OWC图表（C#）
OWC.ChartSpace owcChartSpace=new OWC.ChartSpace();
OWC.WCChart owcChart=owcChartSpace.Charts.Add(0);
ADODB.Connection ConnADO = new ADODB.Connection();
ADODB.Recordset RecordsetADO = new ADODB.Recordset();
string connectionString = "Provider=MSDataShape;Data Provider=SQLOLEDB;uid=OAM;pwd=OAM;Data Source=bqsnet;initial catalog=oam";
ConnADO.Open(connectionString,"OAM","OAM",-1);
RecordsetADO.ActiveConnection = ConnADO;
RecordsetADO.CursorType = ADODB.CursorTypeEnum.adOpenStatic;
RecordsetADO.CursorLocation = ADODB.CursorLocationEnum.adUseClient;
string strSQL = "select * from student order by student";
RecordsetADO.Open(strSQL,ConnADO,ADODB.CursorTypeEnum.adOpenStatic,ADODB.LockTypeEnum.adLockReadOnly,0);
owcChartSpace.DataSource=(msdatasrc.DataSource)RecordsetADO;
owcChart.Type=OWC.ChartChartTypeEnum.chChartTypeColumnClustered; //柱状
// owcChart.Type = OWC.ChartChartTypeEnum.chChartTypeSmoothLineMarkers;  //线状
owcChart.SetData(OWC.ChartDimensionsEnum.chDimSeriesNames,0,"student");
foreach (OWC.WCSeries owcSeries in owcChart.SeriesCollection)
{
owcSeries.SetData(OWC.ChartDimensionsEnum.chDimCategories,0,"test");  //X轴
owcSeries.SetData(OWC.ChartDimensionsEnum.chDimValues,0,"score");  //Y轴
}
foreach (OWC.WCAxis axis in owcChart.Axes)
{   //说明表示意义
owcChart.HasLegend=true;
owcChart.Legend.Position=OWC.ChartLegendPositionEnum.chLegendPositionBottom;
// owcChart.Legend.Font.Size=15;
//标题
owcChart.HasTitle=true;
owcChart.Title.Caption="学生成绩表";
//X,Y轴意义
axis.HasTitle=true;
if (axis.Type==ChartAxisTypeEnum.chCategoryAxis)
{
axis.Title.Caption="test";
}
else
{
axis.Title.Caption="score";
}
}
// owcChart.SeriesCollection[1].Interior.Color="red";  //改变颜色
// owcChart.SeriesCollection[1].Line.Color="red";  //改变颜色
Random rd=new Random();
int nfilenameSuffix;
string sfilenamesuffix;
nfilenameSuffix = 100000 * rd.Next();
sfilenamesuffix = Convert.ToString(nfilenameSuffix);
owcChartSpace.ExportPicture(MapPath("../Report/") + sfilenamesuffix + ".gif", "gif", 800, 600);
Image1.ImageUrl = "../Report/" + sfilenamesuffix + ".gif";
在项目引用中加入com中的microsoft office web component9.0组件且引用using OWC
