Chart2 Direct Title/Subtitle Font Only

Overview

The style_font() method is used to set the font of the Title and Subtitle of a Chart, similar options as Fig. 821 Font Dialog, but without the dialog.

Setup

General setup for this example.

from __future__ import annotations
from pathlib import Path
import uno
from ooo.dyn.awt.gradient_style import GradientStyle
from ooodev.calc import CalcDoc, ZoomKind
from ooodev.loader.lo import Lo
from ooodev.utils.color import StandardColor
from ooodev.utils.data_type.color_range import ColorRange

def main() -> int:
    with Lo.Loader(connector=Lo.ConnectPipe()):
        fnm = Path.cwd() / "tmp" / "piechart.ods"
        doc = CalcDoc.open_doc(fnm=fnm, visible=True)
        Lo.delay(500)
        doc.zoom(ZoomKind.ZOOM_100_PERCENT)

        sheet = doc.sheets[0]
        sheet["A1"].goto()
        chart_table = sheet.charts[0]
        chart_doc = chart_table.chart_doc
        _ = chart_doc.style_border_line(
            color=StandardColor.PURPLE_DARK1,
            width=0.7,
        )
        _ = chart_doc.style_area_gradient(
            step_count=64,
            style=GradientStyle.SQUARE,
            angle=45,
            grad_color=ColorRange(
                StandardColor.BLUE_DARK1,
                StandardColor.PURPLE_LIGHT2,
            ),
        )

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

        title.style_font(
            name="Lucida Calligraphy",
            size=14,
            font_style="italic",
        )
        Lo.delay(1_000)
        doc.close()
    return 0

if __name__ == "__main__":
    SystemExit(main())

Apply the Font

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_font(
    name="Lucida Calligraphy",
    size=14,
    font_style="italic",
)

Running the above code will produce the following output shown in Fig. 639 and Fig. 640.

Chart Data Labels Dialog Font — Fig. 640 Chart Data Labels Dialog Font

Apply to Subtitle

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

sub_title.style_font(
    name="Lucida Calligraphy",
    size=14,
    font_style="italic",
)

Running the above code will produce the following output shown in Fig. 641.
