Thank you for prompt reply, that's perfectly worked for me.

How can I access a sample data (under data node) in a script tag on report template to build the chart axis and data.
In the below example I want to read the data form sample data.

<script>
$(function () {

var d1 = [];
for (var i = 0; i < 14; i += 0.5) {
d1.push([i, Math.sin(i)]);
}

$.plot("#placeholder", [d1]);
});
</script>
