Main method, draws the canvas and its entire view.

Receives a dataSet data structure and returns a readable array.

optsspeed: 25, amplitude: 10, applyLowPassFilter: true

Read the arraydicombuffer and return legible data.

Read the arraydicombuffer and return information data, example: BPM, Name, Duration ECG...

SOP UID of ECG types and graph measurements.

It is the generic class for the canvas, it contains the values ​​of the number of views, canvas size, rows, columns, grid size...
