.TH plotframe 2 "October 1994" "Scilab" ""
.so ../sci.an
.SH NAME
plotframe - graphic frame with scaling and grids
.SH CALLING SEQUENCE
.nf
plotframe(rect,tics [,arg_opt1,arg_opt2,arg_opt3])
.fi
.SH PARAMETERS
.TP 10
rect
:
vector \fV[xmin,ymin,xmax,ymax]\fR made of x and y bounds.
.TP
tics
:
vector \fV[nx,mx,ny,my]\fR where \fVmx, nx\fR (resp. \fVmy, ny\fR) are
the number of x-axis (resp. y-axis) intervals and subintervals.
.TP
arg_optX
: optional arguments up to three and choosen among.
.RS
.TP
flags
:
vector \fV[wantgrids,findbounds]\fR where \fVwantgrids\fR is a boolean
variable (\fV%t\fR or \fV%f\fR) which indicates gridding.
\fVfindbounds\fR is a boolean variable. If \fVfindbounds\fR is \fV%t\fR,
the bounds given in \fVrect\fR are allowed to be slightly modified
( in fact always increased )
in order to have simpler graduations (then \fVtics(2),tics(4)\fR are ignored).
.TP
captions
: vector of 3 character strings \fV[title, x-leg, y-leg]\fR.
.TP
subwin
: a vector of size 4 (sub window definition)
The sub window is specified with the
parameter \fVsubwwin=[x,y,w,h]\fR ( Upper-Left Width Height ).
The values in \fVsubwin\fR are specified using proportion of the width
or height of the current graphic window ( See \fVxsetech\fR ).
.RE
.SH DESCRIPTION
This function is used with plotting functions \fVplot2d\fR,
\fVplot2d1\fR,... to set a graphic frame. This function is
used before \fVplot2d...\fR which should be invoked with
the "000" superposition mode.
.SH EXAMPLE
.nf
x=[-0.3:0.8:27.3]';
y=rand(x);
rect=[min(x),min(y),max(x),max(y)];
tics=[4,10,2,5]; //4 x-intervals and 2 y-intervals
plotframe(rect,tics,[%f,%f],['My plot','x','y'],[0,0,0.5,0.5]);
plot2d(x,y,2,'000')
plotframe(rect,tics,[%t,%f],['My plot with grids','x','y'],[0.5,0,0.5,0.5]);
plot2d(x,y,3,'000')
plotframe(rect,tics,[%t,%t],...
['My plot with grids and automatic bounds','x','y'],[0,0.5,0.5,0.5]);
plot2d(x,y,4,'000')
plotframe(rect,tics,[%f,%t],...
['My plot without grids but with automatic bounds','x','y'],...
[0.5,0.5,0.5,0.5]);
plot2d(x,y,5,'000');
xset('default');
