Does anyone know if having a caption that identified important points in complex images or graphs are useful and what they should contain.

For example a screenshot demonstrates something, should that info be clarified also in text?

Is there any research on this?

Sometimes this information is in the alt text, should it be in a caption instead? 

All the best
