删除 Plotly 平行坐标图末端的刻度标签

Question

我想删除在这个平行坐标图中圈出的数字：

生成此图的代码（取自Plotly Express example）：

import plotly.express as px
df = px.data.iris()
fig = px.parallel_coordinates(df, color="species_id", labels={"species_id": "Species",
                "sepal_width": "Sepal Width", "sepal_length": "Sepal Length",
                "petal_width": "Petal Width", "petal_length": "Petal Length", },
                             color_continuous_scale=px.colors.diverging.Tealrose,
                             color_continuous_midpoint=2)
fig.show()

我试着查看 ticks 的文档，但我无法弄明白。我是 Plotly 的新手。

Answer 1

明确定义 tickvals https://plotly.com/python/reference/parcoords/
使用以下代码构建图形后有更新痕迹
图像显示之前和之后

import plotly.express as px
import numpy as np

df = px.data.iris()
fig = px.parallel_coordinates(
    df,
    color="species_id",
    labels={
        "species_id": "Species",
        "sepal_width": "Sepal Width",
        "sepal_length": "Sepal Length",
        "petal_width": "Petal Width",
        "petal_length": "Petal Length",
    },
    color_continuous_scale=px.colors.diverging.Tealrose,
    color_continuous_midpoint=2,
)
fig.show()
fig.update_traces(
    dimensions=[
        {**d, **{"tickvals": np.linspace(min(d["values"]), max(d["values"]), 5)}}
        for d in fig.to_dict()["data"][0]["dimensions"]
    ]
)
