Origin Ver. and Service Release (Select Help-->About Origin): Origin 2015
Operating System: windows 7
Hi,
Currently we have our graphs successfully created, and is there an easy way to simply add moving average graph onto the existing graph with, let's say 100 points?
Thanks and best regards!

Hi,
Perhaps your best bet is to perform a moving average on the original data within the worksheet itself. Then plot that data along with the original data.
Add a new column to the worksheet and in the F(x)= row, use this function:
movavg(vd,back,forward)
Where vd is the source column (e.g. col(B)) and back and forward are the windows.
For example:
movavg(col(B),100,100)
I hope this helps.
Thanks,

Hi Chris,
Yep, this way works also.
Nice weekend!
Best regards!

Hi CQY,
You can also run the adjacent averaging smoothing ("Analysis> Signal Processing> Smoothing" menu)
directly on the plot as it is essentially the same to the moving averaging (by movavg function),
though there have a few minor differences as follows:
- movavg function can control averaging with both back and forward offsets. In the case of adjacent
averaging, back=forward, and "Points of Window"=(back+forward+1).
- Adjacent averaging has the "weighted average" option, and movavg doesn't have this option.

- Adjacent averaging has the "boundary condition" option (though None may be a typical choice), and
movavg doesn't have this option.

Hope this helps additionally.

P.S. As this is a post in LabTalk forum, if you want to use the adjacent averaging, you can use
"smooth" x-function in your LabTalk code..
