Hi Corneau, I appreciate the responses but again I am really looking for a specific answer
1. "This protocol looks interesting but how do I construct messages such that I can see different visualizations of charts?" This question is not being addressed. 2. How can I use an existing interpreter and achieve my goal otherwords again how can I tie all this thing to charts (I just haven't heard any answer related to that)? If I were to write my own interpreter then I might as well create my own UI. It is ok if you guys say it is not possible and I would understand that and probably pick a different route.
