Yesterday I installed qwt and qt to make programms. I use qwt 6.0.1 and qt 4.8.1. I have QwtPlot which draw the graph and QwtPlotCurve consisted of points. For beginning I setSamples into QwtPlotCurve, then I attach it into the QwtPlot. Then my program will get the online datas from the server. So I couldn't find the methods of QwtPlotCurve in the manuals which add this online datas without the repainting every last points. How should I do it??? If it is not possible, can I create a lot of (about millions) QwtPlotCurves and add they into QwtPLot. Does QwtPlot let me do it??? And the third question, how can I bind several QwtPlotCurves. For example, I have QwtPlotCurve c1,c2, then I set datas into c1 and c2, and at the end I'd like to bind c1(last point) and c2(the first point) with the line. Thank you for your attentions.Please, help me)))

I see that this is a very weak point of qwt. I asked this questions in the a lot of forums(((
