FusionCharts lets you define various paddings and margins. We will see them one-by-one.
 
Chart Margins
By default, FusionCharts provides some padding between the chart border and the canvas. This is called the chart margin and each of the margins - left, right, top, bottom chart can be set individually.

Chart Left Margin

Amount of empty space that you want to put on the left side of your chart is called chart left margin. Nothing is rendered in this space. The XML used to configure the same is:
<chart chartLeftMargin="15">
 

Chart Right Margin

Amount of empty space that you want to put on the right side of your chart.

<chart chartRightMargin="15">
 

Chart Top Margin

Amount of empty space that you want to put on the top of your chart.

<chart chartTopMargin="10">
 

Chart Bottom Margin

Amount of empty space that you want to put on the bottom of your chart.

< chart chartBottomMargin="10">
 
Caption Padding

This attribute lets you define the space between the caption of the chart and the top of the chart canvas. But when you have a sub-caption defined in the chart, it controls the space between the sub-caption and the top of the chart canvas.

x-Axis Name Padding

Using this, you can set the distance between the top of x-axis title and the bottom of data labels (or canvas, if data labels are not shown).

For a line/area chart, the padding between the canvas border and the position where the line/area chart begins to draw is called canvas padding.
