# Mark subjects with selected disposition events in the waterfall plot

By default, the report marks only the occurrence of disposition events for a given subject on the spider/trend plot. If the Mark subjects with selected disposition events in the waterfall plot option is checked, then a black point marker is also used just above the best/last summary response value for a given subject in the waterfall plot provided the subject has any of the selected disposition events recorded.

Note: The value of the disposition event is based off the FIRST occurrence if there are multiple events selected.
