It works as expected for interactive plots: but it does not for noninteractive: The code used to generate the plots:

import numpy as np
import pandas as pd
from edvart.plots import scatter_plot_2d

df = pd.DataFrame({'a': np.arange(10) * 200, 'b': np.arange(10)})

scatter_plot_2d(df=df, x='a', y='b', equal_scale_axes=True, interactive=False)

Thanks, fixed by using a different setting to scale the axes.
