Carousel Instead of Tabs
When creating multi-display visualizations, we need to provide a navigational element to our users so that they can switch between those displays. A common example of such an element on the web is a tabbed interface. Tabs allow us to name our various displays, giving the user an idea of what they should expect when clicking on a tab. Unfortunetly, due to limited horizontal space on mobile devices (especially in portrait mode,) we need to create an interface that switches between displays regardless of how many of them exist. One way to do so, is by introducing next/prev buttons.
For example, instead of tabs:
Try to use a carousel. This gives you more horizontal space to indicate what is currently being displayed. Grey out the previous or next buttons if there are no additional displays prior or next to the current one.
