Re: [science-iwg] SWT XYGraph goes to Eclipse Nebula Visualization

Hi Matt and Peter,

I guess there are some overlaps between your changes and our developments. Could we setup a Google hangout so you can show me your changes and discuss the possible way to adopt your improvements?

Thanks,
Xihui

Hi XiHui,

 

I think our version of swt-xy is from October 2012 – xy-graph 2.1, you can see history here https://github.com/DawnScience/swt-xy-graph.

 

I would suggest that the changes we have are useful to everyone especially the tick mark algorithms created by Peter Chang. Also we added the region system to select things like rectangles, sectors and many other selections. We can then compute mathematics from the selection, work also completed by Peter and myself. Azimuthal/Radial integration by visual selection is possible for instance, this system is generic and useful to all (not just able to do those mathematics!).

 

Therefore if a way can be found to integrate our changes, the plotting will be more powerful. I would have thought that if the IWG thing is going to fly – we need to be collaborating on things like this.

 

That said this is a really good step in the right direction and I am glad that the API has made it to nebula, congratulations a well deserved acceptance of how good xy-graph is.

 

Best Regards,

 

Matt

 

PS Here are the additions we made (from github): We added tick mark algorithms (ability to choose and a new implementation), rendering on linux (removed some off screen drawing), inheritance changes to allow external contributions (used for drawing regions), improvements to visualize large data, a different mechanism for image plotting, several defect fixes, spelling fixes in the public APIs.

 

In future we would like to change the plot preferences UI to have state remembered using eclipse preferences and redesign the UI to be more logical. This work is not too far away.

 

 

Actually I am not the one who made the changes. AFAIK the changes were mainly to improve XYGraph's  2D image display capabilities but there might have been some improvements for performance and bug fixes. Matthew Gerring from DLS can best answer your question.

Hi Andy,

 

No, I'm sorry that I failed to merge the changes from DAWN because there are too many unresolvable conflicts. DAWN's changes are based on a very early version of XYGraph. If possible, you may modify your changes based on the latest version in nebula and I can merge your changes later. BTW, would you please tell me again about the purposes of your changes?

 

Thanks,
Xihui

Xihui,

well done on this excellent work and move to integrate it in Eclipse! The community will be able to continue profiting from your work for a long time now.

BTW are the changes from the DAWN project integrated in the version in Nebula?

Best regards

Andy

Dear folks,

 

I have moved SWT XYGraph from google code to Eclipse Nebula Visualization project: http://www.eclipse.org/nebula/widgets/visualization/visualization.php

 

This project aims to host all scientific visualization related widgets. If you have such widgets want to contribute to Eclipse Nebula, please let me or Wim Jongman (the nebula lead) know.

 

Cheers,
Xihui
