<h2 class="first">Styling the Chart</h2>
<p>To change the visual appearance of a <a href="http://developer.yahoo.com/yui/charts/">Charts Control</a> instance, one uses the <code>style</code> initialization attribute. Each part of the chart, including the background and border, xAxis and yAxis, and the dataTip may be customized.</p>
<textarea name="code" class="JScript" rows="10" cols="60">
style:
{
border: {color: 0x96acb4, size: 12},
font: {name: "Arial Black", size: 14, color: 0x586b71},
dataTip:
{
border: {color: 0x2e434d, size: 2},
font: {name: "Arial Black", size: 13, color: 0x586b71}
},
xAxis:
{
color: 0x2e434d
},
yAxis:
{
color: 0x2e434d,
majorTicks: {color: 0x2e434d, length: 4},
minorTicks: {color: 0x2e434d, length: 2},
majorGridLines: {size: 0}
}
}
</textarea>
<p>Notice that the main <code>font</code> style applies to both of the axes on the chart. The dataTip includes a custom <code>border</code> and <code>font</code>. The yAxis includes custom ticks and we hide the majorGridLines by setting the <code>size</code> value to <code>0</code>.</p>
<h2>Setting Series Skins</h2>
<p>The series definition includes <code>style</code> values for both series with declarations for background images abd colors and the size of each marker.</p>
<textarea name="code" class="JScript" rows="10" cols="60">
var seriesDef =
[
{
yField: "pork",
displayName: "Sales of Pork",
style:
{
image: "assets/tube.png",
mode: "no-repeat",
color: 0x2e434d,
size: 40
}
},
{
yField: "beef",
displayName: "Sales of Beef",
style:
{
image: "assets/tube.png",
mode: "no-repeat",
color: 0xc2d81e,
size: 40
}
}
];
</textarea>
<p>The <code>mode</code> value specifies how the image will be displayed. In this case <code>"no-repeat"</code> ensures that the image will be displayed only once. Other possible values include <code>"repeat"</code>, <code>"repeat-x"</code>, <code>"repeat-y"</code>, and <code>"stretch"</code>. </div>
