Guideline: Do not use blow apart effects
Can I use the blow apart effect as feedback for a linked-view interface? As part of a dashboard, I have implemented a bar chart showing data from 20-50 sources. The color channel has been used to indicate the 7 categories of these sources. When one source is selected in another view, I move other bars on both sides of the selected source a little away. A visualization researcher told me that I should not do this as it is a blow apart effect. But what he suggested seems to be equally problematic (e.g., making thicker outline, changing size, animation, and so on). Please help.
