twinkle

Arguments

h

handle or vector of handles of one or several graphical entities to blink. By default, the current graphic entity pointed by gce() is considered.

n

positive integer number: the number of blinks. Default n = 5.

Description

twinkle blinks n times graphical entities handled with h. If some of the objects are initially invisible, they are blinked with other ones and are finally left invisible before returning.

If twinkle() is run while no graphical figure exists, it does nothing and returns. If the handle h has some invalid components (the entity has been deleted in the meantime), twinkle(h..) yields an error.

Examples

clf
plot()
twinkle     // twinkles the last group of curves plotted in the plot() example
twinkle(3)  // twinkles it only three times

clf
x = linspace(-2*%pi,2*%pi,100)';
plot2d(x,[sin(x),cos(x)]);
e = gce();
p1 = e.children(1);
p2 = e.children(2);
twinkle(p1)       // cos plot twinkle
twinkle(p2,10)    // sin plot twinkle 10 times
twinkle(gca())    // axes twinkle

// Blinking a subset of many curves, with some initially invisible ones
clf
plot()
c = gca().children.children(1:10);
c(1:5).visible = "off";
sleep(5,'s')
twinkle(c)
