使用了Plotly库来创建一个数据可视化图表,并使用滑块来控制显示哪些数据
import plotly.graph_objects as go
from plotly.subplots import make_subplots
# 示例数据
x = [1, 2, 3, 4, 5]
y1 = [1, 2, 3, 4, 5]
y2 = [5, 4, 3, 2, 1]
y3 = [2, 3, 1, 5, 4]
# 创建子图
fig = make_subplots(rows=1, cols=1)
# 添加初始数据
fig.add_trace(
go.Scatter(x=x, y=y1, name="Data 1", visible=True),
row=1, col=1
)
fig.add_trace(
go.Scatter(x=x, y=y2, name="Data 2", visible=False),
row=1, col=1
)
fig.add_trace(
go.Scatter(x=x, y=y3, name="Data 3", visible=False),
row=1, col=1
)
# 创建滑块
steps = []
for i, y in enumerate([y1, y2, y3]):
step = dict(
method="update",
args=[{"visible": [False] * 3}, {"title": "Data {}".format(i+1)}],
label="Data {}".format(i+1)
)
step["args"][0]["visible"] = [False] * 3
step["args"][0]["visible"][i] = True
steps.append(step)
sliders = [dict(
active=0,
currentvalue={"prefix": "Show: "},
steps=steps
)]
# 更新布局
fig.update_layout(
sliders=sliders,
title="Data Visualization"
)
# 显示图表
fig.show()
