How to add a point inside the Google Charts Visualization: Area chart like
the red point in the picture shown above and can i put some label above or
beside the point?
Here is the code that outputs the chart above
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Output1');
data.addColumn('number', 'Height');
data.addColumn({type:'string', role:'annotation'});
data.addRows([
<?php echo"['', 2, null],"; ?>
<?php echo"['', 2, '1 Kpa ---------->'],"; ?>
<?php echo"['2', 1, '<---------- 2'],"; ?>
<?php echo"['3 σ', 0, '<---------- 3 σ']"; ?>
]);
var options = {
title: 'Total Stress',
hAxis: {title: '<-------- Direction', titleTextStyle: {color: '#333'}},
vAxis: { ticks: [{v:2, f:'1 Kpa ->'}, {v:1, f:'1 m'},{v:0, f:'length ^ 1
m'},{v:0, f:'1 m'}] }
};
var chart = new
google.visualization.AreaChart(document.getElementById('total_stress'));
chart.draw(data, options);
}
