Hello, in this article we will create a JS dashboard with 2D and 3D spectrogram charts.

The purpose of creating this project is to explain how to create a vibration analysis application that allows us to check sound waves using 2D and 3D spectrogram charts that LightningCharts JS provides us with its lcjs library.

Vibration analysis is of great importance in detecting errors and/or faults in industrial equipment (just to mention one example).

I once worked in the industry and I remember that it was possible to detect failures in relief valves, air coolers, and compression elements, simply by listening to the intensity of the sound they generated.

With the chart that we are going to build next, we will see an audio file corresponding to a similar case.

Large companies in the motorsports industry are collecting huge volumes of real-time data coming from different sources on and off the pitch during racing competitions.

These data are both collected from the car and the car engine itself and are meant to help drivers and engineers to understand the behavior of the machine in a dynamic environment.

Understanding the behavior of the vehicle during a race is key to making improvements in the performance of the entire racing team (such as Formula 1 teams!). High-performance data visualization in motorsports can lead a team to an improvement in performance during a race.

When you think about vibration analysis, what comes to mind? It is becoming a very common identification method in structural engineering to identify issues with potential structural integrity, such as hidden objects or voids.
