Properties

Chart 对象不能直接构造。使用 ws.charts.add(...) 或使用类型化的便利方法（add_bar(), add_line(), add_pie(), add_area()).

Properties

SignatureDescription
__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 可通过以下方式访问 ws.charts. 它包含工作表中嵌入的所有图表。.

Properties

add 

ws.charts.add(
    chart_type: ChartType,
    upper_left_row: int,
    upper_left_column: int,
    lower_right_row: int,
    lower_right_column: int
) -> Chart

添加指定类型的图表。所有位置参数均为从 0 开始的行/列索引。.

add_bar 

ws.charts.add_bar(upper_left_row, upper_left_column, lower_right_row, lower_right_column) -> Chart

快捷键用于 add(ChartType.BAR, ...).

add_line 

ws.charts.add_line(upper_left_row, upper_left_column, lower_right_row, lower_right_column) -> Chart

快捷键 add(ChartType.LINE, ...).

add_pie 

ws.charts.add_pie(upper_left_row, upper_left_column, lower_right_row, lower_right_column) -> Chart

快捷键 add(ChartType.PIE, ...).

add_area 

ws.charts.add_area(upper_left_row, upper_left_column, lower_right_row, lower_right_column) -> Chart

快捷键 add(ChartType.AREA, ...).

属性和迭代

NSeries

NSeries 通过…访问 chart.n_series.。它管理属于图表的数据系列。.

Properties

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
) -> ChartSeries

添加一个数据系列。. area 是一个范围字符串，例如 "Sheet1!B1:B5".。设置 is_vertical=True 当数据按列排列时。. chart_type 覆盖此系列的父图表类型（用于组合图表）。.

属性和迭代

ChartSeries

ChartSeries 表示图表中的单个数据系列。通过以下方式获取： chart.n_series[index].

Properties

Properties

add_error_bars 

series.add_error_bars(
    direction='y',
    bar_type='both',
    val_type='fixedVal',
    val=1.0,
    no_end_cap=False
) -> ChartErrorBars

为此系列添加误差线并返回 ChartErrorBars 对象。.

ChartAxis

ChartAxis 通过以下方式访问 chart.axes[index].

Properties

ChartView3D

ChartView3D 通过以下方式访问 chart.view_3d.。仅在以下情况下适用 chart.is_3d 为 True.

Properties

ChartErrorBars

ChartErrorBars 通过 series.error_bars.。使用以下方式创建 series.add_error_bars(...).

Properties

Properties

下面的示例写入月度收入数据，创建带标题和两个数据系列的簇状条形图，并保存工作簿。.

from aspose.cells_foss import Workbook, ChartType

wb = Workbook()
ws = wb.worksheets[0]
ws.name = "Revenue"

# Write headers and data
headers = ["Month", "Product A", "Product B"]
data = [
    ["Jan", 12000, 9500],
    ["Feb", 14500, 11000],
    ["Mar", 13200, 12800],
    ["Apr", 15800, 14100],
]
for col, h in enumerate(headers):
    ws.cells[0][col].put_value(h)
for row, row_data in enumerate(data, start=1):
    for col, val in enumerate(row_data):
        ws.cells[row][col].put_value(val)

# Add a bar chart covering rows 6-20, columns 0-6
chart = ws.charts.add_bar(6, 0, 20, 6)
chart.title = "Monthly Revenue by Product"
chart.bar_direction = "col"   # vertical (column chart)
chart.grouping = "clustered"

# Series: Product A and Product B
chart.n_series.add("Revenue!B2:B5", is_vertical=True, category_data="Revenue!A2:A5", name="Product A")
chart.n_series.add("Revenue!C2:C5", is_vertical=True, category_data="Revenue!A2:A5", name="Product B")

chart.show_legend = True
chart.legend_position = "bottom"

wb.save("revenue_chart.xlsx")
