This looks like the api bug, can you narrow this down to fewer steps to reproduce?

I'm not yet sure how to narrow down the setup steps, but I was able to reproduce this in code (not just the chart builder)

# This works
simple_line_plot = Figure().plot_xy(
    series_name="BTC Price", 
    t=crypto_btc_2021.tail(2_000), # NOTE: how this is limited to 2000 records
    x="Timestamp", 
    y="Price").show()

# This fails    
simple_line_plot = Figure().plot_xy(
    series_name="BTC Price", 
    t=crypto_btc_2021, # NOTE: this is unbounded
    x="Timestamp", 
    y="Price").show()
