I am new to QCustomPlot. I want to make real time plot using QCustomPlot in Android .I am experimenting with performance of realTimeDemo. It works great in a desktop environment (Win7, i7 Processor) with 550+FPS. However in Android 4.2 with dual core processor, it is approx. 40FPS. So it creates clear lag in plotting . Minimum expected is 60 FPS. Please suggest, how can it be improved. Thanks in advance.
