Qt Charting Component - Feedback request

ZapB

Woohoo! I've just managed to get the basic plot example (shown above running in the simulator) to run natively on Symbian^3. This feels like a major step for me and it shows that we can now relatively easily create applications containing charts on desktop, embedded and mobile targets. :D

The only changes I made compared to the same example built for desktop was to make the font size a little smaller to make better use of the available space and to call QWidget::showFullScreen() rather than QWidget::show() on the QGraphicsView. I'll try to factor the font size adjustments into the library. The choice between show() and showFullScreen() is down to the application writer.

Looks amazing can't wait to try it out :)

ZapB

Thanks Zester. Not too long now hopefully.

"This question":http://developer.qt.nokia.com/forums/viewthread/6950/ was split off as a separate topic.

Can't wait to give it a try! Great work.
Any idea when we shall have the chance to play with it?

ZapB

Thx rafy. A few months I expect. I am working on the last couple of features for version 1.0 then I need to do lots of code tidy up and bug fixing ;-) As always my time is limited though.

Great work, Sean, i do really like your Charting Component :D

ZapB

I now have the basics of contour plots working too. At the moment it just uses the Henry Ford colour scheme though so still work to do on making them look blingtastic ;-)

Hey Sean,

Impressive work!

Charttypes that I miss in your list are the financial stock charts like bar charts (open, high, low, close) and candlestick charts. I know that many developers are looking for something like that. I am using qwt for that purpose but it does not support these types either.

It would be great to have these as well.

Kind regards,
Eric

Hi Eric, I have financial stock charts on my todo list but probably not for version 1.0. The good news is they should be very simple to add in.

emiddelkoop

Ok good. Can't wait for your first release.

Sean,

Bump.

How can I use your widget from within QML?
Can I draw xy science plots using data from a C++ class (say a std::vector) ?
In my app, the data may arrive any time, so how can I notify the plot widget to draw the new data?
Is there an example ?

Thank you for the great work. It seems what a lot of people have been waiting for!

rafy

How is it going on with version 1.0? Can't wait to play with it.
Raph

Hey Guys,

sorry for the delays on this. I'm in the middle of changing jobs and things are very hectic still at my existing job. I hope to get version 1.0 out very soon now.

Victor: I am playing around with an idea on how to integrate this into QML 1. As for QML 2 I am not sure what is the best route to go down as yet so that requires some more experimentation.

andre

Just wondering... will this project clash with the product portfolio of your new employer?

ZapB

Potentially yes. Something to be resolved...

Victor

Thanks for the update.

If you need a guinea pig I would enjoy helping. QML2 is fine.

BTW, Good Luck with your new position! I know how crazy that can be.

rafy

Are you still working on the project?
I hope so!

Anything new on this?
I'm really keen on playing with it.
