This was trying to render an area chart. dataitem.value = 38.

chartEntry.push({ time: timestamp, y: dataItem.value });

$scope.areaAxes = ['left', 'right', 'bottom'];

Can you show me how you define chartEntry?

var timestamp = ((new Date()).getTime() / 1000) | 0; var chartEntry = []; chartEntry.push({ time: 0, y: 0 });
