Chart
aspose-cells-foss suporta a incorporação de gráficos em planilhas. Os gráficos são gerenciados através de ws.charts, uma ChartCollection anexado a cada Worksheet. Os dados da série são adicionados através de chart.n_series, um NSeries coleção.
Example: aspose.cells_foss
from aspose.cells_foss import ChartTypeChartType

Example
Chart os objetos não são construídos diretamente. Use ws.charts.add(...) ou os métodos de conveniência tipados (add_bar(), add_line(), add_pie(), add_area()).
Example
| Signature | Description |
|---|---|
__init__(chart_type, upper_left_row, upper_left_column, lower_right_row, lower_right_column) | |
add_series(values, category_data, name, chart_type, x_values) | Convenience method to add a series. |
add_axis(axis_type, axis_id) | Adds an axis to the chart and returns it. |
copy() | Creates and returns a duplicate of the chart |
ChartCollection
ChartCollection é acessado como ws.charts. Contém todos os gráficos incorporados em uma planilha.
Example
add
ws.charts.add(
chart_type: ChartType,
upper_left_row: int,
upper_left_column: int,
lower_right_row: int,
lower_right_column: int
) -> ChartAdiciona um gráfico do tipo especificado. Todos os argumentos de posição são índices de linha/coluna baseados em 0.
add_bar
ws.charts.add_bar(upper_left_row, upper_left_column, lower_right_row, lower_right_column) -> ChartAtalho para add(ChartType.BAR, ...).
add_line
ws.charts.add_line(upper_left_row, upper_left_column, lower_right_row, lower_right_column) -> ChartAtalho para add(ChartType.LINE, ...).
add_pie
ws.charts.add_pie(upper_left_row, upper_left_column, lower_right_row, lower_right_column) -> ChartAtalho para add(ChartType.PIE, ...).
add_area
ws.charts.add_area(upper_left_row, upper_left_column, lower_right_row, lower_right_column) -> ChartAtalho para add(ChartType.AREA, ...).
Propriedades e iteração
NSeries
NSeries é acessado via chart.n_series. Ele gerencia as séries de dados pertencentes a um gráfico.
Example
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
) -> ChartSeriesAdiciona uma série de dados. area é uma string de intervalo como "Sheet1!B1:B5". Defina is_vertical=True quando os dados são organizados em colunas. chart_type substitui o tipo de gráfico pai para esta série (usado em gráficos combinados).
Propriedades e iteração
ChartSeries
ChartSeries representa uma única série de dados dentro de um gráfico. Obtido via chart.n_series[index].
Example
Example
add_error_bars
series.add_error_bars(
direction='y',
bar_type='both',
val_type='fixedVal',
val=1.0,
no_end_cap=False
) -> ChartErrorBarsAdiciona barras de erro a esta série e retorna o ChartErrorBars objeto.
ChartAxis
ChartAxis é acessado via chart.axes[index].
Example
ChartView3D
ChartView3D é acessado via chart.view_3d. Aplica‑se apenas quando chart.is_3d é True.
Example
ChartErrorBars
ChartErrorBars é acessado via series.error_bars.Criar com series.add_error_bars(...).
Example
Example
O exemplo a seguir grava dados de receita mensal, cria um gráfico de barras agrupadas com um título e duas séries de dados, e salva a pasta de trabalho.
