I don't understand your explanation. You want to clone a plot to end up with 50 widgets in the end? Or do you just need an image of a plot so that you can save it somewhere?

I need an image and all points from thess widgets (X,Y, and timestamp). I want to print all dates and images.
I have points for 5 min but just 5 plots to draw these points. I draw the first 10 sec in Plot 1 (0 to 10 sec), then Plot 2 (10 to 20 sec) and so on. The dates from 50 sec can I draw in Plot 1. A Circular buffer but with Plots. Use can see the last 5 Plots, but others images and tables of points (X,Y, Timestamp) are in memory located

Use QwtPlotRenderer to render a plot to an image, store the image somewhere and reuse the plot object.
