qtdata.cht missing in the tutorial example Item View Examples -> Chart

[dandanch]

Someone ever tried this example?
Also, actually I'd like to draw a graph for some data, like the function provided by Excel.
Someone can give me any hints about which library I should use? Should I use OpenGL?

Thanks!

Yep. And the qtdata.cht file is there at least for me (Qt 4.2.1).. :)
I attached the file shipped along with qt-win-opensource-src-4.2.1.zip.

Sounds like a job for Qwt (http://qwt.sourceforge.net/) or wysota's Charts (http://www.wysota.eu.org/charts.html).

Unfortunately Charts are far from being complete (or even mature):) But they are closer to what Excell offers than Qwt. If you need something in particular, maybe I can add it quickly.
