The resolution on the spectrogram plot is WAY too low

So, Im trying to plot the spectrogram for a time series sampled at 24KHz, but I am interested in the 3-300 Hz range. However, when I run the code below, it returns this plot
spectrogram(datVec,fs,[],[0,300],fs)
%fs being my sampling frequency, datVec being my time series

This frequency resolution is obviously quite low and I am not sure what to do about this. Changing the overlap window has not helped.

Experiment with more elements to your frequency vector, for example:
spectrogram(datVec,fs,[],[3:3:300],fs)
I’m not certain that will do what you want, however it’s always best to experiment.
