Thanks! That does the trick (Excel 2002). Here's my code for anyone interested:
-- create scatterplot in Excel
local excel = luacom.CreateObject("Excel.Application")
excel.Visible = true
local wb = excel.Workbooks:Add()
local ws = wb.Worksheets(1)
for row=1,100 do
ws.Cells(row,1).Value2 = math.random()
ws.Cells(row,2).Value2 = math.random()
-- note: using ".Value2" since ".Value" fails
-- with type mismatch error. why?
local chart = excel.Charts:Add()
chart.ChartType = -4169 -- scatter XY
chart.HasLegend = 0
local range = ws.UsedRange
Some data type issue:
-- "The only difference between [the Value2] property and the Value property is
that the Value2 property doesn’t use the Currency and Date data types. You can
return values formatted with these data types as floating-point numbers by using
the Double data type."
I guess I'll work on patching luacom to get it to compile in lua 5.1 now.
