",
                    method="restyle"
                ),
                dict(
                    args=["x", [l2]],
                    label="L2",
                    method="restyle"
                ),
                dict(
                    args=["x", [l3]],
                    label="L3",
                    method="restyle"
                ),
            ]),
            direction="down",
            pad={"r": 10, "t": 10},
            showactive=True,
            x=0.02,
            xanchor="left",
            y=button_layer_1_height,
            yanchor="top"
        ),
        go.layout.Updatemenu(
            buttons=list([
                dict(
                    args=["y", [l1]],
                    label="L1",
                    method="restyle"
                ),
                dict(
                    args=["y", [l2]],
                    label="L2",
                    method="restyle"
                ),
                dict(
                    args=["y", [l3]],
                    label="L3",
                    method="restyle"
                ), 
            ]),
            direction="down",
            pad={"r": 10, "t": 10},
            showactive=True,
            x=0.15,
            xanchor="left",
            y=button_layer_1_height,
            yanchor="top"
        ),
    ]
)

fig.update_layout(
    annotations=[
        go.layout.Annotation(text="x", x=0, xref="paper", y=1.08, yref="paper",
                             align="left", showarrow=False),
        go.layout.Annotation(text="y", x=0.13, xref="paper", y=1.08,
                             yref="paper", showarrow=False),
    ])

fig.show()
