Scatter Charts are good at demonstrating mathematical distributions, or when it is necessary to show a function of two variables, if they are independent or interdependent (when one of the variables is continuous).
This Scatter Chart demonstrates a series of 300 points and annotation of an interval type with adjustable horizontal boundaries. Annotations are special instruments for analyzing the data. The points that lay within this interval are being selected automatically when the boundaries are changed. There is a label showing how many points are held inside the interval and two select boxes, which values represent boundaries. Both Y-Axis and X-Axis values are between 0 and 240. Legend and grid are disabled on this chart. Tooltips display the name of the series in the title and rounded values of the point coordinates in the body part.
