hi,i use this method for each 100 points plotting:
double x1, y1;
for (int i=0;i<100 ;i++){ x1= .. ; y1=.. ; ui->customPlot->graph(0)->addData(x1,y1);
problem is : i want to keep the last 2000 points. what is the best way for do it?
note: i don't save data points seprate. because i dont use SetData method.
THANK ALL
