	padding: {left: 30, right: 0, top: 10, bottom: 30},

	// Background color to render.

	// Use the predefined blue colorscheme.
	colorScheme: 'blue',

	// Set the labels.
   	xTicks: [
		{v:0, label:'January'},

// Instantiate a new PieCart.
var pie = new Plotr.PieChart('pie1',options);
// Add a dataset to it.
pie.addDataset(dataset);
// Render it.
pie.render();

PieChart (pieRadius = 0.2)

// Change some attributes.
Object.extend(options,{
	// Use the predefined grey colorscheme.
	colorScheme: 'grey',

	pieRadius: '0.2',

	// Background color to render.
	backgroundColor: '#d8efb0'
});

// Instead of instantiating a new PieChart object,
// you also can use reset(), that resets the options and datasets.
pie.reset();
pie.addDataset(dataset);
// Render the PieChart.
pie.render('pie2', options);
