英文:
add labels and legend in plotly express in streamlit
问题
来自plotly.subplots的make_subplotsimport plotly.graph_objects as goimport 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_subplotsimport plotly.graph_objects as goimport plotly.express as pximport streamlit as st#index is datefig1 = 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=2st.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 subplotsfig.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 labelstitle_text="Subplot 1"xaxis1_title="x-axis Title"yaxis1_text="y-axis Title"# Set legend for first subplotlegend_title="Set legend Title",legend_traceorder="normal",legend_x=0.1,legend_y=1.0,# Set axis labels and title for second subplotxaxis2_title="x-axis Title",yaxis2_title="y-axis Title",# set legend for second subplotlegend2_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)
