The default fill_method='pad' in Series.pct_change is deprecated and will be removed in a future version. Either fill in any non-leading NA values prior to calling pct_change or specify 'fill_method=None' to not fill NA values.

## Visualize Principal Component 1
pc1, loadings = pca_index.pca(dfn, module="scikitlearn")
pc1.plot();

# Simple version
fig = px.line(pc1)
fig.show()

# Using slider and quick views
pca_index.pc1_line_plot(pc1)

## Visualize normalized and raw series
dfn.plot(subplots=True, figsize=(10, 10));
