Modify the waves appearances

Share icon

I'm looking for three features:

1. Is there an easy way to display tiff images in greyscale beside averaging the image manually in a second matrix?
2. Is it possible to select the point boundaries of a wave to display, e.g. display only the values between point 100 and 200?
3. Can I change the plot density of a trace, e.g. display only every second or 5th point?

I could write for all of these some functions which would create a duplicate wave with the right properties, but the points above are only for display purposes and I don't want to create every time a duplicate wave If I changed some parameters. Thanks in advance!
1. ImageTransform rgb2Gray should work. Also, if you are starting from an image that is grayscale but appears in 3 identical planes simply extract a single plane as in:

MatrixOP/O gray=rgbWave[][][0]

2. Use SetAxis.

3. Check out ModifyGraph with mask keyword.

Thank you, I was using this before but totally forgot about it after some years.
