Hi all, first of all many thanks for all your comments an suggestions to the Excel-spreadsheet "Analemmatc Sundial".
There is now a new test version of the spreadsheet on my homepage. The main change is Anselmo's idea of introducing an inclining gnomon for generating different types of dials. The gnomon inclination for a "usual" analemmatic sundial is 90 deg. Graphics in Excel are very easy to generate, but here you can see some problems or limits, because the different sundial types look very different too, and I do not now how to fix the text positions with the changing values of the points. For a better adaption in the graphic charts a more complex software language would be useful.Yet, it is funny to see the different dials generated. Have fun Helmut PS: At the moment I am away rather often, so please excuse my late response!
