Consult everybody, want to do data processing, specific as follows: in the notepad (or excle) there are four column data (tens of thousands of lines), the first listed as time axis, the second, three, four as each point in time the corresponding motor data, want to translate them into waveform figure (similar to sine curve) inverse time, longitudinal axis data, and then the curve in a certain period of time point is bad (volatility,) you can manually drag curve, drag again will be processed after the completion of data stored in notepad (or excle) , could you tell me how to implement or player who knows what software can be achieved? Urgent!!
Tried the labview and excel's built-in line chart can't drag line, ask the great spirit guide!!!!!!
