bokeh.models.callbacks¶

Client-side interactivity.

class Callback(**kwargs)¶

Bases: bokeh.plot_object.PlotObject

Base class for interactive callback. Callback is generally not useful to instantiate on its own.

  {
    "attributes": {
      "doc": null,
      "id": "7167a61f-ce6d-47c5-8623-bd47718a783b",

  }
]

class CustomJS(**kwargs)¶

Bases: bokeh.models.callbacks.Callback

Execute a JavaScript function.

args¶

property type: Dict(String, Instance(PlotObject))

A mapping of names to Bokeh plot obejcts. These objects are made available to the callback code snippet as the values of named parameters to the callback.

code¶

property type: String

A snippet of JavaScript code to execute in the browser. The code is made into the body of a function, and all of of the named objects in args are available as parameters that the code can use. Additionally, a cb_obj parameter contains the object that triggered the callback and an optional cb_data parameter that contains any tool-specific data (i.e. mouse coordinates and hovered glyph indices for the HoverTool).
