Hi Ingrid , Thanks for providing the steps to use chart2 API for combining two chartype . I'll try implementing this method using the java UNO API .will get back to you if i face any eventual issues implementing the below method . Yes i'm aware of the risk using the unpublished chart2 API . our boss seems to be convinced that we should start using chart2 API . our project will be subject of future monitoring & re-factoring; so we will be tracking the changes in chart2 API and reflecting them in our java code.
I'll get back to you when i try your method described below. thanks for the help. othman Ingrid Halama wrote: > > Hi othman, > > Again a warning about using ::com::sun::star::chart2 API: It is not > provided for external usage yet.
