Hi Rahul,
Try this once..
widget.on('render',function(w, e) {
e.prefixText = '';
e.suffixText = '';
e.selectedColor = '#86b817'; /*The color of the chosen title*/
e.fontColor = '#cccccc'; /*The color of the unchosen titles*/
e.elementWidth = '103%';
e.descColor = '#a5a5a5';
e.parentMarginLeft = '-15px';
e.height = 32; /* affects the tabber widget default high*/
});
widget.tabs = [
{
title: "Column Chart",
displayWidgetIds : ["55797a9459ef031011000032"],
hideWidgetIds : ["557d408a4630ccdc11000019"]
},
{
title: "Table",
displayWidgetIds : ["557d408a4630ccdc11000019"],
hideWidgetIds : ["55797a9459ef031011000032"]
}
];
