<td valign="top" class="text"><p>All the charts in FusionCharts support the attribute <span class="codeInline">decimalPrecision</span>. If not specified a chart automatically shows number up to 2 decimal places. This single attribute lets you control the decimal precision of all the numbers on the chart. Using this attribute, you can globally set the number of decimal places of ALL numbers of the chart. For e.g., if you have numbers on your chart as 12.432,13.4 and 13 and you set <span class="codeInline"><chart ... decimalPrecision='0' ></span>, the numbers would be converted to 12, 13 and 13 respectively.</p> </td>

<ul>
<li><span class="codeInline">numberPrefix="$"</span> : Using this attribute, you could add prefix to all the numbers visible on the graph. For example, to represent all dollars figure on the chart, you could specify this attribute to ' $' to show like $40000, $50000. </li>
<li><span class="codeInline">numberSuffix="p.a"</span> : Using this attribute, you could add suffix to all the numbers visible on the graph. For example, to represent all figure quantified as per annum on the chart, you could specify this attribute to ' /a' to show like 40000/a, 50000/a. </li>
</ul>
<p>If you intend to use special characters for <span class="codeInline">numberPrefix</span> or <span class="codeInline">numberSuffix</span>, you'll need to URL Encode them when using <span class="codeInline">dataXML</span> method. For example, if you wish to have <span class="codeInline">numberSuffix</span> as % (like 30%), you'll need to specify it as under:<br />
<span class="codeInline">numberSuffix='%25'</span></p>
<p>In dataURL method, you can <strong>directly</strong> specify the character. </p>
