plotframe
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.
Examples
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")
