javascript - Remove padding or margins from Google Charts

Question

// Load the Visualization API and the piechart package.
google.load('visualization', '1.0', {'packages':['corechart']});

// Set a callback to run when the Google Visualization API is loaded.
google.setOnLoadCallback(drawChart);

// Callback that creates and populates a data table,
// instantiates the pie chart, passes in the data and
// draws it.
function drawChart() {

  // Create the data table.
  var data = new google.visualization.DataTable();
  data.addColumn('string', 'Topping');
  data.addColumn('number', 'Slices');

  var myData = {
    'Mushrooms': 3,
    'Onions': 1,
    'Olives': 1,
    'Zucchini': 1,
    'Pepperoni': 2
  };

  var rows = [];
  for (element in myData) {
      rows.push([element + " (" + myData[element] + ")", myData[element]])
  }
  data.addRows(rows);

  // Set chart options
  var options = {'title':'How Much Pizza I Ate Last Night',
                 'width':450,
                 'height':300};

  // Instantiate and draw our chart, passing in some options.
  var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
  chart.draw(data, options);
}

By adding and tuning some configuration options listed in the API documentation, you can create a lot of different styles. For instance, here is a version that removes most of the extra blank space by setting the chartArea.width to 100% and chartArea.height to 80% and moving the legend.position to bottom:

// Set chart options
var options = {'title': 'How Much Pizza I Ate Last Night',
               'width': 350,
               'height': 400,
               'chartArea': {'width': '100%', 'height': '80%'},
               'legend': {'position': 'bottom'}
    };

If you want to tune it more, try changing these values or using other properties from the link above.
