Bubble Chart in Report Editor
Similar to scatter plots, bubble charts offer added functionality: the size of the plotted points can be set to change in proportion to the magnitude of a third metric.
In the following chart, the position of a bubble along the x-axis indicates one metric value, while its position up the y-axis indicates a second metric value. The bubble’s size indicates a third metric: the relationship of the Expected + Won value to the quota, which is indicated by the size of each bubble.
To display a report as a bubble chart, from the Report Editor, select Bubble Chart from the list of chart icons:
