We have another plugin that we will publish soon that may be a bit simpler to follow as it uses a real data source to poll information. In addition, we have plans to write tutorials for that highlight some of the things you mention. In the mean time, if you have specific questions, feel free to post them here or contact me directly and I can give you pointers to get you moving in the right direction.
Thanks for your answer, It would be great when those new ressources will be realeased !!
We spend a lot of times with my collegue in reading documentation and plugin reverse engineering to create a new plugin. I will try to write unofficial tutorials on that website so that others can benefit from our experience.
I am convinced that this framework could even fits student project needs which require simple ploting of data. At this moment the lack of documentation is a barier to its widespread use.
I would certainly have questions to ask you to clarify technicals points. Thanks for you work !
