16 | <p>Flot has support for simple background decorations such as
|
||
17 | lines and rectangles. They can be useful for marking up certain |
||
18 | areas. You can easily add any HTML you need with standard DOM |
||
19 | manipulation, e.g. for labels. For drawing custom shapes there is |
||
20 | also direct access to the canvas.</p>
