xrects Scilab Group Scilab Function xrects
NAME
xrects - draw or fill a set of rectangles
CALLING SEQUENCE
xrects(rects,[fill])
PARAMETERS
rects : matrix of size (4,n).
fill : vector of size n.
DESCRIPTION
xrects draws or fills a set of rectangles. Each column of rects
describes a rectangle (upper-left point, width, height): rects=[x1 y1 w1
h1;x2 y2 w2 h2;...]'. fill(i) gives the pattern to use for filling or
drawing rectangle i:
if fill(i)<0, rectangle i is drawn using the line style (or color)
-fill(i)
if fill(i)>0, rectangle i is filled using the pattern (or color) fill(n)
if fill(i)=0, rectangle i is drawn using the current line style (or
color).
EXAMPLE
plot2d([-100,500],[-50,50],[-1,-1],"022")
cols=[-34,-33,-32,-20:5:20,32,33,34];
x=400*(0:14)/14; step=20;
rects=[x;10*ones(x);step*ones(x);30*ones(x)];
xrects(rects,cols)
xnumb(x,15*ones(x),cols)
