You can create one line chart to show the trend of whatever you are measuring and then create a cyclic dimension group which allows the user to step through or select the dimension that they want to see in the chart.
Then how do I add the two trends? meaning I have data where the 1st is time and the 2nd is the type of alert. What is a cyclic dimension? Visuals or links please. How would I add it given the above? Very nice about the groups! How do I add that to the above?
