Scilab Function 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This function is obsolete.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.
Examples
// 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)])
