图表和SmartArt是现代文档中展示数据和概念的重要工具。Aspose.Words提供了强大的图表创建和编辑功能,支持多种图表类型和SmartArt图形。本教程将介绍如何使用Aspose.Words for .NET创建专业的图表和SmartArt,提升文档的数据可视化效果。

11.1 图表类型与创建方法

支持的图表类型

Aspose.Words支持多种图表类型:

  • 柱状图:Column, Bar, Clustered Column等
  • 折线图:Line, Area, Scatter等
  • 饼图:Pie, Doughnut等
  • 其他:Bubble, Stock等专业图表

基础图表创建

using Aspose.Words;
using Aspose.Words.Drawing;
using Aspose.Words.Drawing.Charts;

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.Font.Size = 16;
builder.Font.Bold = true;
builder.Writeln("销售数据分析报告");
builder.Font.Bold = false;
builder.Writeln();

// 1. 创建柱状图
builder.Writeln("季度销售对比:");
Shape columnChart = builder.InsertChart(ChartType.Column, 400, 300);
Chart chart1 = columnChart.Chart;

// 清除默认数据
chart1.Series.Clear();

// 添加数据系列
ChartSeries series1 = chart1.Series.Add("2023年", 
    new string[] { "Q1", "Q2", "Q3", "Q4" },
    new double[] { 1200000, 1400000, 1600000, 1800000 });
    
ChartSeries series2 = chart1.Series.Add("2024年",
    new string[] { "Q1", "Q2", "Q3", "Q4" },
    new double[] { 1350000, 1550000, 1750000, 2000000 });

// 设置图表标题
chart1.Title.Text = "季度销售额对比(万元)";
chart1.Title.Show = true;

builder.Writeln();
builder.Writeln();

// 2. 创建折线图
builder.Writeln("月度增长趋势:");
Shape lineChart = builder.InsertChart(ChartType.Line, 400, 250);
Chart chart2 = lineChart.Chart;

chart2.Series.Clear();
chart2.Series.Add("销售增长率",
    new string[] { "1月", "2月", "3月", "4月", "5月", "6月" },
    new double[] { 8.5, 12.3, 15.7, 18.2, 22.1, 25.4 });

chart2.Title.Text = "月度销售增长率(%)";
chart2.Title.Show = true;

builder.Writeln();
builder.Writeln();

// 3. 创建饼图
builder.Writeln("产品销售占比:");
Shape pieChart = builder.InsertChart(ChartType.Pie, 350, 350);
Chart chart3 = pieChart.Chart;

chart3.Series.Clear();
chart3.Series.Add("产品占比",
    new string[] { "产品A", "产品B", "产品C", "产品D", "其他" },
    new double[] { 35.5, 28.3, 18.7, 12.2, 5.3 });

chart3.Title.Text = "产品销售占比分析";
chart3.Title.Show = true;

doc.Save("基础图表创建.docx");

11.2 图表数据源配置与格式化

动态数据绑定和样式设置

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.Writeln("动态数据图表示例");
builder.Writeln();

// 创建复杂的柱状图
Shape chartShape = builder.InsertChart(ChartType.Column, 500, 350);
Chart chart = chartShape.Chart;

// 清除默认系列
chart.Series.Clear();

// 模拟从数据库或其他源获取的数据
var salesData = new[]
{
    new { Region = "华北", Q1 = 850, Q2 = 920, Q3 = 1050, Q4 = 1180 },
    new { Region = "华东", Q1 = 1200, Q2 = 1350, Q3 = 1480, Q4 = 1620 },
    new { Region = "华南", Q1 = 680, Q2 = 750, Q3 = 820, Q4 = 950 },
    new { Region = "西部", Q1 = 450, Q2 = 520, Q3 = 580, Q4 = 640 }
};

string[] categories = { "Q1", "Q2", "Q3", "Q4" };
Color[] seriesColors = { Color.Blue, Color.Green, Color.Orange, Color.Red };

// 为每个地区添加数据系列
for (int i = 0; i < salesData.Length; i++)
{
    var data = salesData[i];
    double[] values = { data.Q1, data.Q2, data.Q3, data.Q4 };
    
    ChartSeries series = chart.Series.Add(data.Region, categories, values);
    
    // 设置系列颜色
    if (i < seriesColors.Length)
    {
        for (int j = 0; j < series.DataPoints.Count; j++)
        {
            series.DataPoints[j].Format.Fill.ForeColor = seriesColors[i];
        }
    }
}

// 图表整体格式设置
chart.Title.Text = "各地区季度销售业绩(万元)";
chart.Title.Show = true;

// 设置坐标轴
ChartAxis xAxis = chart.AxisX;
xAxis.Title.Text = "季度";
xAxis.Title.Show = true;

ChartAxis yAxis = chart.AxisY;
yAxis.Title.Text = "销售额(万元)";
yAxis.Title.Show = true;
yAxis.MajorUnit = 200;

// 设置图例
chart.Legend.Show = true;
chart.Legend.Position = LegendPosition.Bottom;

// 设置数据标签
foreach (ChartSeries series in chart.Series)
{
    series.DataLabels.ShowValue = true;
    series.DataLabels.NumberFormat.FormatCode = "#,##0";
}

builder.Writeln();
builder.Writeln("上图展示了各地区的季度销售对比,可以清晰看出华东地区表现最佳。");

doc.Save("动态数据图表.docx");

11.3 图表高级格式化

图表美化和自定义样式

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// 创建专业样式的组合图表
builder.Font.Size = 18;
builder.Font.Bold = true;
builder.ParagraphFormat.Alignment = ParagraphAlignment.Center;
builder.Writeln("企业财务分析图表");
builder.Font.Bold = false;
builder.Font.Size = 12;
builder.ParagraphFormat.Alignment = ParagraphAlignment.Left;
builder.Writeln();

// 收入趋势图
Shape revenueChart = builder.InsertChart(ChartType.Line, 450, 250);
Chart chart1 = revenueChart.Chart;

chart1.Series.Clear();
ChartSeries revenueSeries = chart1.Series.Add("月收入",
    new string[] { "1月", "2月", "3月", "4月", "5月", "6月" },
    new double[] { 180, 220, 195, 280, 315, 350 });

// 美化折线图
revenueSeries.Format.Line.Color = Color.Blue;
revenueSeries.Format.Line.Weight = 3.0;
revenueSeries.Marker.Symbol = MarkerSymbol.Circle;
revenueSeries.Marker.Size = 8;
revenueSeries.Marker.Format.Fill.ForeColor = Color.Red;

// 设置数据标签
revenueSeries.DataLabels.ShowValue = true;
revenueSeries.DataLabels.Font.Size = 10;
revenueSeries.DataLabels.Font.Bold = true;
revenueSeries.DataLabels.NumberFormat.FormatCode = "¥#,##0万";

chart1.Title.Text = "月度收入趋势";
chart1.Title.Font.Size = 14;
chart1.Title.Font.Bold = true;

// 设置图表背景
chart1.PlotArea.Format.Fill.PresetTextured(PresetTexture.Parchment);

builder.Writeln();

// 支出结构饼图
Shape expenseChart = builder.InsertChart(ChartType.Doughnut, 300, 300);
Chart chart2 = expenseChart.Chart;

chart2.Series.Clear();
ChartSeries expenseSeries = chart2.Series.Add("支出结构",
    new string[] { "人工成本", "营销费用", "研发投入", "管理费用", "其他" },
    new double[] { 45, 25, 15, 10, 5 });

// 设置饼图颜色
Color[] pieColors = { Color.LightBlue, Color.LightGreen, Color.LightYellow, Color.LightCoral, Color.LightGray };
for (int i = 0; i < expenseSeries.DataPoints.Count; i++)
{
    expenseSeries.DataPoints[i].Format.Fill.ForeColor = pieColors[i % pieColors.Length];
    expenseSeries.DataPoints[i].Format.Stroke.ForeColor = Color.White;
    expenseSeries.DataPoints[i].Format.Stroke.Weight = 2;
}

// 设置数据标签显示百分比
expenseSeries.DataLabels.ShowPercentage = true;
expenseSeries.DataLabels.ShowCategoryName = true;
expenseSeries.DataLabels.Separator = "\n";
expenseSeries.DataLabels.Font.Size = 10;

chart2.Title.Text = "支出结构分析";
chart2.Title.Font.Size = 14;
chart2.Title.Font.Bold = true;

builder.Writeln();
builder.Writeln("以上图表展示了企业的收入增长趋势和支出结构,为决策提供数据支持。");

doc.Save("专业图表样式.docx");

11.4 SmartArt 图形处理

SmartArt创建和编辑

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.Font.Size = 16;
builder.Font.Bold = true;
builder.Writeln("组织架构与流程展示");
builder.Font.Bold = false;
builder.Writeln();

// 注意:Aspose.Words对SmartArt的支持有限,主要是读取和基本操作
// 更复杂的SmartArt通常需要在Word中创建,然后通过Aspose.Words处理

builder.Writeln("项目管理流程:");
builder.Writeln();

// 使用形状模拟SmartArt效果
CreateProcessDiagram(builder);

builder.Writeln();
builder.Writeln();
builder.Writeln("团队层级结构:");
builder.Writeln();

CreateHierarchyDiagram(builder);

doc.Save("SmartArt示例.docx");

SmartArt模拟实现

最佳实践建议

1. 图表设计原则

  • 数据准确:确保数据来源可靠,计算正确
  • 类型选择:根据数据特点选择合适的图表类型
  • 简洁清晰:避免过于复杂的设计,突出关键信息

2. 样式规范

  • 色彩一致:使用统一的配色方案
  • 字体规范:保持字体大小和样式的一致性
  • 比例协调:图表尺寸与页面布局协调

3. 数据处理

  • 数据验证:处理前验证数据的完整性和准确性
  • 格式统一:数值格式、日期格式等保持一致
