I'm using Google Charts' Annotation Chart to display data. Everything's working but it's not showing the volume section, as seen in this google finance chart that, I believe, uses the same chart.
Here's what I have so far, but I don't know how to include that section:
google.charts.load('current', {'packages':['annotationchart']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var data = new google.visualization.DataTable();
data.addColumn('date', 'Date');
data.addColumn('number', 'Col1');
data.addColumn('string', 'Col2');
data.addColumn('string', 'Col3');
data.addColumn('number', 'Col4');
data.addColumn('string', 'Col5');
data.addColumn('string', 'Col6');
data.addRows([
[new Date(2017, 2, 15), 85, 'More', 'Even More',
91, undefined, undefined],
[new Date(2017, 2, 16), 93, 'Sales', 'First encounter',
99, undefined, undefined],
[new Date(2017, 2, 17), 75, 'Sales', 'Reached milestone',
96, 'Att', 'Good'],
[new Date(2017, 2, 18), 60, 'Sales', 'Low',
80, 'HR', 'Absences'],
[new Date(2017, 2, 19), 95, 'Sales', 'Goals',
85, 'HR', 'Vacation'],
[new Date(2017, 2, 20), 40, 'Sales', 'Training',
67, 'HR', 'PTO']
]);
var chart = new google.visualization.AnnotationChart(document.getElementById('chart_div'));
var options = {
displayAnnotations: true
};
chart.draw(data, options);
} <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<div id='chart_div' style='width: 900px; height: 500px;'></div>This is what the google finance chart looks like, but I can't seem to include the volume section marked in red:
