.TH plot2d1 2 "April 1993" "Scilab Group" "Scilab Function"
.so ../sci.an
.SH NAME
plot2d1 - 2D plot (logarithmic axes) (obsolete)
.SH CALLING SEQUENCE
.nf
plot2d1(str,x,y,[style,strf,leg,rect,nax])
.fi
.SH PARAMETERS
.TP 5
str
: is a string of length three \fV"abc"\fR.
.RS
.TP 3
a
: can have the following values: \fVe\fR, \fVo\fR or \fVg\fR.
.RS
.TP 3
e
: means "empty". Itspecifies the fact that the value of \fVx\fR is not used
(the \fVx\fR values are supposed to be regularly spaced,
ie 1:<number of rows of \fVy\fR>). The user must
anyway give a value for \fVx\fR, 1 for instance:
\fVplot2d1("enn",1,y)\fR.
.TP
o
: means "one". If there are many curves, they all
have the same x-values: \fVx\fR is a column vector of size nl and \fVy\fR
is a matrix of size (nl,nc). For example :
\fVx=[0:0.1:2*%pi]'; plot2d1("onn",x,[sin(x) cos(x)])\fR.
.TP
g
: means "general". \fVx\fR and \fVy\fR must have the same size (nl,nc).
Each column of \fVy\fR is plotted
with respect to the corresponding column of \fVx\fR. \fVnc\fR curves are
plotted using \fVnl\fR points.
.RE
.TP
b, c
: can have the values \fVn\fR (normal) or \fVl\fR (logarithmic).
.RS
.TP 5
b=l
: a logarithmic axis is used on the x-axis
.TP
c=l
: a logarithmic axis is used on the y-axis
.RE
.RE
.TP
x,y,[style,strf,leg,rect,nax]
: these arguments have the same meaning as in the \fVplot2d\fV
function.
.TP
opt_args
: these arguments have the same meaning as in the \fVplot2d\fV
function.
.SH DESCRIPTION
This function is obsolete. Use \fVplot2d\fR instead.
.LP
\fVplot2d1\fR plots a set of 2D curves.
It is the same as \fVplot2d\fR but with one more argument
\fVstr\fR
which enables logarithmic axis. Moreover, it allows to specify only one column
vector for \fVx\fR when it is the same for all the curves.
By default, successive plots are superposed. To clear the previous plot,
use \fVxbasc\fR.
Enter the command \fVplot2d1()\fR to see a demo.
.SH EXAMPLE
.nf
// 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)])
.fi
