Applying Line Properties

The style_border_line() method is called to set the title and subtitle border line properties.

Before formatting the chart is seen in Fig. 832.

Apply to Title

# ... other code

title = chart_doc.get_title()
if title is None:
    raise ValueError("Title not found")

title.style_border_line(
    color=StandardColor.MAGENTA_DARK1,
    width=0.75,
)

The results are seen in Fig. 631 and Fig. 632.
