A time period, a time duration within which the event inputs were received, is segregated into an ordered sequence of time slots. Inputs are categorized according to the time slots and the event categories. Ranks, based on weights of unique event inputs, are assigned to each of the predefined event categories within each of the time slots. A count of symbols for each time slot is defined. Each symbol represents a unique predefined event category. The time slots and the defined count of symbols ordered according to the ranks of the respective predefined event categories represented by the symbols for each of the time slots are displayed. Each symbol includes an indication of the weight of unique event inputs categorized for the selected predefined event category and for the selected time slot.
