scatter plots
New in version 0.8.
scatter can be used to draw scatter plots. It uses matplotlib.pyplot.scatter and inherits all of its keyword arguments.
It should be used like this:
scatter(x_expr, y_expr, ...)
Where both x_expr and y_expr are (expressions returning) one-dimensional arrays (for example an entity field or
a groupby expression with only one dimension).
Optional keyword arguments include (among others, see above link):
• c: to set the color of each circle. A color will be assigned for each different value of this argument.
• s: to set the surface of each circle (mutually exclusive with the r argument).
• r: to set the radius of each circle (r=expr is equivalent to s=pi * expr ** 2). It is mutually exclusive with
the s argument. The r argument is specific to liam2.
Examples:
-
salary: 10000 + uniform() * 50000
area: 3.1415 * (4 + 1.5 * children.count()) ** 2
scatter(age, salary, c=eduach, s=area, alpha=0.5s, grid=True)
scatter(normal(), normal(), c=age, r=2 ** eduach)
