Display item in legend even if value = 0 with Google Charts Tools Pie Chart

I'm using Google Charts Tools, specifically the Pie Chart.

Naturally, if a item has a value of 0, it is not displayed in the pie (since it occupies 0% of the pie). However, it doesn't display in the legend either.

How can I manipulate the initialization options to still show a 0 value item in the legend, so that users can see that the item exists, it just has a 0 value?

setting sliceVisibilityThreshold as zero will solve your problem.

function drawVisualization() {

  // Create and populate the data table.

  var data = google.visualization.arrayToDataTable([

    ['Task', 'Hours per Day'],

    ['Work', 11],

    ['Eat', 0],

    ['Commute', 2],

    ['Watch TV', 2],

    ['Sleep', 7]

  ]);



  // Create and draw the visualization.

  new google.visualization.PieChart(document.getElementById('visualization')).

      draw(data, {title:So, how was your day?,

                 sliceVisibilityThreshold:0

                 });

}
