# chart.margin

The margin between the outer edge of the chart and the plot area. The numbers in the array designate top, right, bottom and left respectively. Use the options `marginTop`, `marginRight`, `marginBottom` and `marginLeft` for shorthand setting of one option.

By default there is no margin. The actual space is dynamically calculated from the offset of axis labels, axis title, title, subtitle and legend in addition to the `spacingTop`, `spacingRight`, `spacingBottom` and `spacingLeft` options.
