Split Y-Axis

The Split Y Axis button, allows you to have multiple Stacked y-axes.

Stacked Axes

For example, here the button has been clicked two times.

By default, this creates a stacked arraignment of graphs. Use the selectors on the right of each command to specify the axis location.

Joined Axes

The menu can also be used to Join the axes onto one graph, where the second axis shows on the right.

For example, here are two stacked graphs.

Change the menu to ‘Join Y’.
