No Data Show in the Graph

Troubleshooting > Problems with Graphs > No Data Show in the Graph

There are several possible reasons for this.

Perhaps the graph axes were rescaled beyond where the data lie. Choose Graph | Rescale Graph Axes to see if that fixes the problem.

Either the graph itself, or the collection the graph is connected to, might be filtered in such a way that no cases pass the filter. Filters are appended to the bottom of the object they filter. To see if the collection is filtered, enlarge it. Remove a filter by selecting the object and choosing Object | Remove Filter. Edit the filter by double-clicking it.

It is possible that you dropped a categorical attribute on a graph while pressing Ctrl (Win) Option (Mac). This has the effect of ignoring all non-numeric characters. If the attribute has no numbers, it will be blank.

Another possibility is that you have no data to graph. Perhaps you inadvertently deleted the collection, in which case you should Undo until you get it back. (If the graph’s name is “No Data,” this is what has happened.) It is also possible that you have not added cases to the collection, as when defining the attributes by random formula. Until you tell Fathom to create cases (Collection | New Cases), you have no data to display.
