Hi Riccardo,
the graph in the ClimateCabinet example presents a time bar over a given curve (the heating and cooling process) to indicate the passed time and the preceding time.
Before trying to adapt a certain example, it would be good to define what exactly you want to display. Is it a static curve? Do you want to present some measured values as a graph? Should the graph update as soon as new values are available? Should the graph move? Is the user able to move/zoom the graph? ...
You will find several different examples (Climate Cabinet, Waveform Generator, Pulse Oximeter, Oscilloscope, ...) delivered with Embedded Wizard Studio - each with different types of graphs. Depending on your use-case it might be helpful to study a certain example.
Best regards,
Manfred.
