Hide chart in Pentaho Report Designer if not data

Question

We are setting a chart on Pentaho Report Designer 5.3 and we want it to hide if no data is returned by the query, aligned to that chart.

We have used, the:

=NOT(ISEMPTYDATA())

in the visible style expression but it shows

chart_user_no_data_available

on the chart, and it is not working.

How do I solve this?

=YourFunction
