Hi everyone, I have two unsolid thoughts, where I need some confirmation/help:
The solution is to get the value of the widget in the Python layer is the Bokeh server approach.
Thank You, and have a nice day!
Additional information: (not necessary to read)
I am a new in Bokeh.
I would like to use Bokeh for modeling with widgets.
I currently tried the Standalone version of Bokeh with Jupyter notebook.
My goal is to get the values of the widgets on the Python layer, so for example:
import pandas as pd import datetime as dt from bokeh.plotting import figure, show, ColumnDataSource from bokeh.io import output_notebook from bokeh.models import BoxSelectTool, HoverTool, RangeSlider, RadioGroup, CustomJS from bokeh.models.widgets import Select from bokeh.models.callbacks import CustomJS import numpy as np from bokeh.layouts import column, row select = Select(title="Features", value="SpO2", options=["SpO2", "HRV", "Cpnn", "CMCardiacEjectionTime", "CMBottomToPeakTime"]) def callback(value): select.value = value select.js_on_change("value", callback)
so then if I choose another value from the dropdown eg: Cpnn, I can use this value in the Python code, and not just in the JS layer as:
select.js_on_change('value', CustomJS(args=dict(select=select), code=""" console.log(this.value); var select = select select.value = this.value; select.change.emit() alert(select.value) """ ))
I want to use JS event listeners on widgets to call Python functions with their values.
Any help is greatly appreciated!
