Open Source Qt Chart Library

[goblincoding]

Good day ladies and gentlemen!

I've started writing a free chart library specifically for use in Qt applications and wish to get the word out. The library is an ongoing project and is being distributed under the GNU LGPL. If this sounds like something you could use or would like to know more about, please visit the project's site for more information:

Critique is not only welcome, but encouraged.

Looking forward to hearing from you.

Hi,

Seems good. You sure get a price for the nicest looking website for a Qt class :-)

You could check out this older thread for some more info : Qt-Charts-API-create-static-and-animating-charts-for-your-application (http://www.qtcentre.org/threads/37703-Qt-Charts-API-create-static-and-animating-charts-for-your-application)

One backdraw of your approach : it doesn't use the model/view approach. That seems like a missed opportunity.

Regards,
Marc

nice work done. I really liked the GUI test app too.

Thank you very much for your replies!

@ marc - I'm definitely going to re-evaluate the library during the process of improving its flexibility (I wish to make it much more dynamic and am planning on drawing heavily on the Qt chart example http://doc.qt.nokia.com/latest/itemviews-chart.html ) so, if it turns out I had a flawed initial design premise, then I'm not beyond entirely rewriting the library :D If you have time to review the code and can think of a way I can improve the abstraction to make the transition to a proper model/view paradigm easier, then please let me know.

Update:

I've replaced the static "proof of concept" application with a more dynamic library. Still limited and not entirely well-tested, but hoping it could already be useful to some (see link in original post).

Slow-going, but much learning happening! :)

Looks better and better.
Keep up the good work !
