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.

Exemplos

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