  y: [4.3, 8.2, 4.1, 5.6, -3, -0.2, 0.3, 0.4, 4.1, 5, 4.6, -0.2, -8.5, -9.1, -2.7, -2.7, -17, -11.3, -5.5, -6.5, -16.9, -12, -6.1, -6.6, -7.9, -10.8, -14.8, -11, -4.4, -1.3, -1.1],
  mode: 'lines',
  type: 'scatter',

var data = [ trace1 ];

var layout = {
  xaxis: {
    type: 'date',
    title: 'January Weather'
