Interactivity-for tool tip of chart

nirmal792

Hello,

I am using BIRT 2.5 for creating charts.And m facing the problem for applying tool tip for report.i want to display my value data on tool tip with some rounding function on tht.

i.e BirtMath.round(value data *row[nodes])/100

but whenever i applies this function..its giving me error tht referencevariable value data is not defined.i also tried to do this by using globalVariable..but no success.

Please reply.

Hi Nirmal,<br />

Since this looks like an actual question, I'm moving this out of the Practice Area and into the Designing BIRT Reports forum.<br />

The variable name for getting the Value Data is 'valueData' without a space in them... however, I think I am seeing the same thing your are. If I use valueData by itself, everything displays correctly, however, using valueData within a formula is showing the same error you are seeing.<br />

Depending on how your chart is set up, you may be able to use the actual row value that you used to set up the Y axis data. For example instead of <br />
BirtMath.round(valueData *row[nodes])/100<br />
you may be able to use<br />
BirtMath.round(row[CreditLimit] *row[nodes])/100<br />
<br />
just replace CreditLimit with what you had selected for Y axis... this workaround will likely only work when you have only a single Y value for each X axis category.
