Apply the font effects to the data labels

The style_font_effect() method is used to apply the font effects to the Title and Subtitle.

Before formatting the chart is seen in Fig. 832.

Apply to Title

from ooo.dyn.awt.font_underline import FontUnderlineEnum
from ooodev.format.inner.direct.write.char.font.font_effects import FontLine

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

title.style_font_effect(
    color=StandardColor.RED,
    underline=FontLine(line=FontUnderlineEnum.SINGLE, color=StandardColor.BLUE),
    shadowed=True,
)

Running the above code will produce the following output in Fig. 636 and Fig. 637.

Apply to Subtitle

from ooo.dyn.awt.font_underline import FontUnderlineEnum
from ooodev.format.inner.direct.write.char.font.font_effects import FontLine

# ... other code
sub_title = chart_doc.first_diagram.get_title()
if sub_title is None:
    raise ValueError("Title not found")

sub_title.style_font_effect(
    color=StandardColor.RED,
    underline=FontLine(line=FontUnderlineEnum.SINGLE, color=StandardColor.BLUE),
    shadowed=True,
)

Running the above code will produce the following output in Fig. 638.
