How to hide label "0" from Y axis?

and how to change the type of an existing wave from NUMERIC to TEXT?

thx!!
Double-click on the left axis to open the Modify Axis dialog. Choose the Tick Options tab. Type 0 in the Inhibit ticks box. This would be equivalent to executing the command:
ModifyGraph tickZap(left)={0}


As for your second question: you can't convert a numeric to a text wave. You can create a text wave from a numeric wave, e.g.,
Make/N=(numpnts(numWave))/T myTextWave=num2str(numWave[p])


I hope this helps,
