DynamicMap is not updated when embedded in dynamic Tabs #2865
Description
It seems like holoviews DynamicMap is not updated when embedded in panel Tabs when dynamic is set to True.
See example below with two videos (first with dynamic=False, second with dynamic=True). Only with dynamic=False the figure is updated as expected.
I am not sure if it is a holoviews or a panel problem.
ALL software version info
panel=0.12.4
holoviews=1.14.6
bokeh=2.4.0
Complete, minimal, self-contained example code that reproduces the issue (with dynamic=True)
import numpy as np
import holoviews as hv
from holoviews import opts
from holoviews.streams import Stream, param
import panel as pn
hv.extension('bokeh')
pn.extension()
lin = np.linspace(-np.pi,np.pi,300)
def lissajous(t, a=3, b=5, delta=np.pi/2.):
return (np.sin(a * t + delta), np.sin(b * t))
def lissajous_crosshair(t, a=3, b=5, delta=np.pi/2):
(x,y) = lissajous(t,a,b,delta)
return hv.VLine(x) * hv.HLine(y)
path = hv.Path(lissajous(lin))
Time = Stream.define('Time', t=param.Number(default=0.0, doc='A time parameter'))
time = Time(t=np.pi/4)
dmap = hv.DynamicMap(lissajous_crosshair, streams=[time])
def button_click(event):
dmap.event(t=button.clicks)
button = pn.widgets.Button(name='change dmap')
button.on_click(button_click)
app = pn.Tabs(('Plot', path * dmap),
('Button', button),
dynamic=True)
app.show()
