My project requirement is, I used to collect data for days and plot them in qwt......I have no problem in plotting the data..but when i try to zoom, GUI kinda freeze for a second or two and then move into the zommed region.... I literally append million points into curve....Any help quickening the zooming process......
I am using qwt 6.1.0 in my project...I use QwtPlotZoomer for zooming
