Hi All, Today I had a progress update of igviz.js with Srinath .He pointed out several improvements for the project.
- Add graph sketching support to igviz.js - Come up with a tabular representation for a graph - Improve the styles in samples site - Add single number diagram ( min/max/average.. with a distribution curve or histogram) - Add more aggregate function (min,max,avg..) support to dirll-down feature Currently this library supports following visualizations and features.Please find the source code of igviz.js [2] <https://github.com/dunithd/igviz> and the samples site [1] <http://dunithd.github.io/igviz/samples/> , Any thoughts/suggestions are highly appreciated *Charts ( All of these charts are implemented in Vega.js)* 1. Bar Charts 1. Two dimensional Bar chart 2. Grouped Bar chart 3. Stacked Bar chart 2. Line Charts 1. Single Series Line chart 2. Multi series line chart 3. Area Charts 1. Single series area chart 2. Multi series area chart 3. Stacked area chart 4. Scatter Plot 1. Four Dimensional charts (x,y,point color,point size) *Other Types of Visualizations ( Implemented in D3.js)* - Map - Arc (Progress representation) - Table Representation of a data table (Conditional formating based on dataset) *Features of Charts* - Legends (B2,B3,L2,A2,A3) - Tool-tips (L1,L2,A1,A2, S1) - Drill Downing (B1) - Grids (users can configure as they want) - Real Time updates (B1,A1,A2,L1) - Responsive Handlers And Dynamic Resizing *Basic API* chart = igviz.setup("#divID",chartConfig,dataTable.metadata) //chartConfig-minimal set of parameters chart.setXaxis(axisConfig) .setYaxis(yaxisConfig) .setDimension(dimensionConfig) //optional visual customization chart.plot( dataTable.data, callBack); //draw the charts based on the parameters chart.update(newData) //real-time updating chart.resize() //Responsive Handler [1] http://dunithd.github.io/igviz/samples/ [2] https://github.com/dunithd/igviz [3] Generic UI Parameter Names <https://docs.google.com/a/wso2.com/spreadsheets/d/1tCf3lTZ7kkEXdK7T75tKEXqm0QhsZZpiF47saKNMboc/edit#gid=0> Thanks, On Tue, Mar 3, 2015 at 6:02 AM, Tharindu Munasinghe <tharin...@wso2.com> wrote: > +1 , I will do a bar chart sample using 'Vega' with the features we have > discussed and then we will see how we can extend that implementation to the > other types of charts :) > > On Mon, Mar 2, 2015 at 6:05 PM, Dunith Dhanushka <dun...@wso2.com> wrote: > >> >> Hi all, >> >> Today we had a discussion on using Vega [1] library underneath igviz. >> Vega comes with a highlevel visualization grammer that runs on top of D3. >> In addition to that it's got some polished UI so that it'll save more >> efforts for fine tuning the charts. >> >> Please refer mail thread [RFC: Building a Generic Configurable UI Gadget >> for Analytics] for a background on IGviz. >> >> Igviz's main API interface is >> >> var chart = igviz.plot(canvas,chartConfig,dataTable); >> >> Plan is to keep Igviz's plot() method unchanged and transform DataTable >> and chartConfig objects to the format that vega expects. >> >> where canvas is the div element that chart is being drawn, >> chartConfig is the JSON object that contain parameters required to draw >> the chart.
