Chart2 Direct Series Data Labels Font Only

Overview

The ooodev.format.chart2.direct.series.data_labels.font.FontOnly class gives you similar options for data labels as Fig. 788 Font Dialog, but without the dialog.

Calls to the Chart2.style_data_series() and Chart2.style_data_point() methods are used to set the data labels font of a Chart.

Setup

General setup for this example.

from __future__ import annotations
from pathlib import Path
import uno
from ooodev.calc import CalcDoc, ZoomKind
from ooodev.loader.lo import Lo
from ooodev.format.inner.preset.preset_gradient import PresetGradientKind
from ooodev.utils.color import StandardColor

def main() -> int:
    with Lo.Loader(connector=Lo.ConnectPipe()):
        fnm = Path.cwd() / "tmp" / "col_chart.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.BLUE_LIGHT3,
            width=0.7,
        )
        _ = chart_doc.style_area_gradient_from_preset(
            preset=PresetGradientKind.TEAL_BLUE,
        )

        ds = chart_doc.get_data_series()[0]
        ds.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 to Data Labels

Before formatting the chart is seen in Fig. 829.

Style Data Series

# ... other code
ds = chart_doc.get_data_series()[0]
ds.style_font(name="Lucida Calligraphy", size=14, font_style="italic")

Running the above code will produce the following output shown in Fig. 607 and Fig. 608.

Style Data Point

# ... other code
ds = chart_doc.get_data_series()[0]
dp = ds[0]
dp.style_font(name="Lucida Calligraphy", size=14, font_style="italic")

Running the above code will produce the following output shown in Fig. 609.
