Hello Fellows,

Couple of days ago, some fellows at Excel forum helped me to find out maxima of a sine wave. The method also somehow included points that were close to maxima. So I used IF condition to remove such erroneous points (see attachment column D, E and F). I tried to use this data further for my analysis but apparently I cannot do it until I remove all the rows with zeros in it like row # 6, 7 and 8. Please suggest some procedure to carry out this task.

Secondly, I have plotted voltage maxima vs. time steps. I want a plot without blue curve (time) and x-axis with time stamps 0.0094, 0.0442 and 0.0788 instead of 1, 2 and 3.

Third, If I want to hide coulmns D, E and F using a 'plus' sign to expand or hide these columns, how I can do it?

Any help and suggestion will be much appreciated, thanks in advance!!
