Scatter charts are related to line and area charts, but show the intersection of x and y values at each data point. These values appear on the scatter chart as a series of bubbles on a graph, based on the attributes you used when you built your report. You can then use a measure to color-code the bubble or use a measure to specify the size of the bubble. Drilling-down is accomplished by double-clicking on any data point on the chart.
Scatter charts work well to show the categorical relationship between two sets of numerical
measures, such as between a budgeted amount and the actual amount of money spent.
