I have been pondering some ideas about this very issue. I think there
are some innovative ways we can use AJAX with the XML based SVG
graphics markup to accomplish a flexible charting service on the
client side.

I totally, totally agree. Indeed, in the current design the
Telemetry Analysis Service sends just the data points in XML format
to the TelemetryViewer, which then has responsibility for
generating the chart for display. Presumably this will be done
using JFreeChart, but that's not written in stone.

Just an idea: For the telemetry viewer, I always wanted to shift the
graph rendering responsibility from the server side to the client
side.
The benefit is much more smoother user experience and more
flexible graph
display options. Since Hackystat is going to a service oriented
architecture, probably this is a good opportunity.

I've spent this morning trying to add more details to what we might
want to shoot for in the May 15 milestone. I've updated the
SensorDataViewer project (David) and the TelemetryViewer project
(Pavel) with new home pages and a wiki page with Schedule
information.
Details and links are available at my blog:

Now that I've finally got an initial version of the SensorBase REST
API, I can start to work on implementation!
David and Pavel: please stop by early next week to chat about these
goals and so we can make any modifications necessary.
Alexey: We still have not met to figure out what service you will
focus on. Let's do that soon! Perhaps Dan will want to ruminate on
this as well.
Cheers,
Philip
