I'm new to python and I'm using it to analyse accelerations from an accelerometer ie. vibration analysis. For that I need to plot 2 types of diagrams: 1) Frequency map; frequency and time on the axis with the amplitudes, 2) Order map; order and time (or RPM) on the axis with respective amplitudes.
The data from the sensor is sampled at 1 kHz and include the accelerations in X,Y and Z, pulses for every shaft rotation and the timestamps (in microseconds).
And this is still weird looking.
The problem is with my code and using scatter, the points overlap. And if I used smaller points, then they look strange when opening the diagram in full screen. Is there any way to get the plots to look better? Whether using the spectrogram() function or using something like scatter() ?
Also, how can I plot the order map? I don't know how to change the data from time/frequency domain to order domain.
Here is a link to understand what I'm trying to implement: https://de.mathworks.com/help/signal/examples/order-analysis-of-a-vibration-signal.html
Much thanks in advance!
