In a study involving real-time data plotting, it was found that 50% of the graphs, specifically those for FFT and PSD, failed to display on the first attempt. The data, sourced from a serial port, was used to plot two types of graphs: ECG and FFT/PSD. The ECG graphs successfully plotted in real time, whereas the FFT/PSD graphs only displayed after the second data reading. This issue persisted despite the data being correctly received and processed. The study highlighted that while the ECG plot updated continuously, the FFT/PSD plot remained blank during the initial data input. This statistical anomaly underscores the challenges in real-time data visualization and the need for further investigation into plotting techniques.

Apr 8 I just spent two hours banging my head against the wall trying to get something to work. I then had a friend watch me try to fix it. First thing I did with him watching was I restarted the program. That fixed it. Sigh.
