plotframe スケールとグリッドを指定してフレームをプロット. この関数は廃止されました.

## 呼び出し手順

    plotframe(rect,tics,[arg_opt1,arg_opt2,arg_opt3])

                plotframe(rect,<opts_args>)

## 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This function is obsolete.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")
