在 Python 中创建或更新 PowerPoint 演示文稿图表

本页内容简介

使用 Aspose.Slides for Python via Java 在 PowerPoint 演示文稿中创建和自定义图表。通过实用的 Python 代码示例添加、格式化和编辑图表。

概述

本文提供了使用 Aspose.Slides for Python via Java 创建和自定义图表的完整指南。您将学习如何以编程方式向幻灯片添加图表、填充数据，并应用各种格式选项以满足特定的设计需求。全文通过详细的代码示例展示每一步骤，从初始化演示文稿和图表对象到配置系列、坐标轴和图例。按照本指南操作，您将掌握在 Python 应用程序中集成动态图表生成的技巧，从而简化数据驱动演示文稿的创建过程。

创建图表

图表帮助人们快速可视化数据，并获得从表格或电子表格中不易直接看出的洞察。

为什么要创建图表？

使用图表，您可以：

在一张幻灯片上聚合、压缩或汇总大量数据；
显示数据中的模式和趋势；
推断数据随时间或特定计量单位的方向和动量；
发现异常、偏差、错误和无意义的数据；
传达或展示复杂数据。

在 PowerPoint 中，您可以通过 Insert 功能创建图表，该功能提供多种图表模板。使用 Aspose.Slides，您既可以创建基于常见图表类型的普通图表，也可以创建自定义图表。

Note

使用 ChartType 枚举（位于 asposeslides.api 包中）。该枚举的值对应不同的图表类型。

创建聚簇柱形图

此示例使用 addChart 创建一个聚簇柱形图，用于比较三个类别中的两个系列。两个系列分别使用红色和绿色填充，单独的标签展示类别名称、系列名称和数值。工作表索引 0 指嵌入式图表工作簿的第一张工作表。

结果：

聚簇柱形图

创建散点图

散点图（亦称散点图或 x‑y 图）常用于检查模式或展示两个变量之间的相关性。

在以下情况使用散点图：

您拥有配对的数值数据；
您有两个相互关联的变量；
您希望确定两个变量是否相关；
您有一个自变量对应多个因变量的取值。

此示例绘制两组 x‑y 值。第一系列使用直线和星形标记，第二系列使用平滑曲线和圆形标记；两者的标记大小均为 10，通过 setSize 设置。标记形状通过 setSymbol 方法控制。

import jpype

from asposeslides.api import ChartType, MarkerStyleType, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    chart = slide.getShapes().addChart(ChartType.ScatterWithSmoothLines, 20, 20, 500, 300)

    chart.getChartData().getSeries().add(series_name_cell, chart.getType())

    series = chart.getChartData().getSeries().get_Item(0)

    x_value_cell = workbook.getCell(worksheet_index, 2, 1, 1)
    y_value_cell = workbook.getCell(worksheet_index, 2, 2, 3)
    series.getDataPoints().addDataPointForScatterSeries(x_value_cell, y_value_cell)

    x_value_cell = workbook.getCell(worksheet_index, 3, 1, 2)
    y_value_cell = workbook.getCell(worksheet_index, 3, 2, 10)
    series.getDataPoints().addDataPointForScatterSeries(x_value_cell, y_value_cell)

    series.setType(ChartType.ScatterWithStraightLinesAndMarkers)

    series.getMarker().setSize(10)
    series.getMarker().setSymbol(MarkerStyleType.Star)

    series = chart.getChartData().getSeries().get_Item(1)

    x_value_cell = workbook.getCell(worksheet_index, 2, 3, 5)
    y_value_cell = workbook.getCell(worksheet_index, 2, 4, 2)
    series.getDataPoints().addDataPointForScatterSeries(x_value_cell, y_value_cell)

    x_value_cell = workbook.getCell(worksheet_index, 3, 3, 3)
    y_value_cell = workbook.getCell(worksheet_index, 3, 4, 1)
    series.getDataPoints().addDataPointForScatterSeries(x_value_cell, y_value_cell)

    x_value_cell = workbook.getCell(worksheet_index, 4, 3, 2)
    y_value_cell = workbook.getCell(worksheet_index, 4, 4, 2)
    series.getDataPoints().addDataPointForScatterSeries(x_value_cell, y_value_cell)

    x_value_cell = workbook.getCell(worksheet_index, 5, 3, 5)
    y_value_cell = workbook.getCell(worksheet_index, 5, 4, 1)
    series.getDataPoints().addDataPointForScatterSeries(x_value_cell, y_value_cell)

    series.getMarker().setSymbol(MarkerStyleType.Circle)

    presentation.save("AsposeChart.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

结果：

散点图

创建饼图

饼图最适合展示数据的部分与整体的关系，尤其是当数据包含带数值的分类标签时。不过，如果数据包含大量部分或标签，建议考虑使用柱形图。

此示例创建一个包含三个季度值的饼图。每个切片都有自定义填充和边框，标签显示不同组合的数值、百分比和系列信息。通过 setFirstSliceAngle 方法将第一切片起始角度设为 180 度。

创建折线图

折线图（亦称折线图）最适用于展示随时间变化的数值。使用折线图，您可以一次比较大量数据、跟踪随时间的变化趋势、突出数据系列中的异常等。

此示例使用 addChart 创建一个默认系列和类别的折线图，并将演示文稿保存为 PPTX。

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import ChartType, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    line_chart = slide.getShapes().addChart(ChartType.Line, 20, 20, 500, 300)

    presentation.save("line_chart.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

默认情况下，折线图的点由直线连续相连。如果希望点之间使用虚线连接，调用 setDashStyle，并使用来自 LineDashStyle 的值：

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import ChartType, LineDashStyle, Presentation

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    line_chart = slide.getShapes().addChart(ChartType.Line, 20, 20, 500, 300)

    for series in line_chart.getChartData().getSeries():
        series.getFormat().getLine().setDashStyle(LineDashStyle.Dash)
finally:
    presentation.dispose()

结果：

折线图

创建树形图

树形图在处理销售数据时最为适用，可显示数据类别的相对大小，并快速突出每个类别中贡献大的项目。

此示例创建一个包含八个叶子、分为四个干和两个分支的树形图。通过 setGroupingItem 方法在分组级别 1 分配干，在级别 2 分配分支。值决定矩形的相对大小，类别标签和重叠的父标签标识层级结构。

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpipe.startJVM()

from asposeslides.api import ChartType, ParentLabelLayoutType, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    chart = slide.getShapes().addChart(ChartType.Treemap, 20, 20, 500, 300)

    chart.getChartData().getCategories().clear()
    chart.getChartData().getSeries().clear()

    workbook = chart.getChartData().getChartDataWorkbook()
    workbook.clear(0)

    # 分支 1
    category_cell = workbook.getCell(0, "C1", "Leaf1")
    leaf = chart.getChartData().getCategories().add(category_cell)
    leaf.getGroupingLevels().setGroupingItem(1, "Stem1")
    leaf.getGroupingLevels().setGroupingItem(2, "Branch1")

    category_cell = workbook.getCell(0, "C2", "Leaf2")
    chart.getChartData().getCategories().add(category_cell)

    category_cell = workbook.getCell(0, "C3", "Leaf3")
    leaf = chart.getChartData().getCategories().add(category_cell)
    leaf.getGroupingLevels().setGroupingItem(1, "Stem2")

    category_cell = workbook.getCell(0, "C4", "Leaf4")
    chart.getChartData().getCategories().add(category_cell)

    # 分支 2
    category_cell = workbook.getCell(0, "C5", "Leaf5")
    leaf = chart.getChartData().getCategories().add(category_cell)
    leaf.getGroupingLevels().setGroupingItem(1, "Stem3")
    leaf.getGroupingLevels().setGroupingItem(2, "Branch2")

    category_cell = workbook.getCell(0, "C6", "Leaf6")
    chart.getChartData().getCategories().add(category_cell)

    category_cell = workbook.getCell(0, "C7", "Leaf7")
    leaf = chart.getChartData().getCategories().add(category_cell)
    leaf.getGroupingLevels().setGroupingItem(1, "Stem4")

    category_cell = workbook.getCell(0, "C8", "Leaf8")
    chart.getChartData().getCategories().add(category_cell)

    series = chart.getChartData().getSeries().add(ChartType.Treemap)
    series.getLabels().getDefaultDataLabelFormat().setShowCategoryName(True)
    value_cell = workbook.getCell(0, "D1", 4)
    series.getDataPoints().addDataPointForTreemapSeries(value_cell)
    value_cell = workbook.getCell(0, "D2", 5)
    series.getDataPoints().addDataPointForTreemapSeries(value_cell)
    value_cell = workbook.getCell(0, "D3", 3)
    series.getDataPoints().addDataPointForTreemapSeries(value_cell)
    value_cell = workbook.getCell(0, "D4", 6)
    series.getDataPoints().addDataPointForTreemapSeries(value_cell)
    value_cell = workbook.getCell(0, "D5", 9)
    series.getDataPoints().addDataPointForTreemapSeries(value_cell)
    value_cell = workbook.getCell(0, "D6", 9)
    series.getDataPoints().addDataPointForTreemapSeries(value_cell)
    value_cell = workbook.getCell(0, "D7", 4)
    series.getDataPoints().addDataPointForTreemapSeries(value_cell)
    value_cell = workbook.getCell(0, "D8", 3)
    series.getDataPoints().addDataPointForTreemapSeries(value_cell)

    series.setParentLabelLayout(ParentLabelLayoutType.Overlapping)

    presentation.save("Treemap.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

结果：

树形图

创建瀑布图

瀑布图显示正向和负向变化如何共同构成最终值。例如，利润分解可以从收入开始，减去成本，再加上其他收入。变动列在前后累计值之间浮动，而总计列则从零延伸至累计值。

以下示例使用千美元为单位的金额：

类别	工作簿值	列类型
收入	1000	增加
销售成本	-400	减少
毛利润	600	中间总计
营业费用	-200	减少
其他收入	50	增加
净利润	450	最终总计

若要将某点标记为中间或最终总计，请调用其 setSetAsTotal 方法并传入 True。在该点的工作簿单元格中填写实际累计金额：毛利润为 600（1000 - 400），净利润为 450（600 - 200 + 50）。该方法仅标记列为总计，不会计算或填充值。请勿使用零作为占位符，也不要为总计点提供其他变动值。总计列显示累计值，但不会再次将其加入运行值。

下面的完整 Python 示例使用 ChartType 的 Waterfall 成员创建图表，清除默认数据并填充嵌入式工作簿。工作表索引 0 选择第一张工作表；A 列存放类别名称，B 列存放数值。每个数值单元格通过 addDataPointForWaterfallSeries 添加。零基点索引 2 和 5 标识中间和最终总计。调用 setShowValue 并传入 True 可在列上显示数值。此过程不需要输入演示文稿或工作簿。

import jpage
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import ChartType, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    chart = slide.getShapes().addChart(ChartType.Waterfall, 20, 20, 680, 200)

    chart.setTitle(True)
    chart.getChartTitle().addTextFrameForOverriding("Profit breakdown (USD thousands)")
    chart.getChartTitle().setOverlay(False)
    chart.setLegend(False)

    chart.getChartData().getSeries().clear()
    chart.getChartData().getCategories().clear()

    workbook = chart.getChartData().getChartDataWorkbook()
    worksheet_index = 0

    workbook.clear(worksheet_index)

    series_name_cell = workbook.getCell(worksheet_index, 0, 1, "Profit")
    series = chart.getChartData().getSeries().add(series_name_cell, ChartType.Waterfall)
    categories = ["Revenue", "Cost of sales", "Gross profit", "Operating expenses", "Other income", "Net profit"]
    values = [1000, -400, 600, -200, 50, 450]

    for i in range(len(categories)):
        category_cell = workbook.getCell(worksheet_index, i + 1, 0, categories[i])
        chart.getChartData().getCategories().add(category_cell)
        value_cell = workbook.getCell(worksheet_index, i + 1, 1, values[i])
        series.getDataPoints().addDataPointForWaterfallSeries(value_cell)

    # 第三和第六个点表示总计，而不是额外的变动。
    series.getDataPoints().get_Item(2).setSetAsTotal(True)
    series.getDataPoints().get_Item(5).setSetAsTotal(True)
    series.setShowConnectorLines(True)
    series.getLabels().getDefaultDataLabelFormat().setShowValue(True)

    presentation.save("WaterfallChart.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

在系列级别调用 setShowConnectorLines 并传入 True，即可显示连接相邻列的线，使运行值更易追踪。若要隐藏这些线，只需在示例中将方法调用替换为 series.setShowConnectorLines(False)，并在保存前执行。此更改仅影响线的可见性，不会改变数据或总计。

保存后的演示文稿显示毛利润为 600，净利润为 450，两者均从零开始绘制：

瀑布图，显示收入、成本、毛利润 600 和净利润 450，带数值标签和连接线

创建股票图

股票图用于展示金融数据，如开盘价、最高价、最低价和收盘价，帮助分析市场趋势和波动性。它们提供对股票表现的关键洞察，帮助投资者和分析师做出明智决策。

此示例创建一个包含四个系列（顺序为开‑高‑低‑收）的股票图，覆盖三个类别。通过 setUpDownBars 方法启用上下柱，使用 getHiLowLinesFormat 控制显示价格区间的高低线，同时隐藏单独系列线和次水平网格线。

更新图表

Aspose.Slides for Python via Java 使您能够通过修改图表数据、格式和样式来更新 PowerPoint 图表。这一功能简化了保持演示文稿与动态内容同步的过程，确保图表准确反映当前数据和视觉标准。

此示例更新现有演示文稿第一张幻灯片中名为 “My chart” 的图表。它要求两个列系列，每个系列有三个数据点，类别标签位于 A 列，系列名称位于工作表首行。示例使用 getCell 更改工作簿单元格，更新系列值，添加第三个系列，并通过 setType 将图表类型改为聚簇圆柱体。

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Chart, ChartType, Presentation, SaveFormat

chart_name = "My chart"

presentation = Presentation("ExistingChart.pptx")
try:
    slide = presentation.getSlides().get_Item(0)

    for shape in slide.getShapes():
        if isinstance(shape, Chart) and chart_name == shape.getName():
            chart = shape
            worksheet_index = 0

            workbook = chart.getChartData().getChartDataWorkbook()

            workbook.getCell(worksheet_index, 1, 0, "Modified Category 1")
            workbook.getCell(worksheet_index, 2, 0, "Modified Category 2")

            series = chart.getChartData().getSeries().get_Item(0)

            workbook.getCell(worksheet_index, 0, 1, "New_Series 1")
            series.getDataPoints().get_Item(0).getValue().setData(90)
            series.getDataPoints().get_Item(1).getValue().setData(123)
            series.getDataPoints().get_Item(2).getValue().setData(44)

            series = chart.getChartData().getSeries().get_Item(1)

            workbook.getCell(worksheet_index, 0, 2, "New_Series 2")
            series.getDataPoints().get_Item(0).getValue().setData(23)
            series.getDataPoints().get_Item(1).getValue().setData(67)
            series.getDataPoints().get_Item(2).getValue().setData(99)

            series_name_cell = workbook.getCell(worksheet_index, 0, 3, "Series 3")
            series = chart.getChartData().getSeries().add(series_name_cell, chart.getType())

            value_cell = workbook.getCell(worksheet_index, 1, 3, 20)
            series.getDataPoints().addDataPointForBarSeries(value_cell)
            value_cell = workbook.getCell(worksheet_index, 2, 3, 50)
            series.getDataPoints().addDataPointForBarSeries(value_cell)
            value_cell = workbook.getCell(worksheet_index, 3, 3, 30)
            series.getDataPoints().addDataPointForBarSeries(value_cell)

            chart.setType(ChartType.ClusteredCylinder)

    presentation.save("AsposeChartModified.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

为图表设置数据范围

要检查现有图表已使用的范围，请参阅 Retrieve a Chart’s Data Range。

Aspose.Slides for Python via Java 提供将工作表的特定数据范围定义为图表数据源的灵活性。这意味着您可以直接映射工作表的某一部分到图表，从而控制哪些单元格贡献于图表的系列和类别。借此，您可以轻松更新和同步图表，使其始终反映工作表中的最新数据，确保演示文稿信息准确、及时。

此示例使用 setRange 将现有演示文稿第一张幻灯片中名为 “My chart” 的图表的数据源设置为 Sheet1!A1:B4。图表工作簿必须包含该工作表，并且该范围需已填充数据，首行作为系列标题，A 列为类别标签，B 列包含三个数值。

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import Chart, Presentation, SaveFormat

chart_name = "My chart"

presentation = Presentation("ExistingChart.pptx")
try:
    slide = presentation.getSlides().get_Item(0)

    for shape in slide.getShapes():
        if isinstance(shape, Chart) and chart_name == shape.getName():
            chart = shape
            chart.getChartData().setRange("Sheet1!A1:B4")

    presentation.save("SetDataRange.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

在图表中使用默认标记

使用默认标记时，每个图表系列会自动获得不同的默认标记符号。

此示例使用 addChart 创建一个包含两条折线系列和图例的图表。通过 getMarker 访问的标记设置保留了自动分配的标记符号。第一系列包含一个负值和一个缺失值（使用 None 表示），第二系列在每个类别都有数值。

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import ChartType, Presentation, SaveFormat

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    chart = slide.getShapes().addChart(ChartType.LineWithMarkers, 10, 10, 400, 400)

    chart.getChartData().getSeries().clear()
    chart.getChartData().getCategories().clear()

    workbook = chart.getChartData().getChartDataWorkbook()

    series_name_cell = workbook.getCell(0, 0, 1, "Series 1")
    series = chart.getChartData().getSeries().add(series_name_cell, chart.getType())

    category_cell = workbook.getCell(0, 1, 0, "C1")
    chart.getChartData().getCategories().add(category_cell)
    value_cell = workbook.getCell(0, 1, 1, 24)
    series.getDataPoints().addDataPointForLineSeries(value_cell)

    category_cell = workbook.getCell(0, 2, 0, "C2")
    chart.getChartData().getCategories().add(category_cell)
    value_cell = workbook.getCell(0, 2, 1, 23)
    series.getDataPoints().addDataPointForLineSeries(value_cell)

    category_cell = workbook.getCell(0, 3, 0, "C3")
    chart.getChartData().getCategories().add(category_cell)
    value_cell = workbook.getCell(0, 3, 1, -10)
    series.getDataPoints().addDataPointForLineSeries(value_cell)

    category_cell = workbook.getCell(0, 4, 0, "C4")
    chart.getChartData().getCategories().add(category_cell)
    value_cell = workbook.getCell(0, 4, 1, None)
    series.getDataPoints().addDataPointForLineSeries(value_cell)

    series_name_cell = workbook.getCell(0, 0, 2, "Series 2")
    second_series = chart.getChartData().getSeries().add(series_name_cell, chart.getType())

    value_cell = workbook.getCell(0, 1, 2, 30)
    second_series.getDataPoints().addDataPointForLineSeries(value_cell)
    value_cell = workbook.getCell(0, 2, 2, 10)
    second_series.getDataPoints().addDataPointForLineSeries(value_cell)
    value_cell = workbook.getCell(0, 3, 2, 60)
    second_series.getDataPoints().addDataPointForLineSeries(value_cell)
    value_cell = workbook.getCell(0, 4, 2, 40)
    second_series.getDataPoints().addDataPointForLineSeries(value_cell)

    chart.setLegend(True)
    chart.getLegend().setOverlay(False)

    presentation.save("DefaultMarkersInChart.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()
