Hello Chapman, thanks for your quick reply.
Actually the version I am working on is 1.28 in my on premise server, so I can't use 1.40 version. I tried to use library sap.viz.ui5.DualCombination, this worked well in desktop and I could combine bars not stacked and lines (I was based on this code dual chart / data merge - JSFiddle) , but this is an obsolete library and on phones doesn't work properly, so I discarded this option.
Do you know any other option that I could try to achieve what I need?
Thanks in advanced.
Jhon Jairo.
