Memory problem with plot
I am working on software written in c++. It takes input as pressure transducer, and generate graph of pressure, AC, DC, and pitch. This also has scroll back facility after recording. I am storing data object QPointF(float,float) in memory. It's like oscilloscope example with scroll bar facility. But, its consuming memory as graph progresses. So, it just broke after few hundred seconds of recording. Is there any way to improve memory consumption in graph?(any hint will help) its my first post, so might be very broad question. I will try to narrow down eventually.
