Hello, Would anyone be able to give some pointers on how to create a chart with time bandings on the X axis and aggregated values on the Y axis? For example, consider this data: time user 100 X 100 Y 110 X 110 Z 120 Z 130 Y 130 X 130 Z Would produce a graph with (for arguments sake) four time bands with values: 100-110: 2 110-120: 2 120-130: 1 130-140: 3 Of course, I will have lots of time data and the bands will be controlled by the 'Time period' drop down in a 'Time series dataset'. Any thoughts would be most welcome. John
