How to use Office Web Components to create a chart.

by  Mike Gagnon  Posted    (Edited  )
The following creates a Jpeg picture of a chart you can use in your application on forms, in reports etc... This example sends the chart to the Internet Explorer.
This requires Microsoft's Office Web Components. (http://office.microsoft.com/downloads/2002/owc10.aspx).

Code: 
Local i
Store 0 To i
Dimension laLabels[3]
Dimension laData[3]
Dimension laData2[3]
Create Cursor final (pic m)
Create Cursor sales (Name c(20),total1 N(10),total2 N(10))
Insert Into sales (Name,total1,total2) Values ("Total sales Mike",1000,2000)
Insert Into sales (Name,total1,total2) Values ("Total sales Frank",2550,2500)
Insert Into sales (Name,total1,total2) Values ("Total sales Fred",1292,500)
Go Top
Do While !Eof()
    i = i +1
    laLabels[i]=sales.Name
    laData[i]=sales.total1
    laData2[i]=sales.total2
    Select sales
    Skip
Enddo
loChartSpace = Createobject("OWC10.ChartSpace")
oConst = loChartSpace.Constants
loGraph = loChartSpace.Charts.Add()
loGraph.Type =47
loGraph.HasLegend = .T.
loGraph.PlotArea.Interior.Color="Pink"
loChartSpace.HasChartSpaceTitle = .T.
loChartSpace.ChartSpaceTitle.Caption = "Monthly Sales for My Company Inc."
loChartSpace.ChartSpaceTitle.Font.Bold = .T.
loGraph.SeriesCollection.Add()
loGraph.SeriesCollection(0).Caption = "Sales of widgets #1"
loGraph.SeriesCollection(0).SetData(oConst.chDimCategories, oConst.chDataLiteral, @laLabels)
loGraph.SeriesCollection(0).SetData(oConst.chDimValues, oConst.chDataLiteral, @laData)
loGraph.SeriesCollection.Add()
loGraph.SeriesCollection(1).Caption = "Sales of widgets #2"
loGraph.SeriesCollection(1).SetData(oConst.chDimValues, oConst.chDataLiteral, @laData2)
lcFile = Sys(2023) + "\" + Sys(2015) + ".jpg"
loChartSpace.ExportPicture(lcFile, "jpg",800,600)
oBrowser = CREATEOBJECT("internetexplorer.application")
oBrowser.navigate(lcFile)
oBrowser.visible = .t.
