Hi,

I am trying to change the options from a selection toolbox from a callback using the bokeh server.

My code:

from bokeh.io import curdoc

from bokeh.models import VBox, Select

def update(attrname, old, new):

var1 = select1.value

varA = int(var1) *5.0

varB = int(var1) *3.0

varC = int(var1) *8.0

newVar = [str(varA), str(varB), str(varC)]

select2.set(‘options’, newVar);

categories=[“1”,“2”,“3”]

select1 = Select(title=“Cat1”, value=categories[0], options=categories)

select1.on_change(‘value’, update)

select2 = Select(title=“Cat2”, value=“”)

layout = VBox(select1,select2)

#add to document

curdoc().add_root(layout)

my error:

set() takes 1 positional argument but 3 were given.

Could someone please tell me the correct way to do this?

Regards,

Rakesh

varA = int(var1) *5.0

varB = int(var1) *3.0

varC = int(var1) *8.0

newVar = [str(varA), str(varB), str(varC)]

select2.options = newVar

categories=[“1”,“2”,“3”]

        select1 = Select(title="Cat1", value=categories[0],

options=categories)

select1.on_change(‘value’, update)

select2 = Select(title=“Cat2”, value=“”)

layout = VBox(select1,select2)
