How to Show Percentage and Values together in Google Pie Charts

← PrevNext →

I have previously submitted a post on how to create Google Pie chart with data extracted from an SQL Server database using Web API. I have received many queries from my readers asking me how to show the percentage and values together on Google Pie charts. Here it is.

Show Value and Percentage in Google Pie Charts

In my previous article, I have used the pieHole option to create a Donut chart. Its just a pie chart with a hole in the center. The default text that is displayed on the chart is percentage. Look at the figure below.

Creating a Donut Chart using Google Charts API

However, to show the value along with percentage on the Pie chart, you can use an option called pieSliceText and set the value as value-and-percentage. This is a combination of two values. See here.

The Markup
<!DOCTYPE html>
    <script type="text/javascript" src=""></script>
    <div id="chart" style="width:900px; height:500px;"></div> 
The Script
    google.charts.load("visualization", "1", { packages: ["corechart"] });

    function DrawPieChart() {
        var arrSales =
            ['Month', 'Sales Figure'],
            ['JAN', 21],
            ['FEB', 56],
            ['MAR', 14],
            ['APR', 61],
            ['MAY', 45]

        var options = {
            title: 'Monthly Sales',
            is3D: true,
            pieSliceText: 'value-and-percentage'

        var figures = google.visualization.arrayToDataTable(arrSales);

        var chart = new google.visualization.PieChart(document.getElementById('chart'));

        // DRAW THE CHART.
        chart.draw(figures, options);
See this demo

See the options variable in the script and see how I have used pieSliceText option. I have an array of data, for month and “sales figures” (in numbers). When you load the page without using the pieSliceText option, it will show the percentage (of total values) on each slice. This is its default behavior.

Note: If you are using dynamic data for your Google charts, you’ll have to define this option.

Now, create interactive and animated Graphs (charts) using Google Chart API.

Configuration Option pieSliceText

The configuration option pieSliceText is used to define the content of the text displayed on the slice. You can define it using four values.

‘percentage’: Shows the percentage of the slice size. For example,

var options = {
    pieSliceText: 'percentage'

‘value’: Shows values in each slice. For example, pieSliceText: 'value'

‘label’: The name of each slice. The name of label is also shown at right side of the chart. See the first image above.

var options = {
    pieSliceText: 'label'

‘none’: Use this option to hide texts on the slices. Show nothing if you wish.

‘value-and-percentage’: Finally, you can use this option to show both percentage and value on each slice. Like I have used in my example above.

var options = {
    pieSliceText: 'value-and-percentage'

Well, that’s it. Thanks for reading.
