Mathematica plot not matching up to excel plot tia sal22 Greetings All I have a set of data values I plot in excel then I create a polynomial so it can be plotted in mathematica. Then I create an audio file using the piecewise function in mathematica. The problem I'm having is when I compare the excel plot and the mathematica plot they don't match up. If your wondering why I use the piecewise function in mathematica it's due to the fact it allows me to create an audio file with it. Is there a better way to do this?
