ValueError: assignment destination is read-only when using hvplot.quadmesh with resampled xarray dataset about geoviews

[Hoxbro]

We can only find out what the problem is with a minimal, reproducible example (MRE).

Sorry for the delay; for some reason I encountered some difficulties in recreating the error with a MRE, but here's what I came up with:

import hvplot.xarray
import numpy as np
import pandas as pd
import xarray as xr

TT = np.random.randn(100, 100, 24)
lon = list(range(0, 100))
lat = list(range(0, 100))
time = pd.date_range("2023-07-05", periods=24, freq="1H")

ds = xr.Dataset(
    data_vars=dict(
        TT=(["lon", "lat", "time"], TT),
    ),
    coords=dict(lon=(["lon"], lon), lat=(["lat"], lat), time=(["time"], time)),
).chunk()

ds = ds.resample(time="3H").max()

ds.isel(time=0).hvplot.quadmesh(
    geo=True,
    project=True,
    rasterize=True,
    dynamic=True,
)

I don't get the error what are your versions of HoloViews and Datashader?

[morf1102]

Holoviews : 1.16.1
Datashader: 0.15.0

Those seem like recent enough versions. Where do you see the error in Jupyter notebook / Jupyter lab / VScode?
