well, Hussein. Could you see whether you can see the SawtoothWave with steps below?
1. Select Analysis: Fitting: Nonlinear Curve Fit from the Origin menu
2. In the opened dialog, select Category as Waveform and select Function as SawtoothWave as image blow

Sorry I am beginner
I don't know where to find it or call it to fit on my data.
I have origin 9.1. But I don't see any Sawtooth wave form in waveform menu.

Hi,
You can try "PWL2" function under "piecewise" category to fit a single arbitrary triangular wave.
Or use "SawtoothWave" function under "Waveform" to fit sawtooth wave.
