Hi, Here is my proposing ideas. According to COMDEV-119 jira. Charts are hard coded until now and data transformation issue was highlighted since different charts have different pivot fields eg: Area charts, Scatter, Surface charts, Bubble charts, Radar charts. etc..
To solve this I am introducing a two major component one is called 'Chart library' and 'Data transformation engine'. Chart library is located where it shows the chats that are currently plugged. There we can plug chart types and those can be reused. *Chart library features * - Users can select the chart from library - Those charts are pluggable to library - Charts can be plugged by config(json)/UI with wizard - Configuration/Meta file of the chart contains interface, libs, themes and a data transformation types/mappings *Data Transformation Engine* 'Data transformation engine' contains data transformation modules. Those modules are also pluggable to engine. Those have connections to charts. Data transformation engine sit between the data (sql) and chart. So this module converts data and map them to each chart pivot field - This module will look at pivot fields of the chart - Selected attributes of the SQL query - Attribute value operations improvement (string split, value aggregation, round number round) Another improvement that I notice is that - Query Edit auto-completion support (with Ctrl+space) Your ideas are welcome here Thanks On Fri, Mar 20, 2015 at 10:57 AM, madhuka udantha <madhukaudan...@gmail.com> wrote: > Hi All, > > I'm Udantha, MSc.
