Stacked Columns Graph buttons not available SAP BI Mobile: 5.1.6

Hi, has someone faced this issue?

Not able to find this buttons or a equivalent :

to change from a chart style to another chart style (ie Bar or Columns graph to Stacked Columns Graph) using SAP BI Mobile

Environment: SAP BI Mobile: 5.1.6

Device:   IPAD

I'd like to know if this feature is not available?

For example SBOExplorer does show buttons like these, why not BI Mobile, or at least an equivalent?
