#### 9.8.2 Comments and Endnotes

Comments can be set either to the left or the right side of the chart as dictated by the `side` attribute. This attribute can also take the value `end`, which will turn the comment to an endnote. In fact endnotes are comments with their `side` attribute set to `end`. So you can convert all your comments to endnotes by redefining the `side` attribute of the ‘`comment`’ style, as below. For ease of use the `comment.text` and the `comment.side` chart options can also be used to set comment properties51.

    defstyle note [text.size.normal=16, text.size.small=10];
    defstyle comment [side=end];
    comment.side=right;
    comment.text.italics=yes;

When the chart contains comments on the side a line is drawn separating the comments from the chart text. You can change the properties of this line via the ‘`comment.line.*`’ chart options. Only the width, color and type of the line can be changed (not its radius or corner). You can turn this line off by selecting the ‘`none`’ line type. Similar, the background of the comments can be set via the ‘`comment.fill.*`’ chart options. These options can also be made part of designs. Finally, the space available on the side for comments can be adjusted with the `hspace left|right comment` command, see Spacing.

These are equivalent to changing the ‘`comment`’ style. There is no such shortcut for endnotes, yet.
