Hi guys

I need the fonction vform to do some interactive plotting but i get this error:

ImportError Traceback (most recent call last)
in ()
----> 1 from bokeh.io import vform

ImportError: cannot import name ‘vform’

I don’t find any answer .So please if someone have the solution

Hi,

vform was deprecated and eventually removed: https://github.com/bokeh/bokeh/blob/342d55cf41579e3e551e204198d6a3ec39751315/sphinx/source/docs/releases/0.12.5.rst#deprecations-removed

I’m not sure what it’s function was. You should check the most recent Bokeh’s documents.

Regards,

Eugene

Hi,

You probably want "widgetbox" or "column" from bokeh.layouts

Thanks,

Bryan

Hi,

Tanks you .Here is the solution :

instead of vform you can use column → from bokeh.layouts import column

Here is an update example from bokeh tutorial

from bokeh.layouts import *
from bokeh.models import CustomJS, ColumnDataSource, Slider
from bokeh.plotting import figure, output_file, show
from bokeh.models.sources import ColumnDataSource
from bokeh.models.widgets import Button, DataTable, TableColumn
from bokeh.layouts import layout, widgetbox, column, row

output_file(“callback.html”)

x = [x*0.005 for x in range(0, 200)]
y = x

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

plot = figure(plot_width=400, plot_height=400)
plot.line(‘x’, ‘y’, source=source, line_width=3, line_alpha=0.6)

callback = CustomJS(args=dict(source=source), code=“”"
var data = source.get(‘data’);
var f = cb_obj.get(‘value’)
x = data[‘x’]
y = data[‘y’]
for (i = 0; i < x.length; i++) {
y[i] = Math.pow(x[i], f)
}
source.trigger(‘change’);
“”")

slider = Slider(start=0.1, end=4, value=1, step=.1, title=“power”, callback=callback)

layout = column(slider, plot)

show(layout)

Hi,

I tried this proposed solution (the code below). It does display the slider and the plot. However, there seems to be no link between the slider and the plot in that the doesn’t update when I move the slider. Your advice is much appreciated.

Best,

Kata

Hi,

BokehJS has been under heavy and active development for some time. It's finally quieting down, but still the best place to turn to for up to date examples is the docs:

  https://bokeh.pydata.org/en/latest/docs/user_guide/interaction/callbacks.html

Thanks,

Bryan
