Qwt Realtime plotting

Hii,

I'm new to QT and QWT. I'm doing an application using QT and QWT; I need x Axis as time stamp, y axis as data. The data [eg: Roll and Pitch] is reading from the .bin file and I want to plot wrt to time stamp every 40msec. How I will do it? I'm not understanding the QWT examples.. Anybody is having the same kind of application please send to me..

Thanks

Have u seen the CpuPlot example in qwt? It is a real time plot and is pretty simple and easy
