How to hide and then show an object when returning to a slide in keynote

Keynote does not have inbuilt tools that would show all the changes to the different highlight colours on the same slide.

A workaround can be used to show all the different highlights by adding extra slides.

You would need to add a minimum of 32 additional slides with appropriate content and hyperlinks to provide all the permutations you need. This takes time, effort and a lot of understanding. If you still want to do this in Keynote, I can show you an outline plan, however, I recommend using E-Learning or advanced Web authoring software, which can do what you want with ease.

Sorry for the delay, I missed your reply.

Keynote does not have the ability to use tool tips.

The way to do this is to add an additional slide containing the required content, some text, an image or a magnification of the bar chart is usual. Either move to that in the next slide or place a button with a hyperlink attached to link to the required slide.

Hyperlinks are created by right clicking the object and selecting Add Link > Slide.

You see this effect every day in TV news segments.
