Dear Laurent, suppose you have two series, "variable1", with the values
"2", and "variable2", with values "1". I think you could
try this:
*<script>*
*series* variable1 = variable1 - 1
*series* variable2 = variable2 - 1
*</script>*
I'd made a mistake :-( Let me try to correct it. Supose you have a variable
that assumes only 2 and 1 as values. So now you can try this:
*<script>*
*series* variable = variable - 1
***</script>*
In that you way all your 2 will become 1 (because 2-1=1) and all your 1 will
become 0 (because 1-1=0). You can try my suggestion, but the Ignacio's
suggestion is much more elegant ;-)
Best regards,
