Hello, I would like change the color_levels value with panel of already plotted figure, I am trying to do it in that way:
import param
import panel as pn
import numpy as np
import holoviews as hv
from holoviews.streams import Pipe
class Layout(param.Parameterized):
level = param.Number(0.3, bounds=(0.0, 1))
def __init__(self, **params):
super(Layout, self).__init__(**params)
self._waterlvl = [0,self.level,1]
@param.depends("level", watch=True)
def _change_levels(self,):
self._waterlvl = [0,self.level,1]
layout = Layout()
pipe = Pipe(data=[])
pipe.send(np.random.rand(10,10))
Image = hv.DynamicMap(hv.Image, streams=[pipe]).apply.opts(color_levels=layout._waterlvl)
pdmap = pn.panel(Image)
playout = pn.panel(layout)
pn.Row(playout, pdmap)
I guess it just doesn’t update when parameter changes. I also tried to get the object through render and call update(0) method, but I faild with that as well. Could you help me, please?
