XY Chart With Colored Symbols Indicating A Third Variable

Data set has three columns: dates, cycle times for event and event type. I want to create a XY chart with cycle time ploted against date (filled circles connected by line). I further want the color of each of these symbols to change as a function of event type. I vizualize a chart where the symbols might be red, red, blue, red, yellow where red indicates event type 1, blue event type 2 and yellow event type 3. how I might build this chart.
