C# 在PPT幻灯片中创建图表

程序员文章站 2022-05-13 22:37:49
图表能够很直观的表现数据在某个时间段的变化趋势，或者呈现数据的整体和局部之间的相互关系，相较于大篇幅的文本数据，图表更增加了我们分析数据时选择的多样性，是我们挖掘数据背后潜在价值的一种更为有效地方式。在做数据汇报时，常用到PPT幻灯片来辅助工作，下面的示例中将演示如何通过C#编程在PPT幻灯片中创建 ......

图表能够很直观的表现数据在某个时间段的变化趋势，或者呈现数据的整体和局部之间的相互关系，相较于大篇幅的文本数据，图表更增加了我们分析数据时选择的多样性，是我们挖掘数据背后潜在价值的一种更为有效地方式。在做数据汇报时，常用到ppt幻灯片来辅助工作，下面的示例中将演示如何通过c#编程在ppt幻灯片中创建图表。示例中主要介绍了三种图表的创建方法，如下:

1. 创建柱形图表

2. 创建饼状图表

3. 创建混合型图表（柱形图、折线图）

 

使用工具：spire.presentation for .net

ps：下载安装后，注意添加引用spire.presentation.dll到程序，dll文件可在安装路径下的bin文件夹中获取。

C# 在PPT幻灯片中创建图表

【示例 1 】创建柱形图表

步骤 1 ：添加using指令

using spire.presentation;
using spire.presentation.charts;
using system;
using system.drawing;

步骤 2 ：创建一个powerpoint文档

presentation presentation = new presentation();

步骤 3 ：在幻灯片指定位置绘入指定大小和类型的图表

rectanglef rect = new rectanglef(40, 50, 680, 500);
ichart chart = presentation.slides[0].shapes.appendchart(charttype.column3dclustered, rect);

步骤 4 ：添加图表数据

//添加图表名
chart.charttitle.textproperties.text = "2018年上半年销量";
chart.charttitle.textproperties.iscentered = true;
chart.charttitle.height = 30;
chart.hastitle = true;

//定义一个sting[,]数组
string[,] data = new string[,]
 {
  {"产品大类","1月","2月","3月","4月","5月","6月" },
  {"dw10","1542","1057","1223","1302","1145","1336"},
  {"zq13","4587","3658","2515","3154","2984","3890" },
  {"yi73","558","458","369","576","334","482" },
  {"tr11","2011","2485" ,"3010" ,"2785" ,"2225" ,"2476" }
 };

//将数据写入图表后台数据表
for (int i = 0; i < data.getlength(0); i++)
{
    for (int j = 0; j < data.getlength(1); j++)
    {
        //将数字类型的字符串转换为整数
        int number;
        bool result = int32.tryparse(data[i, j], out number);
        if (result)
        {
            chart.chartdata[i, j].value = number;
        }
        else
        {
            chart.chartdata[i, j].value = data[i, j];
        }
    }
}

//设置系列标签
chart.series.serieslabel = chart.chartdata["b1", "g1"];

//设置类别标签
chart.categories.categorylabels = chart.chartdata["a2", "a5"];

//为各个系列赋值
chart.series[0].values = chart.chartdata["b2", "b5"];
chart.series[1].values = chart.chartdata["c2", "c5"];
chart.series[2].values = chart.chartdata["d2", "d5"];
chart.series[3].values = chart.chartdata["e2", "e5"];
chart.series[4].values = chart.chartdata["f2", "f5"];
chart.series[5].values = chart.chartdata["g2", "g5"];

步骤 5 ：应用图表样式

//应用内置图标样式
chart.chartstyle = chartstyle.style12;
//设置系列重叠
chart.overlap = -50;
//设置类别间距
chart.gapwidth = 200;

步骤 6 ：保存文档

presentation.savetofile("柱形图.pptx", fileformat.pptx2010);
system.diagnostics.process.start("柱形图.pptx");

调试运行程序后，生成图表，如下图：

【示例 2 】创建环形图表

步骤 1 ：添加using指令

using spire.presentation;
using spire.presentation.charts;
using spire.presentation.drawing;
using system.drawing;

步骤 2 ：新建一个ppt文件

presentation presentation = new presentation();

步骤 3 ：插入圆环形图表

rectanglef rect = new rectanglef(40, 100, 550, 320);
ichart chart = presentation.slides[0].shapes.appendchart(charttype.doughnut, rect, false);

步骤 4 ：添加图表数据内容

//设置图表名
chart.charttitle.textproperties.text = "市场份额";
chart.charttitle.textproperties.iscentered = true;
chart.charttitle.height = 30;
chart.hastitle = true;

//定义数据
string[] countries = new string[] { "古巴", "墨西哥", "法国", "德国" };
int[] sales = new int[] { 1800, 3000, 5100, 6200 };

//将数据写入图表后台数据表
chart.chartdata[0, 0].text = "国家";
chart.chartdata[0, 1].text = "销售额";
for (int i = 0; i < countries.length; ++i)
{
    chart.chartdata[i + 1, 0].value = countries[i];
    chart.chartdata[i + 1, 1].value = sales[i];
}

步骤 5 ：应用图表标签

//设置系列标签
chart.series.serieslabel = chart.chartdata["b1", "b1"];

//设置分类标签
chart.categories.categorylabels = chart.chartdata["a2", "a5"];

//为系列赋值
chart.series[0].values = chart.chartdata["b2", "b5"];

//添加点到系列
for (int i = 0; i < chart.series[0].values.count; i++)
{
    chartdatapoint cdp = new chartdatapoint(chart.series[0]);
    cdp.index = i;
    chart.series[0].datapoints.add(cdp);
}

//为系列里的个点添加背景颜色
chart.series[0].datapoints[0].fill.filltype = fillformattype.solid;
chart.series[0].datapoints[0].fill.solidcolor.color = color.lightblue;
chart.series[0].datapoints[1].fill.filltype = fillformattype.solid;

//设置标签显示数值
chart.series[0].datalabels.labelvaluevisible = true;

//设置标签显示百分比
chart.series[0].datalabels.percentvaluevisible = true;

//设置圆环内径大小

【示例 3 】创建混合型图表

步骤 1 ：添加using指令

using spire.presentation;
using spire.presentation.charts;
using spire.presentation.drawing;
using system;
using system.data;
using system.drawing;

步骤 2 ：新建文档

presentation presentation = new presentation();

步骤 3 ：创建图表1：柱形图表

//插入柱形图
rectanglef rect = new rectanglef(40, 100, 650, 320);
ichart chart = presentation.slides[0].shapes.appendchart(charttype.columnclustered, rec

//添加表名
chart.charttitle.textproperties.text = "2017季度销售情况";
chart.charttitle.textproperties.iscentered = true;
chart.charttitle.height = 30;
chart.hastitle = true;

//创建一个datatable
datatable datatable = new datatable();
datatable.columns.add(new datacolumn("季度", type.gettype("system.string")));
datatable.columns.add(new datacolumn("销售额", type.gettype("system.int32")));
datatable.columns.add(new datacolumn("同比增长率", type.gettype("system.decimal")));
datatable.rows.add("1季度", 200, 0.6);
datatable.rows.add("2季度", 250, 0.8);
datatable.rows.add("3季度", 300, 0.6);
datatable.rows.add("4季度", 150, 0.2);            

//将datatable数据导入图表后台数据表
for (int c = 0; c < datatable.columns.count; c++)
{
    chart.chartdata[0, c].text = datatable.columns[c].caption;
}
for (int r = 0; r < datatable.rows.count; r++)
{
    object[] datas = datatable.rows[r].itemarray;
    for (int c = 0; c < datas.length; c++)
    {
        chart.chartdata[r + 1, c].value = datas[c];

    }
}

//设置系列标签
chart.series.serieslabel = chart.chartdata["b1", "c1"];

//设置类别标签      
chart.categories.categorylabels = chart.chartdata["a2", "a5"];

//为系列赋值
chart.series[0].values = chart.chartdata["b2", "b5"];
chart.series[1].values = chart.chartdata["c2", "c5"];

步骤 4 ：添加折线图

//将系列2的图表类型改为折线图
chart.series[1].type = charttype.linemarkers;

//将系列2显示到第二根轴
chart.series[1].usesecondaxis = true;

//显示百分比数据
chart.secondaryvalueaxis.numberformat = "0%";

//不显示第二根轴的网格线
chart.secondaryvalueaxis.majorgridtextlines.filltype = fillformattype.none;

//设置系列重叠
chart.overlap = -50;

//设置类别间距
chart.gapwidth = 200;

步骤 5 ：保存文件

presentation.savetofile("混合图表.pptx", fileformat.pptx2010);
system.diagnostics.process.start("混合图表.pptx");
