Select Moodle version:

Blocks: Dashboard

block_dashboard
Graphic, one query dashboard element using MIT library JQplot and other libraries
Maintained by: Picture of Valery Fremaux Valery Fremaux

the dashboard element bloc is of use with flexible Moodle
page formats allowing free setup of the dashboard page layout using blocks.

It implements a "dashboard element" capable to plot and render in
many graphic output formats any result of a complex query presented
to the Moodle database (or an eventual external PostGre schema).

Given a full query, the dashboard block mashes up :

- Data table output
   + Linear (records) data table
   + Tabular (cross dimension) tables
   + Treeview (on hierarchical mapped results)
   
- Graphic plotting using JQPlot
   + Line graphs
   + Bar graphs
   + Pie graphs
   + Donuts graphs
   
- Geographic plotting (using GoogleMaps API)
   + Google Maps + query data plotting
   + Possibility to change icons and plor mutiple class data using course files
   + Geocoding requests to Google handled (up to 2500 per day) with static long term caching
   => Will evolve

- Time special plotting : Integrating SIMILE Timeline plugin
   + Plot on a timeline plugin of "instant" and "time duration" events
   + possibility of setting up color classes for events
   + possibility to customize "instant" pin icons from course files
   => Will evolve

- Data output additional features
  + Data output formatting (using sprintf formatting)
  + Filters (selecting output or query fields for filtering)
  + Summators : displaying computed sums of output fields
  + Cumulative mode : Produces cumulative sum of a field without extra query
  + Data colouring and marking (on tables) using comparison formulas (ex: %% == 0 )
  + Mappable Labels for ALL query field names

- Performance features
  + Result caching (programmable retension delay)
  + Croned refresh of cache
  + Instance adjustable refresh mode or global cron settings

    Data tables have been renamed shorter and more consistent.
    Last post raised a translation value string error (without explicit notice) that seeems not harm the plugin.

    I can not register on your site! Where can I see an example of a query in your pictures?

    Hey Valery, your block sounds nice but doe not wortk with 2.4 (latest). Are there plans to fix to work with 2.4, currently there are errors.

    Coding error detected, it must be fixed by a programmer: You must set the text for the node when you create it.

    yes sure there are... actually last evolution was asked y some customers for 1.9, but we are in migration pre-schedule for them, so it will be fixed in a little delay.....

    I'm adding two key features : authro defined parameters to enhance end user experience in querying himself part of data, and filter caching to improve really "read again" queries.

    Cheers
    Valery

    Anyone have success with this on Moodle/Oracle setup? I get it installed fine and then run into a whack of trouble.

    Hi Trevor,, i'mterribly sorry about that, but i have absoloutely no experimenting nor test facility (nor budget allocation wink ) to check and ensure Oracle compatibility. Dashboarding faces lot of performance issues that often needs using some optimized SQL tricks that may affect portability. May you possibly address me some typical issue reports i can check some unportable writings could be avoided.

    Also dashboard is being revised as oportunistic quick drawn design is reaching its limits. So some new version may arrive soon...

    Excuse me, my moodle is 2.4.1, currently there are errors.

    Coding error detected, it must be fixed by a programmer: You must set the text for the node when you create it.

    By the way, how can I input the data to database?

    thank for you
