Donut charts documentation

Donut charts were formerly separate charts, however it's now simply a variant of the Pie chart.

Example

<script>
    window.onload = function ()
    {
        // The data to be shown on the Donut chart
        var data = [45,57,48,32];
    
        // Create the Donut chart (which is really a Pie chart).
        var donut = new OfficeExcel.Pie('myDonut', data);
        
        // Configure the Donut chart to look as wanted.
        donut.Set('chart.labels', ['Jan', 'Ben', 'Mark', 'Lucy']);
        donut.Set('chart.linewidth', 5);
        donut.Set('chart.strokestyle', 'white');
        donut.Set('chart.tooltips', ['Jan', 'Ben', 'Mark', 'Lucy']);
        
        // Specify the variant, which turns the Pie chart into a Donut chart.
        donut.Set('chart.variant', 'donut');
        
        // Call the .Draw() method to draw the Donut chart
        donut.Draw();
    }
</script>
