SIGGEN syntax
Syntax is (without the spaces):
function amplitude +/- y-offset @ period +/- x-offset (in seconds)
e.g. sin10-30@600-3600 — sinewave of amplitudes -10 and 10; offset by -30 (i.e. between -40 and -20); period of 600 seconds; offset by -3600 seconds (1 hr)*
Function supported are:
- sin (sine)
- cos (cosine)
- saw (saw wave)
- sq (square wave)
- sc (S-curve)
To create just static trends of a single number write
siggen/7
Tip if you would like to trend it you need to place it in a valid calc function. (eg ADD)
eg calc/ADD(siggen/sin4@300,2)
eg calc/ADD(siggen/saw1000000@30d+5d) - Max of 1000000 starting at 0, 30 days off set by 5d (note -5d is invalid)
calc/ADD(rand20~1@2000000)
