perhaps thats what I am doing can help you:
I want to plot data that is stored in a file having in the format:
<frequence> <phase> <amplification>
9,99999999999999E+0001 0,00000000000000E+0000 -1,57079632679490E+0000
-1,00000000000000E+0002
1,01157945425990E+0002 7,71721237938515E+0000 -2,14854930109820E-0002
1,77492090458851E+0001
and want to plot the BODE-Diagram. So I did:
myData = ReadList["filename",{Number, Number, Number}];
and now want a plot from <phase> over <frequence> and <amplification>
over <frequence>I tried things like
ListPlot[Transpose[testData][[3]],PlotJoined->True]
but I always got the wrong list-format. I need
{freqence1,phase1},{freqence2, phase2}...
and I always get things like
{phase1, phase2, phase3} or so.
Have you already come so far?
Bye,
Lars
