Hi, I was trying to categorize my measurement data waves by a text wave, is this done by an If-statement? Or there are other better methods? If by "If', how could I program a conditional statement that will give either true or false based on the text content of that data point in the text wave? Thank you!!
I'm not sure what you are asking but this may give you some ideas:
Function Test(tw)
    Wave/T tw
   
    Variable numPoints = numpnts(tw)
    Variable i
    for(i=0; i<numPoints; i+=1)
        String str = tw[i]
        if (CmpStr(str,"Green") == 0)
            Printf "Point %d is green\r", i
        endif
    endfor
End

Function Demo()
    Make/O/T textWave = {"Red", "Green", "Blue"}
    Test(textWave)
End

Thank you hrodstein! This is exactly what I am looking for!!
