what's the best way to fit a cirve and put the fitting curve onto the same waveform?

[IgG]

Hi, all

i have real time data sampling.

i need to fit the data in realtime and add the fitting plot onto the same waveform?
what is the best way to do this??
by the way..i also don't quite understand how to add two plot onto one same waveform?

thank you very much
Jack

Look at attached vi.

It illustrates one simple way of plotting two plots onto one waveform graph

You could do this on an xy graph too

any further doubts , do ask

To fit the data, you need the correct model. What kind of function are you trying to fit? LabVIEW has a large collection of fitting tools. Do you have some example data?

To display multiple plots on the same waveform graph, the techniqe depends on the type of data.

If one plot is a 1D array, you would make multiple plots on the same graph by using "built array" and forming a 2D array.

If one plot is a waveform, use "built array" to make a 1D arra of waveform.

If you have dynamic data, use "merge signals" before feeding it to the graph terminal.

thank you both of you : )
really helpful
