How to synchronize document object with visualization in the browser ?

Hi,

I am now using the 0.11 server (bokeh serve). I have a callback on a TextInput widget and change the document object of that session in this callback function. But the change didn’t show up in the browser. Is there a way to populate the change on document in bokeh serve to the visualization in the browser ?

Thanks a lot

Hi,

Much more information and specifics (e.g what any how exactly you are running, and example code) are needed in order to try and help.

Thanks,

Bryan

Hi Van de ven,

thanks a lot for the response. the code is

example.py

region = pd.read_csv(“region.csv”, encoding=“utf-8”).set_index(“plo_region”)

TS_LENGTH=360

fig = figure(plot_width=700, plot_height=500, y_axis_type=“log”,y_range=(10**-2, 10**3))

callback template

def callback_template(new, table, ts_length):

whatever behavior

def callback_region(attr, old, new):

callback_template(new, region, TS_LENGTH)

what to add line in callback function

curdoc().clear()

fig.line(x=[1,2,3], y=[1,2,3], legend=“sdfds”,color=“black”)

curdoc().add_root(hplot(inputs, fig))

textInput_region = TextInput(value=“”, title=“region:”)

textInput_region.on_change(“value”, callback_region)

controls = [textInput_region]

inputs = HBox(VBoxForm(controls), width=300)

put the button and plot in a layout and add to the document

curdoc().add_root(hplot(inputs, fig))

I start the server with

bokeh serve example.py
