To add a second series along the y-axis, you will want to open the gear menu in the visualization, go to the Y-axis tab, and you’ll see series in the “left axis”. Drag one of the series to the “right axis” to create a secondary y axis for that series. This is described, with pictures, in our documentation here. We also have a video tutorial which outlines this process here. Let us know if you have any difficulties or have any followup questions!
How can I add the “right axis” to create a secondary y axis as a LINE?
(So the “left axis” = bar and the “right axis” = LINE)

Then, in the axis menu, you create a new Y axis and drag the relevant series to it, per that other example.
