There is a diversity of applications which require analysis of data by comparing two
variables against each other. The graphical representation of data pairs(x,y) consists
basically of a collection of data points scattered across the chart area, rather than following
an equidistant progression along the x axis, as the previous examples have demonstrated
so far.
A scatter chart is made up of data points plotted against a horizontal and a vertical scale.
The 'x' and 'y' values positions are calculated against the horizontal and vertical scales,
respectively. An XY series consists of a sequence of data pairs(x,y), whose data points can
be displayed in different shapes, as a square, a circle, a triangle, a cross and a dot.
The number of values passed to the seriex_values parameter must always be a multiple
of 2. Every sequential set of 2 values is assigned to one data point, corresponding to the
x and y values.
The type of a xy series is 'xy'.
