Problem Description

So no plots show up in version 6.0.0b2.

What steps reproduce the problem?

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

# Generate 1 million random datetimes using pandas
start_time = '2020-01-01 00:00:00'
datetime_range = pd.date_range(start=start_time, periods=1_000_000, freq='min')

# Generate 1 million random floats
random_floats = np.random.random(1_000_000)

# Sort the random floats
sorted_random_floats = np.sort(random_floats)

# Create Polars DataFrame
df = pd.DataFrame({
    'datetime': datetime_range,
    'sorted_random_floats': sorted_random_floats
})

# Plot the first 1000 sorted random float values against their datetime values
plt.figure(figsize=(10, 6))
plt.plot(df['datetime'][:1000], df['sorted_random_floats'][:1000])
plt.xlabel('Datetime')
plt.ylabel('Sorted Random Floats')
plt.title('Sorted Random Float Values Over Time')
plt.xticks(rotation=45)
plt.tight_layout()
plt.show()

What is the expected output?

That i can see plots
