plotframe Scilab plotframe
NAME
plotframe - plot a frame with scaling and grids
CALLING SEQUENCE
plotframe(rect,tics,[arg_opt1,arg_opt2,arg_opt3])
PARAMETERS
rect : vector [xmin,ymin,xmax,ymax].
tics : vector [nx,mx,ny,my] where mx, nx (resp. my, ny) are the
number of x-axis (resp. y-axis) intervals and subintervals.
arg_optX : optional arguments up to three and choosen among.
flags : vector [wantgrids,findbounds] where wantgrids is a
boolean variable (%t or %f) which indicates gridding.
findbounds is a boolean variable. If findbounds is %t,
the bounds given in rect are allowed to be slightly
modified (in fact always increased) in order to have
simpler graduations: then tics(2) and tics(4) are
ignored.
captions : vector of 3 strings [title,x-leg,y-leg]
corresponding respectively to the title of the plot and
the captions on the x-axis and the y-axis.
subwin : a vector of size 4 defining the sub window. The sub
window is specified with the parameter
subwin=[x,y,w,h] (upper-left, width, height). The
values in subwin are specified using proportion of the
width or height of the current graphics window (see
xsetech).
DESCRIPTION
plotframe is used with 2D plotting functions plot2d, plot2d1,... to set a
graphics frame. It must be used before plot2d which should be invoked
with the "000" superposition mode.
EXAMPLE
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")
