Secondary Axis

Is there a way to plot 2 lines on a graph, with on primary vertical axis and one on a secondary axis?

Something like this:

I have some graphs in my home page.

I’d like to create an secondary axis for some of them, but I don’t find any solution for this. From a previous topic (https://ww.wp.xz.cn/support/topic/secondary-axis?replies=6) someone told that this is possible.

Any idea of how doing this?

This is my site: http://www.trabalhohoje.com.br

So, in this chart it have 2 axis:

– The primary is Population
– The secondary is members

From what I see, the numbers from 0 – 160 show the secondary axis. How can I input this to my graphic?

From this imagem, I believe it shows better: https://support.content.office.net/en-us/media/0c1a14c8-2dd2-4572-9367-5ebfd905970a.gif
