    Default Basic 2D Graphs with QGraphicsView

    Hello

    I've installed Qt Creator 1.2.0, based on Qt 4.5.2 (32 bit)
    For my diploma thesis i need to view some spectroscopic graphs.

    Custom Panel Graph with Line + Symbol Plots of Spectroscopic Data
    http://www.originlab.com/www/product...=28&s=8&lm=215

    My question is:
    Does QGraphicsView provide some sort of gnuplot-like graphs?
    http://gnuplot.sourceforge.net/demo_4.2/

    http://gnuplot.sourceforge.net/demo_4.2/simple.html

    Or Basic Sinus,- plotting functions, scaling Axis, zooming-, scrolling-Axis, setting Labels and tics and so on?

    Or do i have to buiild my own derived QT class, based on QGraphicsView and do it all by myself? (Scaling, Labels, size-resize, and so on..)


    thanx,
    Astronomy

    Qwt offers the type of widgets you asked for. If you are looking for an application like origin check QtiPlot ( what is using the Qwt widget library ).

    AFAIR the fee is for support and packaging only. On Linux systems this is of no relevance because you have packages from your distributor - on Mac and Windows it means you have to build QtiPlot yourself.
