Plots not updating with Select widget

Hi,

My plot cannot update with Select widget. Any suggestions?

Thanks

Hi,

It is impossible to say anything about a question this vague. It is always necessary to share more details (code) if you want people to try and help.

Thanks,

Bryan

Hi Bryan,

Sorry about that. The code would be something like this:

from bokeh.io import curdoc, output_file

from bokeh.layouts import column

from bokeh.models import ColumnDataSource, RadioButtonGroup, Select

from bokeh.plotting import figure

from bokeh.sampledata.iris import flowers

species = [‘setosa’, ‘versicolor’, ‘virginica’]

menu = Select(options=[‘setosa’,‘versicolor’,‘virginica’],value=‘setosa’, title=‘Species’, width = 100)

menu.on_change(‘value’,lambda attr, old, new: update_plot())

def update_plot():

current = flowers[flowers.species == menu.value]

return dict(

		width = current.sepal_width,

		length = current.sepal_length,

	)

flowers_cds = ColumnDataSource(data=dict(width=,length=))

flowers_cds.data = update_plot()

plot = figure()

plot.circle(x=‘width’, y=‘length’, source=flowers_cds)

curdoc().add_root(column(menu, plot))

Thanks!
