Hello,

What I was just looking for the combination of a Column and Line chart where half y axis is used. I must be dynamic, because I never know what type of chart the user will choose and over how many signals it will go. When I try the example, the result is not correct. It allows the Series F not see. This is a part of my code used.

Thanks in advance.
