+<p>The <code><strong>CanvasRenderingContext2D</strong></code><strong><code>.setLineDash()</code></strong> method of the Canvas 2D API sets the line dash pattern.</p>

+<dl>
+ <dt><code>segments</code></dt>
+ <dd>An {{jsxref("Array")}}. A list of numbers that specifies distances to alternately draw a line and a gap (in coordinate space units). If the number of elements in the array is odd, the elements of the array get copied and concatenated. For example, <code>[5, 15, 25]</code> will become <code>[5, 15, 25, 5, 15, 25]</code>. An empty array clears the dashes, so that a solid line will be drawn.</dd>
