print a number in bokeh app

Hi,

Is there any way to show a output number with bokeh app?

For example, I would like to see the calculated results with figures

import numpy as np
from bokeh.plotting import output_file, figure, show

x = np.linspace(0, 4*np.pi, 100)
y = np.sin(x)

output_file(“legend_labels.html”)

p = figure()

p.circle(x, y, legend=“sin(x)”)

t=30

print(t)
show(p)
I am using Bokeh 0.12.6 with python 3.6

Thank you in advance!!!

with best regards,

Moshiour

Hi,

I wasn’t quite sure what you were after here, but if it’s displaying the y values of the plotted points, the changes to your example shown below should help. Or, if you’re after a text box to put below your plot, you’ll need a widget: see here - the Div widget should do the job.

Hope that helps,
Marcus.

import numpy as np
from bokeh.plotting import output_file, figure, show
from bokeh.models import LabelSet
from bokeh.models.sources import ColumnDataSource

x = np.linspace(0, 4*np.pi, 100)
y = np.sin(x)
t = [’{:.2f}’.format(ye) for ye in y]
src = ColumnDataSource(data=dict(x=x, y=y, t=t))

l = LabelSet(x=‘x’, y=‘y’, text=‘t’, source=src)

p = figure()

p.circle(‘x’, ‘y’, source=src, legend=“sin(x)”)
p.add_layout(l)

output_file(“legend_labels.html”)

show(p)
