Hi everyone.
Can you help me on how I can obtain this type of graphs (see example), which represent amplitude variations at a certain frequency with respect to time. Note that the Y axis is in logarithmic. A small sample of my data is:
Date time Freq Amplitude
2010/01/01 00:00 0.109864 2.04021
2010/01/01 00:00 0.122071 2.8937
2010/01/01 00:00 0.134278 2.84502
2010/01/01 00:00 0.146485 2.92267
2010/01/01 00:00 0.158692 3.11156
2010/01/01 00:00 0.170899 3.41533
2010/01/01 00:00 0.183107 3.10193
2010/01/01 00:00 0.195314 3.32969
