Hi, The Chart library features sounds promising. As for the data engine - one thing that I think is missing is the ability to use the visualization to drive the aggregation in the SQL. today, you first write the SQL, you execute it, *limited by the number of results sent to the client*, and then you use viz to understand the results. Alternatively, if through the visualization I can generate a better SQL which returns returns an aggregated data-set then I can analyze a bigger amount of data.
I hope I was clear enough in my explanation :-) Eran On Fri, Mar 20, 2015 at 8:21 AM, madhuka udantha <madhukaudan...@gmail.com> wrote: > Hi, > > Here is my proposing ideas. > According to COMDEV-119 jira.
