使用ZedGraph記錄

2013-11-13 09:48:52  來源: .NET編程 

  在網上找了半天終於確定一個工具……ZedGraph
    先在添加引用選擇ZedGraphdll
    然後在工具箱中添加ZedGraph控件
    將控件拖到頁面上
    然後在控件的RenderGraph事件中插入代碼
餅圖代碼
    Code
    GraphPane myPane =  (GraphPane)pane[];
    DataTable dt = ssihGetList(= order by 表A desc
    double tag = ;//看長
    double tag= ;//看中
    double tag= ;//看多
    int j=;
    foreach(DataRow dr in dtRows)
    {
    if(j==
    {
    tag = ConvertToDouble(dr[看長]ToString())*;
    tag = ConvertToDouble(dr[看中]ToString())*;
    tag = ConvertToDouble(dr[看多]ToString())*;
    }
    j++;
    }
    //標題粗體
    myPaneTitleFontSpecIsItalic = true;
    //背景
    myPaneFill = new Fill( ColorWhite ColorWhite f )
    myPaneChartFillType = FillTypeNone;
    //說明文字位置定義
    //            myPaneLegendPosition = LegendPosFloat;
    myPaneLegendLocation = new Location( f f CoordTypePaneFraction
    AlignHRight AlignVTop )
    myPaneLegendIsVisible = false;
    myPaneLegendFontSpecSize =f;
    myPaneLegendIsHStack = false;
    //            PieItem segment = myPaneAddPieSlice( tag ColorRed ColorWhite f 看多 +tagToString(##)+%
    //            PieItem segment = myPaneAddPieSlice( tag ColorWhite ColorWhite f 看平 +tagToString(##)+%
    //            PieItem segment = myPaneAddPieSlice( tag ColorBlue ColorWhite f  看空 +tagToString(##)+%
    折線圖及股票上證指數的K線圖
    Code
    //上證指數k線圖
    DataTable dt = ssihGetList(= order by dataDate asc
    double[] x = new double[dtRowsCount +];

    LineItem myCurve = myPaneAddCurve(看多pp ColorRed SymbolTypeDiamond)
    myPaneAxisChange()
