Original Source

The y1 attribute is used to specify the first y-coordinate for drawing an SVG element that requires more than one coordinate. Elements that only need one coordinate use the {{SVGAttr("y")}} attribute instead.

Elements

You can use this attribute with the SVG elements described in the sections below.

<line>

For {{SVGElement('line')}}, y1 defines the y coordinate of the starting point of the line.

<table class="properties"> <tbody> <tr> <th scope="row">Value</th> <td> <strong ><a href="/en-US/docs/Web/SVG/Guides/Content_type#length" >&#x3C;length></a ></strong > | <strong ><a href="/en-US/docs/Web/SVG/Guides/Content_type#percentage" >&#x3C;percentage></a ></strong > | <strong ><a href="/en-US/docs/Web/SVG/Guides/Content_type#number" >&#x3C;number></a ></strong > </td> </tr> <tr> <th scope="row">Default value</th> <td><code>0</code></td> </tr> <tr> <th scope="row">Animatable</th> <td>Yes</td> </tr> </tbody> </table>

{{EmbedLiveSample('line', '100%', 200)}}

<linearGradient>

For {{SVGElement('linearGradient')}}, y1 defines the y coordinate of the starting point of the gradient vector used to map the gradient stop values. The exact behavior of this attribute is influenced by the {{SVGAttr('gradientUnits')}} attributes

<table class="properties"> <tbody> <tr> <th scope="row">Value</th> <td> <strong ><a href="/en-US/docs/Web/SVG/Guides/Content_type#length" >&#x3C;length></a ></strong > </td> </tr> <tr> <th scope="row">Default value</th> <td><code>0%</code></td> </tr> <tr> <th scope="row">Animatable</th> <td>Yes</td> </tr> </tbody> </table>
