YouĬan see this output in your browser’s JavaScript console log. Many of theĮxamples produce print output using the JavaScript console.log function. The sections below are examples for all widgets available in Bokeh. In this section, we shall see how to add Bokeh widgets and assign JavaScript callbacks. Use Bokeh server and set up event handlers. See UI elements supporting tooltips for more information about adding Bokeh allows call back functionality to be defined with two methods Use the CustomJS callback so that the interactivity will work in standalone HTML documents. Hover over the question mark icon next to “Choose values” to see the tooltip. Information about the widget’s purpose or use, for example. This can be helpful to provide additional This allows you to use callbacksĪdditionally, since the visualization itself is displayed in a browser, you If you want to use widgets in connection with a Bokeh server, the serverĬan handle some interactivity.
