[ScatterChart2D] - General purpose node for Scatter Charts
|
|
|
|
A scatter plot (also called a scatterplot, scatter graph, scatter chart, scattergram, or scatter diagram)
|
|
is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables
|
|
for a set of data. If the points are coded (color/shape/size), one additional variable can be displayed.
|
|
The data are displayed as a collection of points, each having the value of one variable determining the position on
|
|
the horizontal axis and the value of the other variable determining the position on the vertical axis.
