Question

Bokeh演示展示了如何向滑块按钮添加回调 - http://bokeh.pydata.org/en/0.11.1/docs/user_guide/interaction.html#customjs-with-a-python-function

我正在尝试为单选按钮组创建类似的回调 -

radio_button_group = RadioButtonGroup(labels=["literacy", "economy", "health","household"], active=0,callback=CustomJS.from_py_func(callback) )

但上面的代码给出了错误 -

AttributeError: unexpected attribute 'callback' to RadioButtonGroup, possible attributes are active, disabled, labels, name, tags or type

Bokeh是否支持来自单选按钮组的回调，或者只能从滑块按钮进行回调，如文档中所示？

Answer 1

不同的小部件具有包含所选/突出显示的值的不同属性。对于RadioButtonGroup active，slider为value

您必须相应地更改callback功能

def callback(source=source):
    data = source.get('data')
    f = cb_obj.get('active')  # instead of 'value'
    x, y = data['x'], data['y']
    for i in range(len(x)):
        y[i] = Math.pow(x[i], f)
    source.trigger('change')
