If you set the is3D
option to true
, your pie chart will be drawn as though it has three dimensions:
is3D
is false
by default, so here we explicitly set it to true
:
<html> <head> <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script> <script type="text/javascript"> google.charts.load("current", {packages:["corechart"]}); google.charts.setOnLoadCallback(drawChart); function drawChart() { var data = google.visualization.arrayToDataTable([ ['Task', 'Hours per Day'], ['Work', 11], ['Eat', 2], ['Commute', 2], ['Watch TV', 2], ['Sleep', 7] ]); var options = { title: 'My Daily Activities', is3D: true, }; var chart = new google.visualization.PieChart(document.getElementById('piechart_3d')); chart.draw(data, options); } </script> </head> <body> <div id="piechart_3d" style="width: 900px; height: 500px;"></div> </body> </html>Making a Donut Chart
A donut chart is a pie chart with a hole in the center. You can create donut charts with the pieHole
option:
The pieHole
option should be set to a number between 0 and 1, corresponding to the ratio of radii between the hole and the chart. Numbers between 0.4 and 0.6 will look best on most charts. Values equal to or greater than 1 will be ignored, and a value of 0 will completely shut your piehole.
<html> <head> <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script> <script type="text/javascript"> google.charts.load("current", {packages:["corechart"]}); google.charts.setOnLoadCallback(drawChart); function drawChart() { var data = google.visualization.arrayToDataTable([ ['Task', 'Hours per Day'], ['Work', 11], ['Eat', 2], ['Commute', 2], ['Watch TV', 2], ['Sleep', 7] ]); var options = { title: 'My Daily Activities', pieHole: 0.4, }; var chart = new google.visualization.PieChart(document.getElementById('donutchart')); chart.draw(data, options); } </script> </head> <body> <div id="donutchart" style="width: 900px; height: 500px;"></div> </body> </html>
You can't combine the pieHole
and is3D
options; if you do, pieHole
will be ignored.
Note that Google Charts tries to place the label as close to the center of the slice as possible. If you have a donut chart with just one slice, the center of the slice may fall into the donut hole. In that case, change the color of the label:
Optionsvar options = { pieHole: 0.5, pieSliceTextStyle: { color: 'black', }, legend: 'none' };Full HTML
<html> <head> <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script> <script type="text/javascript"> google.charts.load('current', {'packages':['corechart']}); google.charts.setOnLoadCallback(drawChart); function drawChart() { var data = google.visualization.arrayToDataTable([ ['Effort', 'Amount given'], ['My all', 100], ]); var options = { pieHole: 0.5, pieSliceTextStyle: { color: 'black', }, legend: 'none' }; var chart = new google.visualization.PieChart(document.getElementById('donut_single')); chart.draw(data, options); } </script> </head> <body> <div id="donut_single" style="width: 900px; height: 500px;"></div> </body> </html>Rotating a Pie Chart
By default, pie charts begin with the left edge of the first slice pointing straight up. You can change that with the pieStartAngle
option:
Here, we rotate the chart clockwise 100 degrees with an option of pieStartAngle: 100
. (So chosen because that particular angle happens to make the "Italian" label fit inside the slice.)
<html> <head> <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script> <script type="text/javascript"> google.charts.load("current", {packages:["corechart"]}); google.charts.setOnLoadCallback(drawChart); function drawChart() { var data = google.visualization.arrayToDataTable([ ['Language', 'Speakers (in millions)'], ['German', 5.85], ['French', 1.66], ['Italian', 0.316], ['Romansh', 0.0791] ]); var options = { legend: 'none', pieSliceText: 'label', title: 'Swiss Language Use (100 degree rotation)', pieStartAngle: 100, }; var chart = new google.visualization.PieChart(document.getElementById('piechart')); chart.draw(data, options); } </script> </head> <body> <div id="piechart" style="width: 900px; height: 500px;"></div> </body> </html>Exploding a Slice
You can separate pie slices from the rest of the chart with the offset
property of the slices
option:
To separate a slice, create a slices
object and assign the appropriate slice number an offset
between 0 and 1. Below, we assign progressively larger offsets to slices 4 (Gujarati), 12 (Marathi), 14 (Oriya), and 15 (Punjabi):
<html> <head> <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script> <script type="text/javascript"> google.charts.load("current", {packages:["corechart"]}); google.charts.setOnLoadCallback(drawChart); function drawChart() { var data = google.visualization.arrayToDataTable([ ['Language', 'Speakers (in millions)'], ['Assamese', 13], ['Bengali', 83], ['Bodo', 1.4], ['Dogri', 2.3], ['Gujarati', 46], ['Hindi', 300], ['Kannada', 38], ['Kashmiri', 5.5], ['Konkani', 5], ['Maithili', 20], ['Malayalam', 33], ['Manipuri', 1.5], ['Marathi', 72], ['Nepali', 2.9], ['Oriya', 33], ['Punjabi', 29], ['Sanskrit', 0.01], ['Santhali', 6.5], ['Sindhi', 2.5], ['Tamil', 61], ['Telugu', 74], ['Urdu', 52] ]); var options = { title: 'Indian Language Use', legend: 'none', pieSliceText: 'label', slices: { 4: {offset: 0.2}, 12: {offset: 0.3}, 14: {offset: 0.4}, 15: {offset: 0.5}, }, }; var chart = new google.visualization.PieChart(document.getElementById('piechart')); chart.draw(data, options); } </script> </head> <body> <div id="piechart" style="width: 900px; height: 500px;"></div> </body> </html>Removing Slices
To omit a slice, change the color to 'transparent'
:
We also used the pieStartAngle
to rotate the chart 135 degrees, pieSliceText
to remove the text from the slices, and tooltip.trigger
to disable tooltips:
<html> <head> <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script> <script type="text/javascript"> google.charts.load("current", {packages:["corechart"]}); google.charts.setOnLoadCallback(drawChart); function drawChart() { var data = google.visualization.arrayToDataTable([ ['Pac Man', 'Percentage'], ['', 75], ['', 25] ]); var options = { legend: 'none', pieSliceText: 'none', pieStartAngle: 135, tooltip: { trigger: 'none' }, slices: { 0: { color: 'yellow' }, 1: { color: 'transparent' } } }; var chart = new google.visualization.PieChart(document.getElementById('pacman')); chart.draw(data, options); } </script> </head> <body> <div id="pacman" style="width: 900px; height: 500px;"></div> </body> </html>Slice Visibility Threshold
You can set a value as the threshold for a pie slice to render individually. This value corresponds to a fraction of the chart (with the whole chart being of value 1). To set this threshold as a percentage of the whole, divide the percentage desired by 100 (for a 20% threshold, the value would be 0.2).
sliceVisibilityThreshold: 5/8 // This is equivalent to 0.625 or 62.5% of the chart.
Any slices smaller than this threshold will be combined into a single "Other" slice, and will have the combined value of all slices below the threshold.
google.charts.load('current', {'packages':['corechart']}); google.charts.setOnLoadCallback(drawChart); function drawChart() { var data = new google.visualization.DataTable(); data.addColumn('string', 'Pizza'); data.addColumn('number', 'Populartiy'); data.addRows([ ['Pepperoni', 33], ['Hawaiian', 26], ['Mushroom', 22], ['Sausage', 10], // Below limit. ['Anchovies', 9] // Below limit. ]); var options = { title: 'Popularity of Types of Pizza', sliceVisibilityThreshold: .2 }; var chart = new google.visualization.PieChart(document.getElementById('chart_div')); chart.draw(data, options); }Loading

slicesAn array of objects, each describing the format of the corresponding slice in the pie. To use default values for a slice, specify an empty object (i.e., {}
). If a slice or a value is not specified, the global value will be used. Each object supports the following properties:
color
- The color to use for this slice. Specify a valid HTML color string.offset
- How far to separate the slice from the rest of the pie, from 0.0 (not at all) to 1.0 (the pie's radius).textStyle
- Overrides the global pieSliceTextStyle
for this slice.You can specify either an array of objects, each of which applies to the slice in the order given, or you can specify an object where each child has a numeric key indicating which slice it applies to. For example, the following two declarations are identical, and declare the first slice as black and the fourth as red:
