Plotly-express-19-plotly中设置图形大小

本文中介绍的是如何在plotly中通过两种方法来设置图形的大小

px实现
go.Figure实现

px实现

数据

数据使用的是px中自带的tips数据集

import plotly.express as px

df = px.data.tips()
df

绘图

fig = px.scatter(df, x="total_bill", y="tip", facet_col="sex",facet_row="smoker",  # 横纵坐标的参考属性
                 width=1000, height=600)

fig.update_layout(
    margin=dict(l=20, r=20, t=20, b=20),  # 上下左右的边距大小
    paper_bgcolor="dodgerblue",  # 颜色
)

fig.show()

go.Figure实现

数据

import plotly.graph_objects as go

fig = go.Figure()

fig.add_trace(go.Scatter(
    x=[0, 1, 2, 3, 4, 5, 6, 7, 8],
    y=[0, 1, 2, 3, 4, 5, 6, 7, 8]
))

fig.update_layout(
    autosize=False,
    width=800,
    height=800,
    margin=dict(
        l=50,
        r=50,
        b=100,
        t=100,
        pad=9
    ),
    paper_bgcolor="mediumaquamarine",
)

fig.show()

第二个案例

import plotly.graph_objects as go


fig = go.Figure()

fig.add_trace(go.Bar(
    x=["Apples", "Oranges", "Watermelon", "Pears"],
    y=[3, 2, 1, 4]
))

fig.update_layout(
    autosize=False,
    width=1000,
    height=800,
    yaxis=dict(
        title_text="Y-axis Title",
        ticktext=["Very long label", "long label", "3", "label"],
        tickvals=[1, 2, 3, 4],
        tickmode="array",
        titlefont=dict(size=50),
    )
)

fig.update_yaxes(automargin=True)  # Y-axis Title自动移到左边合适的位置

fig.show()
