Hi!
Is there a way to swap x and y axis in lower subplot – spectrogram? Script for spectrogram is generated from Signal Analyzer app.
I need frequency on horizontal axis and time on vertical axis.
timeLimits = [0 3.981311]; %[s]
frequencyLimits = [0 120000]; %[Hz]
overlapPercent = 50;svetlobni_tok_ROI = svetlobni_tok(:);sampleRate = 1000000; %[Hz]startTime = 0; %[s]figure(2)%FFT
minIdx = ceil(max((timeLimits(1)-startTime)*sampleRate,0))+1;maxIdx = floor(min((timeLimits(2)-startTime)*sampleRate,length(svetlobni_tok_ROI)-1))+1;svetlobni_tok_ROI = svetlobni_tok_ROI(minIdx:maxIdx);subplot(2,1,1)pspectrum(svetlobni_tok_ROI,sampleRate,'FrequencyLimits',frequencyLimits);%Spectrogram
timeValues = startTime + (0:length(svetlobni_tok_ROI)-1).'/sampleRate;minIdx = timeValues >= timeLimits(1);maxIdx = timeValues <= timeLimits(2);svetlobni_tok_ROI = svetlobni_tok_ROI(minIdx&maxIdx);timeValues = timeValues(minIdx&maxIdx);subplot(2,1,2)pspectrum(svetlobni_tok_ROI,timeValues,'spectrogram','FrequencyLimits',... frequencyLimits,'OverlapPercent',overlapPercent);
