Hi,
This is the code I am using.
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawVisualization);
var callCount = "<?= $chartCount?>";
var callDate = "<?= $chartDate?>";
var callCountPre = "<?= $chartCountPre?>";
var newCount = callCount.split("-");
var newDate = callDate.split("-");
for (var i = 0; i<7;i++) {
if (!newCount[i])
newCount[i] = 0;
eval("callCounts" + i + " = newCount[i]");
eval("callDates" + i + " = newDate[i]");
}
var newCountPre = callCountPre.split("-");
for (var i = 0; i<7;i++) {
if (!newCountPre[i])
newCountPre[i] = 0;
eval("callCountsPre" + i + " = newCountPre[i]");
}
function drawVisualization() {
var data = new google.visualization.DataTable();
data.addColumn('string', 'Range');
data.addColumn('number', '<?= $selectedRange?>');
data.addColumn('number', '<?= $selectedRangePre?>');
data.addRow([callDates0, parseInt(callCounts0),
parseInt(callCountsPre0)]);
data.addRow([callDates1, parseInt(callCounts1),
parseInt(callCountsPre1)]);
data.addRow([callDates2, parseInt(callCounts2),
parseInt(callCountsPre2)]);
data.addRow([callDates3, parseInt(callCounts3),
parseInt(callCountsPre3)]);
data.addRow([callDates4, parseInt(callCounts4),
parseInt(callCountsPre4)]);
data.addRow([callDates5, parseInt(callCounts5),
parseInt(callCountsPre5)]);
data.addRow([callDates6, parseInt(callCounts6),
parseInt(callCountsPre6)]);
// Create and draw the visualization.
new
google.visualization.LineChart(document.getElementById('visualization')).
draw(data, {curveType: "function",
width: 500, height: 200,
colors:['#1770CB','#F4C741'],
vAxis: {maxValue: <?= $maxChartValue ?>}
});
}
</script>
<div id="visualization"></div>
