如何更改绘图热图中单元格的大小?我需要更大的细胞
import plotly.express as px
fig1 = px.imshow(df[col],color_continuous_scale='Greens')
fig1.layout.yaxis.type = 'category'
fig1.layout.xaxis.type = 'category'
fig1.layout.yaxis.tickmode = 'linear'
fig1.layout.xaxis.tickmode = 'linear'
fig1.layout.xaxis.tickangle = 65
fig1.layout.autosize = True
fig1.layout.height = 500
fig1.layout.width = 500
fig1.show()

结果(非常窄)
由于颜色条的原因,“px”可能不会使其成为正方形,那么为什么不使用“go”呢?
import plotly.graph_objects as go
fig = go.Figure(data=go.Heatmap(
z=[[1, 20, 30],
[20, 1, 60],
[30, 60, 1]]))
fig.show()

示例位于 px
import plotly.express as px
data=[[1, 25, 30, 50, 1], [20, 1, 60, 80, 30], [30, 60, 1, 5, 20]]
fig = px.imshow(data,
labels=dict(x="Day of Week", y="Time of Day", color="Productivity"),
x=['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday'],
y=['Morning', 'Afternoon', 'Evening']
)
fig.update_xaxes(side="top")
fig.layout.height = 500
fig.layout.width = 500
fig.show()

有点晚了,但如果您希望单元格更宽,请使用以下命令:
fig1 = px.imshow(df[col],color_continuous_scale='Greens', aspect='auto')

将方面参数设置为“auto”将使用非方形图块填充绘图区域。
