Change the RadioButtonGroup values based on Select widget

Community Support

Hello,

Is it possible to change the RadioButtonGroup values based on Select widget in Bokeh?

Thanks

Yes, you can do this by assigning a new value to the attribute you wish to change within a callback. Using bokeh server, one such callback could look like this:

def myCallback(attr, old, new):
    myRbgWidget.labels = newLabels
mySelectWidget.on_change('value', myCallback)

Using a javascript callback it might look like this:

cb = CustomJS(args=dict(myRgbWidget=myRgbWidget, newLabels=newLabels), code=    '''
myRgbWidget.labels = newLabels;
'''
)
mySelectWidget.js_on_change('value', cb)

If you aren’t familiar with callbacks, the tutorial notebooks on Bokeh Apps and Adding Interactions should help you put these snippets in context.

Hi Tyler,

Do you mind providing a small example of it?

Thank you,

No problem, here’s a working example using Bokeh Server

from [bokeh.io](http://bokeh.io) import curdoc
from bokeh.layouts import row
from bokeh.models.widgets import Select, RadioButtonGroup
select = Select(options=['foo', 'bar'], value='foo'
)
newLabels = {
'foo': ['foobar', 'foobaz'    ],
'bar': ['barfoo', 'barbaz'
]
}
radio = RadioButtonGroup(labels=newLabels['foo'
])
layout = row(select, radio)
def callback(attr, old, new):
    radio.labels = newLabels[select.value]
select.on_change('value'
, callback)
curdoc().add_root(layout)
