## Parâmetros

area

  matrix `[xmin xmax ; ymin ymax]` or `[xmin xmax ; ymin ymax ; zmin zmax]`, or row `[xmin ymin xmax ymax]` or `[xmin ymin zmin xmax ymax zmax]`: new bounds of the area to be reframed.

  - `%nan` can be used to keep a bound as is.
  - `%inf` can be used to set a bound to the position of the most marginal graphical component existing in the axes, for the considered direction.
  The default area is [%inf %inf %inf %inf] for a 2D axes, or [%inf %inf %inf %inf %inf %inf] for a 3D one.

  If N axes are identified in `idAxes`, `area` may be a matrix with N rows and 4 or 6 columns. The row #i is then related to the axes #i of `idAxes`. If `area` is only a vector of 4 or 6 bounds, these ones are used for all axes to be reframed.

idAxes

  Vector of graphic handles, expected to be of Axes type or to have direct children of type Axes, such as Figures or some frame uicontrols. `idAxes` specifies direct or children Axes to crop. If no axes is found, nothing is done.

  By default, the current Axes is considered.

tight_limits

  Single word `"tight"` or `"on"` or `"off"`, or vector of 2 (in 2D) or 3 (in 3D) words `"tight"` or `"on"` or `"off"`. If a single word is provided, it is used for every axis. This option forces the `.tight_limits` attribute of considered axes to the specified `"on"` or `"off"` values. By default, current limits modes are unchanged.

## Descrição

`replot` is used to reframe the (set of) axes specified with `idAxes` -- or by default the current axes -- with new boundaries defined in 2D by `[xmin xmax ; ymin ymax]` or `[xmin xmax ; ymin ymax ; zmin zmax]`, or in 3D by `[xmin ymin xmax ymax]` or `[xmin ymin zmin xmax ymax zmax]`.

It changes the `data_bounds` attribute of processed axes.

When a specified bound is infinite (%inf and -%inf are equivalent), `replot` looks for the most marginal graphical object and sets the actual related bound to its position, taking also objects sizes into account. This ensures not clipping any object that would be beyond the targeted side of the axes.

When the `tight_limits` option is provided, its value is assigned to the `.tight_limits` attribute of each considered axes, in an axis-wise way.

gca() always refers to the same axes before and after calling replot(..).

## Exemplos

    // primeiro exemplo
    x=[0:0.1:2*%pi]';
    plot2d(x,sin(x))
    replot([-1,-1,10,2])

x=[0:0.1:2*%pi]'; plot2d(x,sin(x)) replot([-1,-1,10,2])

    // segundo exemplo
    close(winsid());
    plot() // plot demo
    f=gcf();
    replot([-1,-1,10,2],f.children(1)) // especificando o valor do manipulador dos eixos
    replot([-3,-2,8,4],f.children(2))

close(winsid()); plot() f2=gcf(); replot([-1,-1,10,2],f2.children(1)) replot([-3,-2,8,4],f2.children(2))

    // Os fronteiras indicadas pelo valor %nan não são alterados:
    x = linspace(0,360,200).';
    clf
    plot2d(x,[sind(x) tand(x)])
    ax = gca();
    ax.data_bounds              // Fronteiras iniciais
    replot([%nan,-10,%nan,10])  // Ymin e Ymax só são modificados
    ax.data_bounds              // novas fronteiras

    // 3D Fronteiras Z também pode ser modificadas :
    clf
    x = linspace(-4,4,100);
    X = meshgrid(x);
    R = (X-0.5).^2 + (X.'+0.7).^2;
    Z = sinc(R);
    surf(x-0.5,x+0.7,Z)
    f = gcf();
    f.color_map = autumncolormap(100);
    ax = gca();
    ax.data_bounds
    sleep(3000)
    replot([-5 0 -0.4 0 5 0.5])
    ax.data_bounds

    // Diversos gráficos podem ser cortadas simultaneamente :
    clf
    x = linspace(-%pi,%pi,400);
    subplot(2,2,1)
    plot2d(x,sin(1 ./sqrt(abs(x))))
    ax1 = gca();
    subplot(2,2,2)
    plot2d(x,sinh(sqrt(abs(x))))
    subplot(2,1,2)
    plot2d(x,cos(1 ./sqrt(abs(x))))
    ax2 = gca();
    sleep(4000)
    f = gcf();
    replot([-1 %nan 1.5 %nan], [ax1 ax2])
