newaxes

Arguments

h

Optional handle of the graphic parent of the new axes, of type Figure or Uicontrol of style Frame. By default, the current figure is used.

a

Handle on the newly created Axes entity

Description

newaxes() is used to create a new Axes entity (see graphics_entities) in the current figure or in the given figure or uicontrol frame.

The properties of this entity are inherited from the default_axes entity (see gda)

newaxes(h) creates the axes in the frame uicontrol or figure whose handle is h.

Examples

clf()
a1 = newaxes();
a1.axes_bounds = [0,0,1.0,0.5];
t = 0:0.1:20;
plot(t,acosh(t),'r')
a2 = newaxes();
a2.axes_bounds = [0,0.5,1.0,0.5];
x = 0:0.1:4;
plot(x,sinh(x))
legend('sinh')

sca(a1); //make first axes current
plot(t, asinh(t), 'g')
legend(['acosh','asinh'])

The following example uses newaxes(h)

// Create a new figure
f = figure("layout", "gridbag", ...
    "toolbar", "none", ...
    "menubar", "none", ...
    "backgroundcolor", [1 1 1]);

// Create the frames where each graph is put
c = createConstraints("gridbag", [1 1 1 1], [1 1], "both");
top_left = uicontrol(f, "style", "frame","constraints", c);

c.grid = [2 1 1 1];
top_right = uicontrol(f, "style", "frame", "constraints", c);

c.grid = [1 2 2 2];
bottom = uicontrol(f, "style", "frame", "constraints", c);

// Create the axes in each frame
a_tl = newaxes(top_left);
a_tr = newaxes(top_right);
a_bt = newaxes(bottom);

// Plot in the frames
X = (1:100) ./ 50;
plot(a_tl, X, X, "r");
plot(a_tr, X, cos(2 * %pi * 3 * X), "g");
plot(a_bt, X, exp(X), "b");

title(a_tl, "a line");
title(a_tr, "a cosine");
title(a_bt, "the exponential");
