Re: Plotting Data (Graph) on LLC graphics using Harmony Graphics composer
First, I would recommend you examine the graphics demos that are in Harmony 2.03beta (2.04 is coming) and start by running one of these demos. But it sounds like the hardware you have isn't supported by any of these demos, so you will either have to buy one of the supported configurations or reengineer a demo onto your hardware.
Microchip completely rewrote the documentation for the MPLAB Harmony Graphics Composer for 2.03b and improved it for 2.04.
As far as a graphics widget: No we don't currently have a single widget to do (x,y) plotting. I've seen spectrum analyzer or graphics equalizer plots constructed by stacking vertical progress bars across the display (one bar for every frequency band).
