The latest date is indicated on top of the plot.
If configured, 
data points belonging to the latest date are specially marked statistical averages are indicated by a solid line, and thresholds by broken lines outliers are marked by a red asterisk. They are defined as data points outside the
threshold lines "aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ ↓  you can download the data for each parameter set if the 'Data downloads' link shows up
