Gridviewer improvements

We were able to complete a few substantial improvements to the Gridviewer application. The changes listed below were deployed on the training node (http://ncphi.phgrid.net:8080/gridviewer/):

1. Added download csv extract functionality per query request. (Click on Download Data to get an extract)
   
2. Added HTML data table display with sortable columns per individual query request as well as a combined data set . This feature is currently needing improvements in speed. Further improvements could contain subtotaling by regions or dates. ( Click on Display data link to see control. )
   
3. Corrected bug in the console log with the time displays.
4. Appended build version on the title and header.

Encoded Polygons draw and popup

Most of today was spent making a series of UI tweaks that were requested. Now the legends are adjusted a bit, some extra labels were added, and a link to the help page is on the development version.

I wanted to play with the encoded GMapPolygons before I went home, so I made sure I could replicate the functionality that I already had, and made thus, with the help of Alabama, I now know I can place an encoded gmap polygon with the same click-for-popup and color/shading properties.

Tomorrow will be spent enacting this. I am probably going to try setting up on-the-fly translation, and then work on storing encoded polygons in the database (namely because I can think in my head how to do an on-the-fly translation and there are some tricky bits with database storage of dual strings that I don't want to start there...

Either way, here's to hoping for a vast improvement in performance by tomorrow afternoon.

PopSciGrid

Tom showed me the PopSciGrid by Science of Networks in Communities (SONIC) that he learned about at AMIA.

It's interesting as it is combining multiple data sets over a grid, but also has a rather useful user interface that we might be able to co-opt for the PHGrid UI.
