Uncaught TypeError: Cannot read property 'ui5' of undefined

1370 Views

Hi,

I'm trying to read the JSON data returned from HTTP GET of a url and using this data to populate my Line chart. But its throwing error 'Uncaught TypeError: Cannot read property 'ui5' of undefined' in the line containing 'new sap.viz.ui5.data.FlattenedDataset'. I dont know whats the mistake.

My code:

var oModel = new sap.ui.model.json.JSONModel();

oModel.loadData(url);

sap.ui.getCore().setModel(oModel);

var dataset = new sap.viz.ui5.data.FlattenedDataset({

dimensions : [

{

axis : 1,

name : 'Timestamp',

value : "{timestamp}"

}

],

measures : [

{

group : 1,

name : 'Power (in KW.h)',

value : '{power}'

},

{

group: 2,

name : 'No of Plugs',

value : '{numberOfPlugs}'

}

],

data : {

path : "/_embedded/overallPowers"

}

});

var line = new sap.viz.ui5.DualLine({

id : "dualline",

width : "100%",

height : "400px",

title : {

visible : true,

text : 'Power Utilisation'

},

xAxis : {

title : {

visible : true

}

},

yAxis : {

title : {

visible : true

}

},

dataset : dataset

});

line.setModel(oModel);

line.placeAt("content");

</script>

</head>

<body id="content" class="sapUiBody">

</body>

</html>

input JSON data which is returned from url:

{

"overallPowers" : [ {
