The Plot Legends section controls the legend shown on the plot.
The legend communicates significance thresholds and category encodings. The tool does not automatically restyle markers by p-value; all significance annotation is configured here as manually defined legend items.
Show Legends
Enable Show Legends to display legend information on the plot.
Disable it if the legend is not needed or if the plot is too crowded.
Significance Legend
A common legend is used to show statistical significance.
Example:
| Legend Item | Meaning |
| Significant | p < 0.05 |
| Not Significant | p ≥ 0.05 |
Enable this option if you want the legend title to appear inside the plot.

The legend can be displayed in different layouts:
