dynamic size of labels in Y-Axis

hi i have a problem with the Y-axis

i want to modify the labels on the Y-Axis with a dynamic suffix e.g

5,20 MWh
13,20 KWh
1,20 KWh
500,00 Wh

etc

i tried with:

function Wh(val)
{
if(val<1000)
return format("# Wh",val);
else if(val<1000000)
return format("#,## KWh",val/10);
else if(val <1000000000)
return format("#,## MWh",val/10000);
return format("#,## GWh",val/10000000);
}

function beforeDrawAxisLabel( axis, label, icsc )
{
if(axis.getTitle().getCaption().getValue() == "Y")
label.getCaption().setValue(Wh(label.getCaption().getValue()));
}

i works but only if i set a fixed label span with 60 points

but i want to set the span dynamic without fixed!

if i uncheck it some labels are not complete visible

is it possible to insert a dynamic size??

If you check the data in the AfterDataSetFilled to find how high your data goes or if you find the largest value outside the chart somewhere and pass it in, you can grab the yAxis in the beforeGeneration and set the left inset value for the label accordingly.

can u give me an example how to set the inset of a label?

Yeah. What's your BIRT version? I'll post a simple example.

Take a look at this example. Both charts have the same script changing the label values. The second chart has beforeGeneration script changing the axis label inset value. Hope this helps.
