    copied!<p>I've created a chart as the code below, and a also have a checkbox with a handler function that I want to show or hide the chart labels depending on its status. My question is, how do I make the labels hidden without also hiding the actual chart values?</p> <pre><code>// checkbox handler code handler: function() { if(Ext.getCmp('chk_showLabels').getValue()) { // function to show labels here } else { // function to hide labels here } } // Chart code { xtype : 'chart', animate : true, id : 'chart', width : 996, height : 432, shadow : false, store : volumes, theme : 'Category1', axes : [{ type : 'Numeric', position : 'right', fields : ['participacao'], title : 'Percentual', label : { renderer : Ext.util.Format.numberRenderer('0.00%') } }, { type : 'Numeric', position : 'left', grid : true, fields : ['volume'], title : 'Volume', label : { renderer : Ext.util.Format.numberRenderer('0./i') } }, { type : 'Category', position : 'bottom', fields : ['data'], label : { rotate : { degrees : 270 } } } ], series : [{ type : 'column', axis : 'right', xField : 'data', yField : ['participacao'] }, { type : 'line', axis : 'right', xField : 'data', yField : ['participacao'], smooth : true, fill : true, style : { opacity : .1 }, label : { renderer : Ext.util.Format.numberRenderer('0./i') }, markerConfig : { type : 'circle', size : 5 }, tips : { trackMouse : true, width : 148, height : 36, renderer : function (storeItem, item) { this.setTitle('Participação: ' + Ext.util.Format.number(storeItem.get('participacao'), "0.00") + '% \n Volume: ' + storeItem.get('volume')); } } } ] } </code></pre> <p>Thanks a lot</p>
