I saw plug-in sketchup. file name is excelchart.rb. In Below # -4100 is the value for the Excel constant xl3DColumn. ChartTypeVal = -4100; # Creates OLE object to Excel excel = WIN32OLE.new("excel.application") # Create and rotate the chart excel['Visible'] = TRUE; workbook = cost.Workbooks.Add(); excel.Range("a1")['Value'] = 200; excel.Range("a2")['Value'] = 300; excel.Range("a3")['Value'] = 100; excel.Range("a1:a3").Select(); excelchart = workbook.Charts.Add(); excelchart['Type'] = ChartTypeVal; 30.step(180, 10) do |rot| excelchart['Rotation'] = rot end excelchart2 = workbook.Charts.Add(); excelchart3 = workbook.Charts.Add(); charts = workbook.Charts charts.each { |i| puts i }
