plotframe

引数

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 chosen 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. Warning: the upper-case "C" is important.

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).

<opts_args>

This represents a sequence of statements key1=value1,key2=value2 ,... where key1, key2,... can be one of the following: tics, flags, captions ou subwin. These arguments have the same meaning as the ones used in the first form of the routine.

説明

plotframe is used with 2D plotting functions plot2d, plot2d2,... to set a graphics frame. It must be used before plot2d which should be invoked with the "000" superposition mode.

This function is obsolete.

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=tics,flags=[%t,%f],Captions=["My plot with grids","x","y"],subwin=[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,flags=[%f,%t],tics=tics,..

          Captions=["My plot without grids but with automatic bounds ","x","y"],..

          subwin=[0.5,0.5,0.5,0.5])

plot2d(x,y,5,"000")
