英文:
add labels and legend in plotly express in streamlit
问题
来自plotly.subplots的make_subplots
import plotly.graph_objects as go
import plotly.express as px
导入streamlit as st
#索引是日期
fig1 = px.line(plot_df2,y=['price','counting'],template="plotly_dark")
fig2 = px.line(plot_df3,y=['price','counting'],template="plotly_dark")
fig = make_subplots(rows=1, cols=2)
fig.add_trace(fig1['data'][0], row=1, col=1)
fig.add_trace(fig1['data'][1], row=1, col=1)
fig.add_trace(fig2['data'][0], row=1, col=2)
fig.add_trace(fig2['data'][1], row=1, col=2
# 在这里添加标签和图例
st.plotly_chart(fig, theme=None, use_container_width=True)
英文:
the following is my code:
from plotly.subplots import make_subplots
import plotly.graph_objects as go
import plotly.express as px
import streamlit as st
#index is date
fig1 = px.line(plot_df2,y=['price','counting'],template="plotly_dark"})
fig2 = px.line(plot_df3,y=['price','counting'],template="plotly_dark")
fig = make_subplots(rows=1, cols=2)
fig.add_trace(fig1['data'][0], row=1, col=1)
fig.add_trace(fig1['data'][1], row=1, col=1)
fig.add_trace(fig2['data'][0], row=1, col=2)
fig.add_trace(fig2['data'][1], row=1, col=2
st.plotly_chart(fig, theme=None, use_container_width=True)
i want to add labels like price and count and legend like 'the dataset plot' to the code how can i do it?
thanks in advance

# 使用 `update_layout` 可以实现这一点。这将在两个子图中添加标签和图例。
...
# 添加 traces 到子图中
fig.add_trace(fig1['data'][0], row=1, col=1, name='价格')
fig.add_trace(fig1['data'][1], row=1, col=1, name='计数')
fig.add_trace(fig2['data'][0], row=1, col=2, name='价格')
fig.add_trace(fig2['data'][1], row=1, col=2, name='计数')
fig.update_layout(
title= "设置标题",
xaxis_title="X轴标题",
yaxis_title="Y轴标题",
legend=dict(title="图例标题", traceorder="normal"),
# 设置第一个子图的标题和坐标轴标签
title_text="子图 1",
xaxis1_title="X轴标题",
yaxis1_text="Y轴标题",
# 为第一个子图设置图例
legend_title="设置图例标题",
legend_traceorder="normal",
legend_x=0.1,
legend_y=1.0,
# 设置第二个子图的坐标轴标签和标题
xaxis2_title="X轴标题",
yaxis2_title="Y轴标题",
# 为第二个子图设置图例
legend2_title="设置图例标题",
legend2_traceorder="normal",
legend2_x=0.1,
legend2_y=1.0,
)
st.plotly_chart(fig, theme=None, use_container_width=True)
英文:
You can accomplish that with the help of update_layout. This should add labels and legend to both subplots.
...
# Add traces to the subplots
fig.add_trace(fig1['data'][0], row=1, col=1, name='Price')
fig.add_trace(fig1['data'][1], row=1, col=1, name='Counting')
fig.add_trace(fig2['data'][0], row=1, col=2, name='Price')
fig.add_trace(fig2['data'][1], row=1, col=2, name='Counting')
fig.update_layout(
title= "Set Title",
xaxis_title="X-axis Title",
yaxis_title="Y-axis Title",
legend=dict(title="Legend Title", traceorder="normal"),
# Set first suplot title and axis labels
title_text="Subplot 1"
xaxis1_title="x-axis Title"
yaxis1_text="y-axis Title"
# Set legend for first subplot
legend_title="Set legend Title",
legend_traceorder="normal",
legend_x=0.1,
legend_y=1.0,
# Set axis labels and title for second subplot
xaxis2_title="x-axis Title",
yaxis2_title="y-axis Title",
# set legend for second subplot
legend2_title="Set legend Title",
legend2_traceorder="normal",
legend2_x=0.1,
legend2_y=1.0,
)
st.plotly_chart(fig, theme=None, use_container_width=True)
