Combining chart types

To combine several chart types in one chart you only need to create series of different types:

series: [{
    type: 'column',
    name: 'Jane',
    data: [3, 2, 1, 3, 4]
}, {
    type: 'column',
    name: 'John',
    data: [2, 3, 5, 7, 6]
}, {
    type: 'column',
    name: 'Joe',
    data: [4, 3, 3, 9, 0]
}, {
    type: 'spline',
    name: 'Average',
    data: [3, 2.67, 3, 6.33, 3.33]
}]
