创建从DataGridView

Question

图表我有DataGridView形式（2列：PartnerName，Adult）

请，我需要从DataGridView填写的数据以图表和打印图表

Answer 1

你可以从以下代码得到想法：

private void DataGridBinding_Load(object sender, System.EventArgs e) 
{ 
    // Populate series data using random data 
    double[] yValues = { 23.67, 75.45, 60.45, 34.54, 85.62, 32.43, 55.98, 67.23 }; 
    for(int pointIndex = 0; pointIndex < yValues.Length; pointIndex++) 
    { 
    chart1.Series["Series1"].Points.AddXY(1990 + pointIndex, yValues[pointIndex]); 
    } 

    // Export series values into DataSet object 
    dataSet1 = chart1.DataManipulator.ExportSeriesValues("Series1"); 

    // Data bind DataGrid control. 
    SeriesValuesDataGrid.DataSource = dataSet1; 

    // Set Series name for data 
    SeriesValuesDataGrid.DataMember = "Series1"; 

} 

private void SeriesValuesDataGrid_CurrentCellChanged(object sender,System.EventArgs e) 
{ 
    // Initializes a new instance of the DataView class 
    DataView firstView = new DataView(dataSet1.Tables[0]); 

    // Since the DataView implements IEnumerable, pass the reader directly into 
    // the DataBind method with the name of the Columns selected in the query  
    chart1.Series["Series1"].Points.DataBindXY(firstView,"X",firstView,"Y"); 

    // Invalidate Chart 
    chart1.Invalidate(); 
} 

您可以从Samples Environments for Microsoft Chart Controls 中获取完整的项目代码，并从WorkingWithData> DataManipulation> Exporting> DataGridBinding部分查找代码。
