plot2d1 Scilab Group Scilab Function plot2d1
NAME
plot2d1 - 2D plot (logarithmic axes) (obsolete)
CALLING SEQUENCE
plot2d1(str,x,y,[style,strf,leg,rect,nax])
PARAMETERS
str : is a string of length three "abc".
a : can have the following values: e, o or g.
e : means "empty". Itspecifies the fact that the value of x is
not used (the x values are supposed to be regularly spaced,
ie 1:<number of rows of y>). The user must anyway give a
value for x, 1 for instance: plot2d1("enn",1,y).
o : means "one". If there are many curves, they all have the
same x-values: x is a column vector of size nl and y is a
matrix of size (nl,nc). For example : x=[0:0.1:2*%pi]';
plot2d1("onn",x,[sin(x) cos(x)]).
g : means "general". x and y must have the same size (nl,nc).
Each column of y is plotted with respect to the corresponding
column of x. nc curves are plotted using nl points.
b, c
: can have the values n (normal) or l (logarithmic).
b=l : a logarithmic axis is used on the x-axis
c=l : a logarithmic axis is used on the y-axis
x,y,[style,strf,leg,rect,nax]
: these arguments have the same meaning as in the plot2d function.
opt_args
: these arguments have the same meaning as in the plot2d function.
DESCRIPTION
This function is obsolete. Use plot2d instead.
plot2d1 plots a set of 2D curves. It is the same as plot2d but with one
more argument str which enables logarithmic axis. Moreover, it allows to
specify only one column vector for x when it is the same for all the
curves. By default, successive plots are superposed. To clear the
previous plot, use xbasc. Enter the command plot2d1() to see a demo.
EXAMPLE
// multiple plot without giving x
x=[0:0.1:2*%pi]';
plot2d1("enn",1,[sin(x) sin(2*x) sin(3*x)])
// multiple plot using only one x
xbasc()
plot2d1("onn",x,[sin(x) sin(2*x) sin(3*x)])
// logarithmic plot
x=[0.1:0.1:3]'; xbasc()
plot2d1("oll",x,[exp(x) exp(x^2) exp(x^3)])
SEE ALSO
plot2d, plot2d2, plot2d3, plot2d4, xbasc
