I'm working with large data (~25million points) in Python in Jupyter Notebook and want to have an interactive graph that also doesn't take forever to load. Using Bokeh gives me the interactivity and Holoviews and Datashader allows the data to be graphed relatively quickly.
Python: 3.7.6
Bokeh: 1.4.0
Holoviews: 1.14.3
Numpy: 1.19.5
Pandas: 1.0.1
Numba: 0.48.0
I have no problem running this example code:
import numpy as np, pandas as pd, holoviews as hv
from holoviews.operation.datashader import datashade
hv.extension('bokeh','matplotlib')
n = 100000
dates = pd.date_range(start='1990-01-01', freq='1T', periods=n)
point = hv.Points((dates,
np.random.normal(size=(n,))))
datashade(point, cmap=['red']).opts(width=800)
Which gives a nice graph: 
But when I switch the Holoviews options from "Points" to "Curve" (which was the original code) like so:
import numpy as np, pandas as pd, holoviews as hv
from holoviews.operation.datashader import datashade
hv.extension('bokeh','matplotlib')
n = 100000
dates = pd.date_range(start='1990-01-01', freq='1T', periods=n)
curve = hv.Curve((dates,
np.random.normal(size=(n,))))
datashade(curve, cmap=['red']).opts(width=800)
I am given this long error:

If I remove the "datashade" line and just graph the Holoviews curve graph, then it works fine. But if it was a 25 million point graph, it would take forever, hence why I need Datashader:
import numpy as np, pandas as pd, holoviews as hv
from holoviews.operation.datashader import datashade
hv.extension('bokeh','matplotlib')
n = 100000
dates = pd.date_range(start='1990-01-01', freq='1T', periods=n)
curve = hv.Curve((dates,
np.random.normal(size=(n,)))).opts(width = 1000)
curve
Output graph:
Any ideas as to what could be causing this error? I can provide any additional information if needed.
