In the proposed example, the concentration for the warfarin data set is presented.
- Segments : Add/remove the segments between the observations,
- BLQ (with the color): Add/remove the segments between the observations
- Legend: Add/remove the legend (available only if there are several groups on the figure),
- Informations : Add/remove the informations on the measurements (total number of subjects, mean number of doses per subject, total, average, min and max number of observations)

- It is possible to see the Spaghetti plot just after loading the datas. For that, click on the icon next to the data file choice.
- For a better understanding and/or exploration of the data set, it is also possible to export the data set in Datxplore.
