| Location | Cause and Solution |
| «No graphic representation» | The selected combination of variables does not allow for any relevant charts. Review your selection: type of variables, number of variables, and whether they are X or Y variables. |
| The XY cloud does not appear | It requires exactly two quantitative variables. If there is one too many, or if there is a qualitative variable in the selection, it masks the result. |
| The 3D graph is not displayed | It requires exactly 3 quantitative variables. |
| The ROC curve does not appear | You need only one X, and a qualitative variable with exactly two categories to contrast with a quantitative one. |
| No test available | «Graphs Only» mode is enabled. Switch to «Provide Statistical Evidence.». |
| The test concludes that there is «no difference,» even though the discrepancy is visible | Check the matching and the sample sizes. With small samples, a real difference may still be statistically insignificant. |
| An illegible pie chart | Too many options. Switch to Bar or Pareto. |
