Aggregated Metrics UI

[santosl529]

• make y-axis “min-by-min accuracy”
• remove title from the plot (ex. no “lachesis aggregated metrics”)
• stack vertically in compare rather than side by side
• no message box on hover: rather show all data of given user_id and dim the rest (highlight the user’s single line)
• x-axis: Parameter: greek delta_roam
• mean per user max line
• remove redundant legend in compare mode
