Hello, We have some OWC code running on a classic ASP page using OWC charts. The code has run fine in Production under Windows Server 2000 and OWC 10. The server is being replaced by Windows Server 2003. We now are using OWC 11. We updated the code to use the OWC11 namespace. We now encounter an error using the NumberFormat Property. We are trying to display numeric percentages along the y axis. This code runs fine on OWC 10. The last line of code(assigning the NumberFormat) gives the following error message: Microsoft Office 2003 Web Components error '80004005' Invalid Parameter ' Create a Chart Object Set oChart = CreateObject("OWC11.ChartSpace") Set c = oChart.Constants ' Add a chart Set cht = oChart.Charts.Add() 'set type of chart cht.Type = c.chChartTypeColumnClustered ' Set the different parameters for the ChartSpace oChart.Border.Color = c.chColorNone ' Get Organization number and use it to set the Caption 'nOrg = nData/5 sCaption = strChart 'oChart.Charts(0).Type = oChart.Constants.chChartTypeSmoothLineMarkers 'add first series oChart.Charts(0).SeriesCollection.Add oChart.Charts(0).SeriesCollection(0).Caption = sCaption 'add second series oChart.Charts(0).SeriesCollection.Add oChart.Charts(0).SeriesCollection(1).Caption = sCaption2 'set categories for each series (same in this case) oChart.Charts(0).SeriesCollection(0).SetData c.chDimCategories, c.chDataLiteral, Categories 'set values for first series oChart.Charts(0).SeriesCollection(0).SetData c.chDimValues, c.chDataLiteral, Vals 'oChart.Charts(0).SeriesCollection(0).Scalings(c.chDimValues).Maximum = 3 oChart.Charts(0).SeriesCollection(0).Scalings(c.chDimValues).Minimum = 0 Dim axs Set axs = oChart.Charts(0).Axes(1) axs.Font.Name = "arial" 'this would appear under the chart 'axs.HasTitle = True 'axs.Title.Caption = "Locations" dim yxs Set yxs = oChart.Charts(0).Axes(0) axs.Font.Name = "arial" yxs.HasTitle = True yxs.Title.Caption = strChart yxs.NumberFormat = "###%" Thanks in advance.
