Size of a point list
MuPAD® notebooks will be removed in a future release. Use MATLAB® live scripts instead.
MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.

Size represents the number of plot points
two data lists, displaying a set of plot points with coordinate values
given by quantile values of the data. By default, the number of plot
points is chosen as the minimum of the sizes of the two data lists.
In principle, however, the number of plot points can be chosen independently
of the data sizes. With
Size = n,
the number of plot points of the QQ plot can be set to any positive
integer value n.
The value of
Size can be animated.
We create a QQ plot:
data1 := [stats::normalRandom(0, 1)() $ k = 1..100]: data2 := [stats::normalRandom(0, 1)() $ k = 1..200]: qq := plot::QQplot(data1, data2): plot(qq)
By default, the minimum of the data sizes is chosen as the number
of plot points in the plot (i.e.,
Size = 100 in
this case). We reduce the number of plot points by setting the value
qq::Size := 30: plot(qq)
The number of plot points can also be specified directly by
passing the attribute
Size = n.
In the following graphics, this value is animated:
plot(plot::QQplot(data1, data2, Size = n, n = 10..200));
delete data1, data2, qq:
