can I change figure's para in update?

I created interactive bar by rect, due to my different x_axis, I wish to change my figure’s x_range, so to change the bar’s x_axis name.
Here are some of my codes:

xis_map = {

“Current Location”:location,

#‘Current Company’:‘company’,

“Current Industry”:industry,

“Current Company”:company

}

y_map ={

“Current Location”:local_counts1,

“Current Industry”:industry_counts1

}

height_map={

“Current Location”:y_local_height,

“Current Industry”:y_indus_height,

“Current Company”:y_company_height

}

cities=TextInput(title=‘location name’)

x_axis=Select(title=‘X axis’,options=sorted(axis_map.keys()),value=‘Current Industry’)

source = ColumnDataSource(data=dict(x=,y=,height=,x_range_name=))

plot = figure(plot_height=600, plot_width=800, title="", toolbar_location=None, tools=[hover],x_range=axis_map[x_axis.value],y_range=[0,2000])

plot.rect(x=‘x’,y=‘y’,width=.8,height=‘height’,source=source)

#Callback_Age = CustomJS(args={’’})

def update():

plot.xaxis.axis_label=x_axis.value

plot.yaxis.axis_label=‘numbers’

source.data=dict(

x=axis_map[x_axis.value],

y=height_map[x_axis.value],

height=height_map[x_axis.value]*2.0,

x_range_name=axis_map[x_axis.value]

)

#bokeh.plotting.curplot().x_range=axis_map[x_axis.value]

def input_change(attrname,old,new):

update()

controls=[cities,x_axis]

for control in controls:

control.on_change('value',input_change)

inputs=HBox(VBoxForm(*controls))

input_change(None,None,None)

curdoc().add_root(HBox(inputs,plot))

in the line plot=figure,the value of x_range will be the value of my x_axis, I want to change it every time I update my data.

is there any solution?

Hi,

There are two different kinds of callbacks, and it is important to keep the distinction in mind:

* CustomJS -- these run *javascip code* and only execute *in the browser* No "real" python code is possible here

* Bokeh server -- these are python funcs, passed to .on_change and execute actual python code *on the server*

It's hard to give any concrete advice without knowing more about what you are actually trying to accomplish.

There are numerous examples you can study, however. There is information and examples of CustomJS callbacks here:

  http://bokeh.pydata.org/en/latest/docs/user_guide/interaction.html#javascript-callbacks

And there are various example of using the server and server callbacks here:

  https://github.com/bokeh/bokeh/tree/0.11.1/examples/app

Note: I've referenced the GitHub repo at the latest stable release tag, 0.11.1

Thanks,

Bryan

I will try CustomJS
and if you don’t mind:

here:

plot = figure(plot_height=600, plot_width=800, title=“”, toolbar_location=None, tools=[hover],x_range=axis_map[x_axis.value],y_range=[0,2000])

plot.rect(x=‘x’,y=‘y’,width=.8,height=‘height’,source=source)

I hope I could change the figure’s x_range data in every update, is it possible in CustomJS?

is there any where I can check figure’s **parameters, the x_range and y_range, in the official document, I can’t see it ,**only rect and others can be seen.
