OpenOffice Automation Delphi comment créer un diagramme dispersé à partir de colonnes non adjacentes

Question

quelqu'un peut m'aider s'il vous plaît sur la façon de créer un diagramme XY à partir de colonnes non adjacentes? Je veux le faire dans Delphi en utilisant l'interface OOoTools.pas. C'est le code de travail où je ne peux que sélectionner des colonnes adjacentes: L'utilisateur The_Fox m'a beaucoup aidé avec quelques problèmes que j'avais, merci pour cela.

procedure TForm1.ProcessNewChart(aFilename: String); 
Var 
        oTheFile, oAllSheets, oMySheet, oCharts, oChart, 
        oCellRangeAddress, oRectangle, oSize, oChartDoc, 
        oTitleTextShape, oDiagram, oMySymbolType : Variant; 
begin 
ConnectOpenOffice; 

    (* Get a handle to the file *) 
    oTheFile := OpenSheet(aFilename, True); 
    (* Get a handle to the sheets of the Calc file *) 
    oAllSheets:= oTheFile.Sheets; 

    (* Select the first sheet to work with *) 
    oMySheet:= oAllSheets.getByIndex(0); // first sheet of the spreadsheet 

    (* Create a handle to the the charts object *) 
    oCharts := oMySheet.getCharts; 

    (* Specify the position and dimensions of the to be created chart *) 
    oRectangle := oMySheet.Bridge_GetStruct('com.sun.star.awt.Rectangle'); 
    oRectangle.X  := 8000; // X position 
    oRectangle.Y  := 1000; // Y position 
    oRectangle.Width := 15000;// width 
    oRectangle.Height := 5000; // height 

    (* Specify the Cell ranges where to create a chart from 
    The first column specifies the X axis 
    The rest specifies the Y values 
    The first row specifies the labels of the series 
    *) 
    oCellRangeAddress :=  oTheFile.Bridge_getStruct('com.sun.star.table.CellRangeAddress'); 
    oCellRangeAddress.Sheet  := 0; // First sheet of the file 
    oCellRangeAddress.StartColumn := 1; // was 10 
    oCellRangeAddress.StartRow := 6; 
    oCellRangeAddress.EndColumn := 10; 
    oCellRangeAddress.EndRow  := 71; 

    (* Create the Chart *) 
    oCharts.addNewByName('MyGraph',oRectangle,VarArrayOf(oCellRangeAddress),True, True); 

    (* Now place the chart on the sheet *) 
    oChart := oCharts.getByName('MyGraph').EmbeddedObject; 

    (* Set The chart type (scatter) *) 
    oChart.Diagram := oChart.createInstance('com.sun.star.chart.XYDiagram'); 

    (* Turn the symbol of the data points off *) 
    oChart.Diagram.SymbolType := -3; 
    (* Set the spline method 0=none, 1 is cubic and 2 = spline B *) 
    oChart.Diagram.SplineType := 0; 

    (* Set the color of the font *) 
    oChart.Diagram.wall.FillColor := RGB(150,150,150); 

    (*Set the maximym Yaxis value*) 
    oChart.Diagram.YAxis.Max := 40000; 

    (* Set a Y axis title *) 
    oChart.Diagram.HasYAxisTitle := True; 
    oChart.Diagram.YAxisTitle.string := 'Values'; 

    (* Set an X axis title *) 
    oChart.Diagram.HasXAxisTitle := True; 
    oChart.Diagram.XAxisTitle.string := 'Logged Points'; 

    (* The first row contains the names of the columns *) 
    oChart.DataSourceLabelsInFirstColumn := False; 
    oChart.DataSourceLabelsInFirstRow := True; 

    (* Rotate the X axis values *) 
    oChart.Diagram.XAxis.TextRotation := 9000;// '90 degrés 

    (* Set the character height of the labels *) 
    oChart.Diagram.YAxis.CharHeight := 8; 
    oChart.Diagram.XAxis.CharHeight := 8; 

    (* Set The main title and color of the graph *) 
    oChart.HasMainTitle := True; 
    oChart.Title.String := 'VPC logged data visualization'; 
    oChart.Title.CharColor := RGB(200,0,0);

Je pense que vous pouvez le faire en spécifiant plus de 1 CellRangeAddress (notez que vous pouvez donner un tableau de CellRangeAddresses en addNewByName).

Donc je pense:

//labels for columns 
oCellRangeAddress1 :=  oTheFile.Bridge_getStruct('com.sun.star.table.CellRangeAddress'); 
oCellRangeAddress1.Sheet  := 0; // First sheet of the file 
oCellRangeAddress1.StartColumn := 1; 
oCellRangeAddress1.StartRow := 6; 
oCellRangeAddress1.EndColumn := 1; 
oCellRangeAddress1.EndRow  := 71; 

//x-values 
oCellRangeAddress2 :=  oTheFile.Bridge_getStruct('com.sun.star.table.CellRangeAddress'); 
oCellRangeAddress2.Sheet  := 0; // First sheet of the file 
oCellRangeAddress2.StartColumn := 3; 
oCellRangeAddress2.StartRow := 6; 
oCellRangeAddress2.EndColumn := 3; 
oCellRangeAddress2.EndRow  := 71; 

//first range of y-values 
oCellRangeAddress3 :=  oTheFile.Bridge_getStruct('com.sun.star.table.CellRangeAddress'); 
oCellRangeAddress3.Sheet  := 0; // First sheet of the file 
oCellRangeAddress3.StartColumn := 5; 
oCellRangeAddress3.StartRow := 6; 
oCellRangeAddress3.EndColumn := 5; 
oCellRangeAddress3.EndRow  := 71; 

//second range of y-values 
oCellRangeAddress3 :=  oTheFile.Bridge_getStruct('com.sun.star.table.CellRangeAddress'); 
oCellRangeAddress3.Sheet  := 0; // First sheet of the file 
oCellRangeAddress3.StartColumn := 7; 
oCellRangeAddress3.StartRow := 6; 
oCellRangeAddress3.EndColumn := 7; 
oCellRangeAddress3.EndRow  := 71; 

//Create the Chart 
oCharts.addNewByName('MyGraph', oRectangle, 
    VarArrayOf([ 
     oCellRangeAddress1, 
     oCellRangeAddress2, 
     oCellRangeAddress3, 
     oCellRangeAddress4]), 
    True, True); 

Notez que les colonnes ne sont pas plus adjacentes (1, 3, 5, 7).
