st.bokeh_chart

显示互动式虚化图。

Bokeh 是 Python 的一个图表库。此函数的参数与 Bokeh 的 show 函数的参数非常接近。有关 Bokeh 的更多信息，请访问 https://bokeh.pydata.org。

要在 Streamlit 中显示 Bokeh 图表，请在调用 Bokeh 的 show 时调用 st.bokeh_chart。

Function signature[source]
st.bokeh_chart(figure, use_container_width=False)
Parameters
figure (bokeh.plotting.figure.Figure)	A Bokeh figure to plot.
use_container_width (bool)	Whether to override the figure's native width with the width of the parent container. If use_container_width is False (default), Streamlit sets the width of the chart to fit its contents according to the plotting library, up to the width of the parent container. If use_container_width is True, Streamlit sets the width of the figure to match the width of the parent container.

代码

import streamlit as st
from bokeh.plotting import figure

x = [1, 2, 3, 4, 5]
y = [6, 7, 2, 4, 5]

p = figure(
    title='simple line example',
    x_axis_label='x',
    y_axis_label='y')

p.line(x, y, legend_label='Trend', line_width=2)

st.bokeh_chart(p, use_container_width=True)

这段代码使用了Streamlit和Bokeh库来创建一个简单的折线图。首先，我们导入了streamlit和bokeh.plotting中的figure模块。然后，我们定义了x和y轴的数据点。接下来，我们创建了一个Bokeh图形对象p，并设置了标题、x轴标签和y轴标签。然后，我们使用p.line()方法在图形对象上绘制了折线，设置了图例标签和线宽。最后，我们使用st.bokeh_chart()方法将图形对象p显示在Streamlit应用程序中，并设置了use_container_width=True以适应容器的宽度。Bokeh

st.graphviz_chart 

使用 dagre-d3 库显示图表。

Function signature[source]
st.graphviz_chart(figure_or_dot, use_container_width=False)
Parameters
figure_or_dot (graphviz.dot.Graph, graphviz.dot.Digraph, str)	The Graphlib graph object or dot string to display
use_container_width (bool)	Whether to override the figure's native width with the width of the parent container. If use_container_width is False (default), Streamlit sets the width of the chart to fit its contents according to the plotting library, up to the width of the parent container. If use_container_width is True, Streamlit sets the width of the figure to match the width of the parent container.

代码

import streamlit as st
import graphviz

# Create a graphlib graph object
graph = graphviz.Digraph()
graph.edge('run', 'intr')
graph.edge('intr', 'runbl')
graph.edge('runbl', 'run')
graph.edge('run', 'kernel')
graph.edge('kernel', 'zombie')
graph.edge('kernel', 'sleep')
graph.edge('kernel', 'runmem')
graph.edge('sleep', 'swap')
graph.edge('swap', 'runswap')
graph.edge('runswap', 'new')
graph.edge('runswap', 'runmem')
graph.edge('new', 'runmem')
graph.edge('sleep', 'runmem')

st.graphviz_chart(graph)

这段代码使用了Streamlit和Graphviz库。首先，导入了streamlit和graphviz模块。然后创建了一个graphviz的有向图对象graph。接着，通过调用edge方法，向图中添加了一系列的边，构成了一个简单的图形结构。最后，使用st.graphviz_chart方法将图形显示在Streamlit应用程序中。整体来说，这段代码的作用是创建一个简单的有向图并在Streamlit应用程序中展示出来。或者，您也可以使用 GraphViz 的 Dot 语言从图形中渲染图表：

st.graphviz_chart('''
    digraph {
        run -> intr
        intr -> runbl
        runbl -> run
        run -> kernel
        kernel -> zombie
        kernel -> sleep
        kernel -> runmem
        sleep -> swap
        swap -> runswap
        runswap -> new
        runswap -> runmem
        new -> runmem
        sleep -> runmem
    }
''')

 st.plotly_chart

显示交互式 Plotly 图表。

Plotly 是 Python 的图表库。该函数的参数与 Plotly 的 plot() 函数的参数非常接近。

要在 Streamlit 中显示 Plotly 图表，请在调用 Plotly 的 py.plot 或 py.iplot 时调用 st.plotly_chart。

Function signature[source]
st.plotly_chart(figure_or_data, use_container_width=False, *, theme="streamlit", key=None, on_select="ignore", selection_mode=('points', 'box', 'lasso'), **kwargs)
Returns
(element or dict)	If on_select is "ignore" (default), this method returns an internal placeholder for the chart element. Otherwise, this method returns a dictionary-like object that supports both key and attribute notation. The attributes are described by the PlotlyState dictionary schema.
Parameters
figure_or_data (plotly.graph_objs.Figure, plotly.graph_objs.Data, or dict/list of plotly.graph_objs.Figure/Data)	The Plotly Figure or Data object to render. See Plotly Python Graphing Library for examples of graph descriptions.
use_container_width (bool)	Whether to override the figure's native width with the width of the parent container. If use_container_width is False (default), Streamlit sets the width of the chart to fit its contents according to the plotting library, up to the width of the parent container. If use_container_width is True, Streamlit sets the width of the figure to match the width of the parent container.
theme ("streamlit" or None)	The theme of the chart. If theme is "streamlit" (default), Streamlit uses its own design default. If theme is None, Streamlit falls back to the default behavior of the library.
key (str)	An optional string to use for giving this element a stable identity. If key is None (default), this element's ide
