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")
