Input Controls in Graph Charts

Hi,

We have succesfully used input controls acting on vertical tables (see at http://scn.sap.com/docs/DOC-35272 ). But when working with graph charts instead of tables the filter icon does not appear in the iPad.

Has someone used input controls with graph charts succesfully?

We are using release 4.0 SP4 patch 8 (iOS Client 4.4.18.11 (219411))

Regards
