(1) The scatter diagram shows the main direction of depolarization during a period of time.

(2) The method trainings in the teaching materials infiltrated into the various activities could be described on scatter diagram, the number proportion of activities could be described on histogram.

(3) The piecewise polynomial regression model was established based on analyzing the scatter diagram of the speed change with the install distance.

(4) Unless otherwise stated in the design brief, the North Atlantic scatter diagram should be used in ULS and FLS for unrestricted world wide operation.

(5) This model can be as easy as one input variable and one output variable (called a Scatter diagram in Excel, or an XYDiagram in OpenOffice.org).
