You can use the Name-Value pair argument ‘FrequencyLimits’ to specify the range of frequencies you want to display. The value is specified as a two-element vector with positive strictly increasing entries.
You can use the following line of code where ‘minFreq’ and ‘maxFreq’ specifies the lower and upper limits of the frequency range:
cwt (x, fs, ‘FrequencyLimits’, [minFreq maxFreq]);
Please refer to the following link for more details on the usage of ‘FrequencyLimits’:
