Generating signal as shown in the image in labview

[GoviRe]

Is there a way of changing the vi so that it can detect the red lined(signal) in the image because i got this image from a report which has a red waveform.I don't know hwo to change it to red.

can someone help me out in modifying the vi attached in my last post to make it work with the red line image as now it is working with only white line in the image.

Is there someone that can help me out in modifying the attached vi so that it will work with the detection of the red lined(signal) image(attached as notworking image) as it is currently working with the white lined(signal) image(attached as working image) .

or is there any other alternative to change the red line in the image to white line.

How about using a 4 bit pixmap. The "colors" output is a list of 16 colors. The pixmap is a 2d array of those color numbers. Colors 3 and 10 catch most of the waveform.
