dynamically change the Numberformat of the y-axis (Chart)

Hello, 
 
have anyone a idea how I can dynamically change the Numberformat of the y-axis in the Chart? Exactly I search a way to change the "Fraction Digits". 
 
For example in a table I scripting it: 
if (params["transaktion"].value.search("Fall")>0){ 
this.getStyle().numberFormat = "###,##0.0000";} 
else { 
this.getStyle().numberFormat = "###,##0.0";}
How can I do this in a chart??? <a class='bbc_url' href='http://www.birt-exchange.org/org/forum/public/style_emoticons/'>http://www.birt-exchange.org/org/forum/public/style_emoticons/</a><#EMO_DIR#>/confused.gif 
 
 
Thanks a lot for your help.

Hi,

Attached is an example that uses the beforeGeneration function of the chart's onRender event to dynamically change the format of the y-Axis. In the example, based on the country selected (USA or UK) for the query, the numbers will be prefixed with a '$' or a '?' sign.

The code for the onrender event looks like this:

importPackage( Packages.org.eclipse.birt.chart.model.attribute.impl );

function beforeGeneration( chart, icsc )
{
country = icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("g_country");
xAxis = chart.getBaseAxes()[0];
yAxis = chart.getOrthogonalAxes( xAxis, true)[0];
if (country == "USA")
yAxis.setFormatSpecifier( JavaNumberFormatSpecifierImpl.create("$#,##0.00") );
else
yAxis.setFormatSpecifier( JavaNumberFormatSpecifierImpl.create("?#,##0.00") );
}

Hope this helps!
