Vector the same length a X and y or a scalar. If s is a scalar,

MATLAB draws all the markers the same size. If S is empty, the

default size is used.

C determines the colors of the markers. When C is a vector the

same length as X and Y, the values in C are linearly mapped

to the colors in the current colormap. When C is a

length(X)-by-3 matrix, it directly specifies the colors of the

markers as RGB values. C can also be a color string. See ColorSpec.

SCATTER(X,Y) draws the markers in the default size and color.

SCATTER(X,Y,S) draws the markers at the specified sizes (S)

with a single color. This type of graph is also known as

a bubble plot.

SCATTER(...,M) uses the marker M instead of 'o'.

SCATTER(...,'filled') fills the markers.

SCATTER(AX,...) plots into AX instead of GCA.

H = SCATTER(...) returns handles to the scatter objects created.

Use PLOT for single color, single marker size scatter plots.

<stem> - Discrete sequence or "stem" plot.

STEM Discrete sequence or "stem" plot.

STEM(Y) plots the data sequence Y as stems from the x axis

terminated with circles for the data value. If Y is a matrix then

each column is plotted as a separate series.

STEM(X,Y) plots the data sequence Y at the values specified

in X.

STEM(...,'filled') produces a stem plot with filled markers.

STEM(...,'LINESPEC') uses the linetype specified for the stems and

markers. See PLOT for possibilities.

STEM(AX,...) plots into axes with handle AX. Use GCA to get the

handle to the current axes or to create one if none exist.

H = STEM(...) returns a vector of stemseries handles in H, one handle

per column of data in Y.

<stairs> - Stairstep plot.

STAIRS Stairstep plot.

STAIRS(Y) draws a stairstep graph of the elements of vector Y.

STAIRS(X,Y) draws a stairstep graph of the elements in vector Y at

the locations specified in X.

STAIRS(...,STYLE) uses the plot linestyle specified by the

string STYLE.

STAIRS(AX,...) plots into AX instead of GCA.

H = STAIRS(X,Y) returns a vector of stairseries handles.

[XX,YY] = STAIRS(X,Y) does not draw a graph, but returns vectors

X and y such that plot(XX,yy) is the stairstep graph.

The above inputs to STAIRS can be followed by property/value

pairs to specify additional properties of the stairseries object.

Stairstep plots are useful for drawing time history plots of

zero-order-hold digital sampled-data systems.

Contour and 2-1/2 d graphs

<contour> - Contour plot.

CONTOUR Contour plot.

CONTOUR(Z) is a contour plot of matrix Z treating the values in Z

as heights above a plane. A contour plot are the level curves

of Z for some values V. The values V are chosen automatically.

CONTOUR(X, Y, Z) X and Y specify the (x, y) coordinates of the

surface as for SURF. The X and Y data will be transposed or sorted

to bring it to MESHGRID form depending on the span of the first

row and column of X (to orient the data) and the order of the

first row of X and the first column of Y (to sorted the data). The
