Annotation With Symbols Inside Stacked Bar Charts Using Google Chart Api
I have a stacked bar chart where I need to annotate the bars with $ symbol as the profit and costs are currency. I am successful in annotating of the bars without currency symbol b
Solution 1:
use google's NumberFormat class
you can create a pattern, and format each data column.
var formatCurr = new google.visualization.NumberFormat({pattern: '$#,##0'});
formatCurr.format(data, 1);
formatCurr.format(data, 2);
see following working snippet...
<html><head><scripttype="text/javascript"src="https://www.gstatic.com/charts/loader.js"></script><scripttype="text/javascript">
google.charts.load("current", {
packages: ["corechart"]
});
google.charts.setOnLoadCallback(drawChart);
functiondrawChart() {
var bar_chart_data = [
["Material", "Cost", "Profit", { role: 'style' },{ role: 'style' }],
["A", 100, 25, 'color: #F9F528','color: #0ACB53'],
["B", 4.2, 1.764, 'color: #F9F528','color: #0ACB53'],
["C", 110, 46.199999999999996, 'color: #F9F528','color: #0ACB53'],
["D", 7.56, 3.1752, 'color: #F9F528','color: #0ACB53'],
["E", 4.24, 1.7808, 'color: #F9F528','color: #0ACB53'],
["F", 0.8, 0.336, 'color: #F9F528','color: #0ACB53'],
["G", 2, 0.84, 'color: #F9F528','color: #0ACB53'],
["H", 0.8, 0.336, 'color: #F9F528','color: #0ACB53'],
]
var data = google.visualization.arrayToDataTable(bar_chart_data);
var formatCurr = new google.visualization.NumberFormat({pattern: '$#,##0'});
formatCurr.format(data, 1);
formatCurr.format(data, 2);
var view = new google.visualization.DataView(data);
view.setColumns([0, 1, {
calc: "stringify",
sourceColumn: 1,
type: "string",
role: "annotation"
}, 3, // <-- include style column2, {
calc: "stringify",
sourceColumn: 2,
type: "string",
role: "annotation"
}, 4// <-- include style column
]);
var options = {
title: "Live individual material cost break-up (%)",
width: 600,
height: 400,
bar: {
groupWidth: "95%"
},
legend: {
position: "none"
},
isStacked: 'percent',
hAxis: {
title: 'Percentage',
textStyle: {
fontSize: 8,
fontName: 'Muli',
bold: false,
},
titleTextStyle: {
fontSize: 12,
fontName: 'Muli',
bold: true,
}
},
vAxis: {
title: 'Material',
textStyle: {
fontSize: 10,
bold: false
},
titleTextStyle: {
fontSize: 12,
bold: true
}
},
};
var chart = new google.visualization.BarChart(document.getElementById("material_bar_chart"));
chart.draw(view, options);
}
</script></head><body><divid="material_bar_chart"style="width: 900px; height: 500px;"></div></body></html>
