plot a single point how?

[kalle]

There is a line command to plot a line but no command to plot a point. Something like set point(x,y) is not available ? The workaround I use is the command for oval.
But the effect is that the drawing takes a lot of time...

some suggestion to improve would be helpful. EXAMPLE:

xscreen = 640
yscreen = 480

newPage(xscreen,yscreen)

def f(p, k) :
    fwert = p + k * p * (1 - p)
    return fwert
 
def input():
    global left, right, bottom, top
    global invisible, visible
    left = 1.8
    right = 3.0
    bottom = 0.0
    top = 1.5
    invisible = 200
    visible = 200
    
def setup():
    input()
    feigenbaumIteration()
    saveImage("~/Desktop/feigenbaum.png")
    
def setglobalpoint(xw, yw):
    x = (xw - left) * xscreen / (right - left)
    y = (yw - bottom) * yscreen / (top - bottom)
    oval(round(x),round(y),1,1)
    
def feigenbaumIteration():
    deltaxPerPixel = (right - left) / xscreen
    for section in range(0, xscreen+1, 1):
        coupling = left + section * deltaxPerPixel
        population = 0.3
        for i in range(0, invisible+1, 1):
            population = f(population, coupling)

        for i in range(0, visible+1, 1):
            setglobalpoint(coupling, population)
            population = f(population, coupling)
            
    
setup()

there is a work around

# create a bezierPath 
# this could collect all the points you want to show
p = BezierPath()
# add a point by moveTo and lineTo the same point
p.moveTo((100, 100))
p.lineTo((100, 100))
# add an other point
p.moveTo((100, 230))
p.lineTo((100, 230))

# set a stroke width
strokeWidth(28)
# set a line cap
lineCap("round")
# set a stroke color
stroke(0)
# draw the path
drawPath(p)

[frederik]

an example with a lot of random points

p = BezierPath()

for i in range(5000):
    x = random() * width() 
    y = random() * height()
    
    p.moveTo((x, y))
    p.lineTo((x, y))

strokeWidth(10)
lineCap("round")
stroke(0)

drawPath(p)
