You may define labels for objects which will be represent on the chart. Line, bar and area charts show labels above elements, pie charts – outside sectors.
Labels are defined by templates:
var chart = new dhx.ui({ view:"chart", ... label:"#sales#" ... })
Pie chart allows to define labels inside its sectors as well - pieInnerText parameter:
var chart = new dhx.ui({ view:"chart", ... label:"#year#", pieInnerText:function(obj){ var sum = chart.sum("#sales#"); return Math.round(obj.sales/sum*100) +"%" } ... });
