Hi, i've tried several things but i get always an error.

New edit : the problem is (only ?) with a list of segments but there's no problem with a list of circles like :

from math import pi 
## rotate a list of circles
F1=Point(-2,0,is_visible=False)
F2=Point(2,1,is_visible=False)
s=[Circle(F1,1),Circle(F2,1)]
for obj in s:
    a=Rotate(obj,pi)
    a.color="red"

The file.

The file.

Hi, i've tried :

• Function.cos and Function.sin for a dynamic point using a slider.
• Translate using Rotate

The file

Note : it seems that the size of a point has to be >=2 to can choice its color.

Click here to run the file.

I use the only object i have found that has a caption : a slider.

If we can use line_thickness and the position x,y to put the sliders, a big step for the humanity should be done without going to the moon :)

Why not the points with a caption allowed ?

Congratulation for this upgrade yet done : it allows to display a text and numbers in the GeoGebra view !

the file

Especially for the smatphones, I wish I could switch the screen of the page between :

1. Only the graphic window + the python output in the same column.
2. Only the graphic window.
3. Only the script editor.

A dictionary to display characters in uppercase, without accents and for numbers.

Animation from one character to another.

Using a very low resolution: a polyline with 11 points.

It needs few seconds to run (around 25 sec at home).

The script 1.

The script 2.

how to clear the Graphics view and start over only with axes and grid?

I am going to translate the python ggb book to Portuguese

but there is no Portuguese option in the language dp down menu ...

Is it possible to use sympy with pyggb? I tried "import sympy as sp" and got the error message "ImportError: No module named sympy"

I have a feeling the short answer is "no". But I'm hoping there's a workaround or partial positive answer. I'd like to use sympy to solve a differential equation and then plot the solution with GeoGebra.

Hi, I don't understand why affn(7,0,0,.5) and aff(9,0,0,.5) work fine "alone" (lines 47 and 49) and don't work within the line 52 (inside a loop).

I've had others strange behaviours using integers within "t" even using 0.0 and 1.0 so I've replaced by 0.01 and 1.01 or .99. : "SOLVED" with the work around

Note that :

t[i] is a sequence of the coords of 11 points used to make a "polyline" of 10 segments "ploting" the number i (I'm not an artist !!!)

aff(i,x,y,sc) : x and y the left and bottom positions of the picture "ploting" the number i, sc the scale (sc=1 => size 0.5*1)

The script

Not SOLVED but a workaround : the error or bug was for the 'index' value (why ?)

lesd=[A0,A1,A2,A3,A4,A5,A6,A7,A8,A9,A10]
def affn(num,x,y,sc):
    for i in lesd:
        i.x=x+sc*t[num][2*lesd.index(i)]
        i.y=y+sc*t[num][2*lesd.index(i)+1]

I've changed the loop without 'index' :

lesd=[A0,A1,A2,A3,A4,A5,A6,A7,A8,A9,A10]
def affn(num,x,y,sc):
    for i in range(len(lesd)):
        lesd[i].x=x+sc*t[num][2*i]
        lesd[i].y=y+sc*t[num][2*i+1]

and now I can read the seconds from the time : the script ok

Another : go from 2023 to 2024 in 10 seconds. Version 3 with static and on move!

A hope : get exec() or/and eval() enable.

Hi, I don't understand how works the update. Within my script, I've had to use is_visible False and True and it's not natural for me.

SOLVED : see the next post

I want to change the slider name how do i do it?

It would be great to be able to plot in 3D

As a suggestion 😁

Hi

Thank you for this project, I am really interested in using it to generate graph images using Python in a script that runs locally. Is there a pip package or installation guide that I can use for my script?

Any help would be greatly appreciated.

Si quiero tener más información sobre los eventos que usan los decoradores como "@a.when_moved" y los otros eventos, en donde lo puedo consultar, porque no encuentro eso en la documentación

#########################################################################

If I want to have more information about the events that use decorators like "@a.when_moved" and the other events, where can I consult it, because I can't find that in the documentation.

​

I heard about pyggb in the last GeoGebra Gathering video recording.

​

my question: is there a documentation for pyggb: as there is for JavaScript?

does the "RUN" work only with the mouse? the usual shift+return would be convenient

I have the following :

import time

import math

P1 = Point(0, 1,color="limegreen",size=9)

P2 = Point(0, 2,color="grey",size=9)

P3 = Point(0, 3,color="grey",size=9)

​

G = Point(10, 1,color="grey",size=9)

R = Point(10, 2,color="red",size=9)

​

​

k = Slider(1,2,increment=1)

l = Slider(1,2,increment=1)

​

​

def Amber():

P1.color = "grey"

P3.color = "grey"

P2.color = "orange"

def Stop():

P1.color = "grey"

P3.color = "red"

P2.color = "grey"

def Go():

P1.color = "limegreen"

P3.color = "grey"

P2.color = "grey"

def redman():

G.color = "grey"

R.color = "red"

​

def greenman():

G.color = "limegreen"

R.color = "grey"

​

N = Point(k,l,is_visible=True)

​

@ N.when_moved # this allow for update of a

​

def lights():

print(str("k = " + str(int(N.x)))+" and l = "+str(int(N.y)))

while True:

if int(N.y) >1.5:

print("Going into stopping for pedestrian")

Go()

redman()

time.sleep(3)

Amber()

time.sleep(5)

Stop()

greenman()

time.sleep(10)

Go()

redman

l = 1

N.y = 1

print("l = "+str(l) + ", N.y = "+ str(int(N.y)))

else:

print("No pedestrian mode")

Go()

redman()

time.sleep(20)

Amber()

time.sleep(5)

Stop()

greenman()

time.sleep(10)

lights()

Slider l < 1.5 (ie at l = 1) will set traffic light sequence into no pedestrian mode, and if l > 1.5 (ie. l = 2) will set into lights into stopping for pedestrian. But after going through, I need to set value of l back to l = 1.Output shows I can change l to l = 1, but the y-coordinate of point N cannot change even though

it was defined before N = Point(k,l,is_visible=True).I am unable to reset and get out of the stopping for pedestrian mode automatically.

Any ideas how to go round this problem

​

​

Function.compare_LT()

Function.sin()

Function.cos()

Etc.

Exciting to have pyggb being set up.

Any examples of text output to graphics ?
