plotting two y-axes, lines and bars in one plot

[Simon]

Thank you very much for your effort, Eric!!!

Although I am sorry - I do not understand enough of scilab yet to 
understand exactly how this funtions work. Unfortunately the 
reverse-statement does not work with me.

Perhaps I did not integrate them correctly... I unzipped the files and 
copied them into .../scilab-4.1.2/macros/grocer/pltg_new/ and 
.../scilab-4.1.2/macros/grocer/prtgroc/ respectively.

Do I have to rebuild grocer anyhow to get it work?

greetings,
Simon
