Picture musical notation, 5 horizontal lines where the y-axis is the note (higher on the staff, higher note) and the x-axis is position in time.
Say you have 5 event types, which occur with various frequencies over time. Plot them as dots on the staff.
Draw lines between events which link to each other.
If you draw the lines for the staff, they should be faint, only to help classify the event.
And you can of course have more than 5 event types, just add more lines. Hopefully less than 20 lines, otherwise this starts to get visually very messy.
