Is this interaction possible?

I mocked up the interaction and figured out how to create buttons that when clicked, change the color of the slices. Do either of you know if there's a way to let the user choose which slice the color (state) applies to?

For example, each slice will have a state for each of the color options. I want to have 4buttons to the side that lets the users apply the color to the slice, but I can't figure out how to indicate which slice the color should be applied to without having a button to select each color for EACH slice. So if I have 10 slices I would need 40 buttons (4 for each color option for each slice). That can't be right. Is there some advanced action I'm not aware of that would allow the last object clicked to have the state applied to it?

Hopefully that makes sense!

Thank you both for the responses! I'm glad to know this is possible.

Lilybiri, I'm using Captivate 9. I'm not 100% set on how I want the interaction to work, which is why I didn't provide more details. My rough plans are to provide users with a set of given information that must be added to the chart and corresponding colors that each item should be labeled. There would be 4 possible color choices. Users will then select the appropriate slice of the chart, and then choose which color it should be. When the user is done and clicks submit, the backend would verify that each slice is the correct color and let the user proceed to the multiple choice, or inform the user to continue trying.

You didn't tell which version you are using? If it is Captivate 9, I would create the segments as individual graphics, but each with as many states in different colours as you want to enable. You need an event to trigger the action to shade a segment, what did you have in mind? Clicking on a segment could be done, but how to define the color? First choosing a color from a color palette, then clicking on the segment? It needs a bit of reflection about the setup. There is no sequence imposed, which means that you'll have to use a (Boolean) to track: change it from its default value of 0 to 1. When all variables are changed to 1 you can show a Next button. Now another question: what is the link between the MCQ and the pie chart activity? You didn't give any explanation.

Too little details to give a more elaborated suggestion for a work flow.

Yes you could do this with Captivate by having all the segments of the pie chart created as separate graphics in each of the possible colours, positioning them over the top of each other, and then hiding all the coloured segments.  Your user would need to be able to click something to indicate which colour they want to select for a given segment and then the advanced action would be executed to UNHIDE that coloured segment.  You could track which one they selected with variables and then evaluate those variables with conditional actions to check that the correct answers were selected.

You are correct that this involves some fairly complex interaction, but it is possible to do.
