原理: btn绑定一个函数callback ,在这个callback函数里更换图片对象的data_source 代码: from bokeh.models import ColumnDataSource,Button from bokeh.layouts import row from bokeh.plotting import figure, show,curdoc def callback(): global im urls=["""https://b-ssl.duitang.com/uploads/item/201604/...
'y',source=source)# 将图表添加到文档中curdoc().add_root(plot)# 定时更新数据curdoc().add_periodic_callback(update_data,1000)# 打开会话session.show()# 阻止脚本退出session.loop
让我们通过一个示例来演示如何使用 Bokeh Server 来实现实时数据更新: frombokeh.ioimportcurdocfrombokeh.plottingimportfigurefrombokeh.modelsimportColumnDataSourceimportnumpyasnp# 创建一个 ColumnDataSource 对象并存储数据x=np.linspace(0,10,1000)y=np.sin(x)source=ColumnDataSource(data=dict(x=x,y=y))#...
Python- Bokeh - DataCube -无法通过回调选择任何行和提取信息 在回调rxjava中返回Observable Bokeh server -在回调返回前强制刷新客户端图形? 在独立Bokeh plot中通过回调JS更改ColorMapper 在DataTable中选择行中的按钮 Python Bokeh,回调示例在浏览器中不起作用 ...
query_string 中的 server_path）发生改变后，将会触发这个 callback 运行，并且函数得到新的 pathname。
