Hover label graphs can be displayed when the cursor is moved over a graph element in a graph produced with JMP® software. If you place a column in the "Group X", "Group Y", or "Page" role in the JMP Graph Builder platform and you opt to display a hover label graph then the hover label graph is misleading. In the situation described, the internal data filter Where() clauses completely ignore the grouping information. The hover label graph presented actually shows the data without considering the grouping. As a possible circumvention, you can add the grouping column as an Overlay column instead, and the hover label graph represents the expected data.
