Chart
aspose-cells-foss suportă încorporarea diagramelor în foile de calcul. Diagramele sunt gestionate prin ws.charts, un ChartCollection atașat fiecărui Worksheet. Datele seriei sunt adăugate prin chart.n_series, un NSeries colecție.

add
ws.charts.add(
chart_type: ChartType,
upper_left_row: int,
upper_left_column: int,
lower_right_row: int,
lower_right_column: int
) -> ChartAdaugă o diagramă de tipul specificat. Toate argumentele de poziție sunt indici de rând/coloană începând de la 0.
add_bar
ws.charts.add_bar(upper_left_row, upper_left_column, lower_right_row, lower_right_column) -> ChartScurtătură pentru add(ChartType.BAR, ...).
add_line
ws.charts.add_line(upper_left_row, upper_left_column, lower_right_row, lower_right_column) -> ChartScurtătură pentru add(ChartType.LINE, ...).
add_pie
ws.charts.add_pie(upper_left_row, upper_left_column, lower_right_row, lower_right_column) -> ChartScurtătură pentru add(ChartType.PIE, ...).
add_area
ws.charts.add_area(upper_left_row, upper_left_column, lower_right_row, lower_right_column) -> ChartScurtătură pentru add(ChartType.AREA, ...).
Proprietăți și iterare
NSeries
NSeries este accesat prin chart.n_series. Gestionează seriile de date care aparțin unui grafic.

add
chart.n_series.add(
area: str,
is_vertical: bool = False,
category_data: str | None = None,
name: str | None = None,
chart_type: ChartType | None = None
) -> ChartSeriesAdaugă o serie de date. area este un șir de interval, cum ar fi "Sheet1!B1:B5". Setează is_vertical=True când datele sunt aranjate în coloane. chart_type suprascrie tipul de grafic părinte pentru această serie (utilizat în grafice combinate).
Proprietăți și iterare
ChartSeries
ChartSeries reprezintă o singură serie de date într-un grafic. Obținută prin chart.n_series[index].

add_error_bars
series.add_error_bars(
direction='y',
bar_type='both',
val_type='fixedVal',
val=1.0,
no_end_cap=False
) -> ChartErrorBarsAdaugă bare de eroare la această serie și returnează ChartErrorBars obiectul.
ChartAxis
ChartAxis este accesat prin chart.axes[index].

ChartView3D
ChartView3D este accesat prin chart.view_3d. Se aplică numai când chart.is_3d este True.
