Plotly FigureWidget 概述

Plotly FigureWidget 概述#

参考：Plotly FigureWidget Overview | Python | Plotly

创建一个简单的 FigureWidget#

创建一个空的 FigureWidget，然后查看它。

import plotly.graph_objects as go

f = go.FigureWidget()
f

添加轨迹或更新布局，然后观察上面的输出实时更新。

f.add_scatter(y=[2, 1, 4, 3]);

f.add_bar(y=[1, 4, 3, 2]);

f.layout.title = 'Hello FigureWidget'

更新数据和布局#

# update scatter data
scatter = f.data[0]
scatter.y = [3, 1, 4, 3]

# update bar data
bar = f.data[1]
bar.y = [5, 3, 2, 8]

f.layout.title.text = 'This is a new title'

从 Figure graph object 构建 FigureWidget#

标准的 Figure 对象可以传递给 FigureWidget 构造函数。

import plotly.graph_objects as go

trace = go.Heatmap(z=[[1, 20, 30, 50, 1], [20, 1, 60, 80, 30], [30, 60, 1, -10, 20]],
                   x=['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday'],
                   y=['Morning', 'Afternoon', 'Evening'])
data=[trace]
layout = go.Layout(title='Activity Heatmap')

figure = go.Figure(data=data, layout=layout)

f2 = go.FigureWidget(figure)
f2
