How can I get a data point value from the chart series?
You can get the information related to a point in series when you move mouse over the point or by clicking the point using OnClientPointRegionMouseMove or OnClientPointRegionClick event.
Point region mouse move
OnClientPointRegionMouseMove event is triggered when moving mouse over a point.
Point region click
OnClientPointRegionClick event is triggered on clicking a point.
ASP
<ej:Chart ID="container" OnClientPointRegionClick="mousemove" OnClientPointRegionMouseMove="mousemove" runat="server">
</ej:Chart>
<script type="text/javascript">
//Event handler for mouse move and mouse click events
function mousemove(sender) {
series = sender.model.series[sender.data.region.SeriesIndex];
var X = series.points[sender.data.region.Region.PointIndex].x;
var Y = series.points[sender.data.region.Region.PointIndex].y;
alert("X:" + X + " Y:" + Y);
}
</script>
