subcoordinates_y breaks DynamicMap

[ahuang11]

from functools import partial
import holoviews as hv
from holoviews.streams import RangeX
hv.extension("bokeh")


def update(x0, x_range):
    if not x_range:
        x_range = [0, 1]
    print(x_range)
    xdata = [x0, 1, 2, x_range[-1]]
    return hv.Curve(((xdata, (0, 1, 2, 3))), label=str(x0)).opts(subcoordinate_y=True)


range_x = RangeX()
overlay = hv.Overlay([])
overlay *= hv.DynamicMap(partial(update, 0), streams=[range_x])
overlay *= hv.DynamicMap(partial(update, 1), streams=[range_x])
overlay

Removing subcoordinate_y makes the dynamicmap update again.

What version of holoviews are you using? Can you try running on main (if not already)

[ahuang11]

Originally 1.18.1; now main, but same behavior.

Here's another variation that also doesn't work :):

from functools import partial
import panel as pn
import holoviews as hv
from holoviews.streams import RangeX
hv.extension("bokeh")


def update(x_range):
    if not x_range:
        x_range = [0, 1]
    print(x_range)
    overlay = hv.Overlay([])
    for x0 in [0, 1]:
        xdata = [x0, 1, 2, x_range[-1]]
        overlay *= hv.Curve(((xdata, (0, 1, 2, 3))), label=str(x0)).opts(subcoordinate_y=True)
    return overlay


range_x = RangeX()
overlay = hv.DynamicMap(update, streams=[range_x])
overlay

[hoxbro]

Are you sure it is the same behavior because the zoom tool should behave differently on the main? Because of #6051

[ahuang11]

Okay, maybe it's just RangeX that doesn't work?

from functools import partial
import panel as pn
import holoviews as hv
from holoviews.streams import Tap
hv.extension("bokeh")


def update(x, y):
    # if not x_range:
    #     x_range = [0, 1]
    # print(x_range)
    print(x, y)
    overlay = hv.Overlay([])
    for x0 in [0, 1]:
        xdata = [x0, 1, 2, y]
        overlay *= hv.Curve(((xdata, (0, 1, 2, 3))), label=str(x0)).opts(subcoordinate_y=True)
    return overlay


range_x = Tap()
overlay = hv.DynamicMap(update, streams=[range_x])
overlay

:) Wow @hoxbro you're quite magical.

I forgot to pull the latest main...
