#FENIX UI CHART

Requirejs import :

define(['fx-chart/start'], function (ChartCreator) {
...

From a Fenix ressource (FX in this document) and some parameters provided to the initialization function, a pivotator-based creator will perform three mains operations : -denormalisation of the dataset(optional) -aggregation (optional) -renderisation of the result with an external library

Constructor :

   this.chart = new ChartCreator(config);

with config is a json Object with these fields :

Parameter Type Default Value Example Description
type string - type:"column" type of chart we want to display currently available : "line","column", "column_stacked", "area", "pyramide", "area_stacked", "scatter","boxplot"
x json array [] x:["Country_EN","Indicator_EN"] List the dimensions to put in x-axis of the graph
series json array [] series:["Year"] List the dimensions that will be inerpreted as series in the graph
aggregations json array [] aggregations:["ElementCode_EN"] FX columns we want to aggregate,they will not appears in the Grid
y json array [] y:["values"] describe wich FX columns will be aggregates and displayed as Y-axis of the chart
aggregationFn json Object {} {value:"sum",Flag:"dif",Units:"dif"} This object is needed to identify which aggregation function have to be applied for each field on the "values" part of the dataset. The functions identifiers "sum" and dif in this example refer to a function of aggregation implemented in the functions part of the application and can be easily extended if needed
formatter string - "localstring" or "value" identifier of the formater function for the value field localstring result will be in this format : "1 250,12", value will return 1250,12 ; value is recommanded for charting
hidden json array
hidden:["DomainCode"] this FX columns will not appear in the name of the series or of the X-axis
decimals integer decimals:2 number of decimals in the values numbers
el CSS3 Selector/JavaScript DOM element/jQuery DOM element - "#container" Optional component container. if specified items's will be searched within it otherwise within the whole document.
model


The ressource FENIX to display
Full example : ```javascript var FX={ metadata:{ dsd:{ columns:[ {"id" : "country","title" : {"EN" : "COUNTRY CODE"},key:true}, {"id" : "country_EN","title" : {"EN" : "COUNTRIES"}}, {"id" : "element","title" : { "EN" : "elementcode"},key:true}, {"id" : "element_EN","title" : {"EN" : "element"}}, {"id" : "item","title" : {"EN" : "Item"},key:true}, {"id" : "item_EN","title" : {"EN" : "item"}}, {"id" : "year","title" : {"EN" : "year"},key:true,subject:"time"}, {"id" : "um","title" : {"EN" : "um"},subject:"um"}, {"id" : "value","title" : {"EN" : "value"},subject:"value",dataType:"number"}, {"id" : "flag","title" : {"EN" : "flag"},subject:"flag"}, {"id" : "v1","title" : {"EN" : "v1"},dataType:"number",subject:"value"}, {"id" : "v1|*v2","title" : {"EN" : "v2"},subject:"flag"} ,{"id" : "v3","title" : {"EN" : "v3"}},{"id" : "v4","title" : {"EN" : "v4"}},{"id" : "v5","title" : {"EN" : "v5"}} ] } },

"data" : [ ["4","Algeria","5312","Area_harvested","366","Artichokes","2006","Ha","1713.00","","","003","1","007",""], ["4","Algeria","5312","Area_harvested","366","Artichokes","2007","Ha","1813.00","","","003","1","007",""]]};

var config={ series :["country_EN","element_EN","item_EN"], x :["year"], aggregations:["item_EN"], y:["value"], aggregationFn:{value:"sum"}, formatter:"localstring", model:FX, el:"#result", type:"line" }

this.chart = new ChartCreator(config);

will create a line chart in the container with the ID=result with country label, element label in row and the year in columns, group by the item: the aggregation function used will be the sum for the columns "value"


#update
the update function allow the user to modify the config file and refresh the chart : model,el have don't need to be provided.
example : 
```javascript
this.chart.update({type:"area"})
