Basic 2D Graphs with QGraphicsView

**Astronomy** · 3rd August 2009, 19:55

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 ).

Hmm.. they claim to put it under GNU license but want to have a fee?

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.
