See this example:
import pandas as pd
import hvplot.pandas
# Create dataframe of length 1-10 and the ordering is fine
df = pd.DataFrame({col: range(20) for col in range(10)})
# Nice ordering.
chart_1 = df.count().to_frame().T.hvplot.bar(rot=90, width=1400, height=500)
chart_1
# Create dataframe of lenght > 10 and the ordering is now reversed
df = pd.DataFrame({col: range(20) for col in range(11)})
# Reverse ordering.
chart_2 = df.count().to_frame().T.hvplot.bar(rot=90, width=1400, height=500)
chart_2
