Hi,
this is my chart code.
<script type="text/javascript" src="https://www.google.com/jsapi";></script>
<script type="text/javascript">
google.load('visualization', '1', {packages: ['corechart']});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Data');
data.addColumn('number', 'P.L.');
<?php
$recupera_valori = $mysqli->query( "SELECT * FROM cronoprogramma
WHERE verificato=1 LIMIT 90");
while ( $row = mysqli_fetch_array($recupera_valori) )
{
$data = $row['data'];
$valore = $row['valore'];
echo("
data.addRows([
['$data', $valore]
])
");
}
?>
var options = {
pointSize: 5,
pointShape: 'circle',
backgroundColor: '#f8f8f8',
width: 1400,
height: 700,
hAxis: {
title: ''
},
vAxis: {
title: ''
},
};
var chart = new google.visualization.LineChart(document.getElementById
('ex0'));
chart.draw(data, options);
}
</script>
I want to date "2015-06-22" the point in the graph is a square.
