在界面中拖入一个ChartControl控件，然后添加一个simplebutton控件。在simplebutton控件的click事件中加入如下代码：

private void button1_Click(object sender, EventArgs e)
        {
            //数据源
            chartControl1.DataSource = CreateChartData();
            //数据成员
            chartControl1.SeriesDataMember = "DWMC";
            //下面显示
            chartControl1.SeriesTemplate.ArgumentDataMember = "DWMC";

chartControl1.SeriesTemplate.ValueDataMembers.AddRange(new string[] {"Value"});

chartControl1.SeriesTemplate.View = new StackedBarSeriesView();
            chartControl1.Titles.Add(new ChartTitle());
            chartControl1.Titles[0].Text = "道路类型统计图";

}

private DataTable CreateChartData()
        {
           
            IWorkspaceFactory pWorkspaceFactory = new  ShapefileWorkspaceFactory();//此处打开的shp 格式的数据
            //IWorkspaceFactory pWorkspaceFactory = new OleDbFactory();
            IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(@"D:\我的文档\道路边线", 0);
            IFeatureWorkspace pFeatureWorkspace = pWorkspace as IFeatureWorkspace;

int ZCityRoadNum = 0, CCityRoadNum = 0, NRoadNum = 0, DXBGNum = 0, NullNum = 0, CDNum = 0;//城市道路（主干道）、城市道路（次干道）、内部道路、单线标准轨、空、车档

if (pFeatureWorkspace != null)
            {
                IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass("道路边线");
                IQueryFilter filter = new QueryFilterClass();
                filter.WhereClause = null;
                IFeatureCursor pFeatureCursor = pFeatureClass.Search(filter,false);
                IFeature pFeature = pFeatureCursor.NextFeature();
                string value = null;
                while (pFeature != null)
                {
                    int index = pFeatureClass.FindField("DWMC");
                    if (index != -1)
                    {
                        value = pFeature.get_Value(index).ToString();
                    }
                    if (value.Trim() == "城市道路(主干道)")
                    {
                        ZCityRoadNum++;
                    }
                    if (value.Trim() == "城市道路(次干道)")
                    {
                        CCityRoadNum++;
                    }

                    {

                    }
                    if (value.Trim() == "单线标准轨")
                    {
                        DXBGNum++;
                    }
                    if (value.Trim() == "车挡")
                    {
                        CDNum++;
                    }
                    else
                    {
                        NullNum++;
                    }
                    pFeature = pFeatureCursor.NextFeature();
                }
            }

//建一个空表
            DataTable table = new DataTable("DLBX_DWMC");

//列
            table.Columns.Add("DWMC",typeof(string));

table.Columns.Add("Value",typeof(Decimal));

//行
            table.Rows.Add(new object[]{"城市主干道",ZCityRoadNum});
            table.Rows.Add(new object[]{"城市次干道",CCityRoadNum});
            table.Rows.Add(new object[]{"内部道路", NRoadNum });
            table.Rows.Add(new object[]{"单线标准轨",DXBGNum });
            table.Rows.Add(new object[]{"车挡",CDNum});
            table.Rows.Add(new object[]{"无",NullNum});
            return table;
         }
    }
