Answer 1

it was very simple thing need to change for displaying the results,i used ColumnChart in place of Barchart at that time my problem is solved.
my code after changing is
<script type="text/javascript">
google.charts.setOnLoadCallback(drawChart);
imagepath_comparison="";
function drawChart() {
var data = google.visualization.arrayToDataTable([<?=$data;?>]);
var options = {
title: 'GRAPH ANALYSIS',
vAxis: {title: "SUBJECTS"},
hAxis: {
title: "MARKS"
}
};
var chart3 = new google.visualization.BarChart (document.getElementById("columnchart_material"));
google.visualization.events.addListener(chart3, 'ready', function () {
imagepath_comparison=chart3.getImageURI();
drawChart1();
});
chart3.draw(data, options);
}
</script>
