How to align a sequence of texts to the right?

I have this sequence of texts:


I3=Sequence(Text("\begin{array}{r}" + (5i) + "\end{array}", l4(i + 1), true, true), i, 0, 25)


which refers to this sequence of points:


I4=Sequence((-2.1, k / 25 * 15 + 0.5), k, 0, 25, 5)


but it's actually intended to be the labels of these points:

I1=Sequence((0, k / 25 * 15), k, 0, 25, 5)


You can see that first 2 values have only one digit, and the others have 2 digits. This is a problem concerning text position. I have selected the I4 positions considering the 2 digit numbers, and so the others are not properly written.

I want the 1 digit numbers to be closer to points, so that they look like labels for this points (I am actually builiding an y-axis drawing, to be exported and put into a video - regular GeoGebra y axis is too small to be legible in the video).


What I need is to align the sequence to the right, not each point separatedly. Maybe a TableText can do that - I'm not familiar with its Syntax yet. I have read this article:

https://wiki.geogebra.org/e...

but I get confused about how to keep the relationship text-points AND add the TableText syntax at the same time.

OK

Use this version (for explor to understand) with Sequence() instead of Zip()

this?

sequence02=one line text per point

sequence03=multiline text per point

--------------------------------------

the text is horizontal shift leftwards from the anchor point

the multiline-text is right-justified in itself ( independently of the location of the anchor point)

It makes no sense to adjust single-line text in itself.

------------------------------------------------------

used commands:

Text()

TableText()

Zip()

Corner()

Thanks! That looks great. But I'm not getting to do that in my file.


I'm having some problem with file attaching, so I am providing my files with this link:

I copied your code and replaced the name of your list with mine, but it declares "Illegal argument"...

you should not copy the solution but you should understand the solution.

I'm trying to understand but it's hard.

I have checked the link you provided and it ONLY says this:


Zip( <Expression>, <Var1>, <List1>, <Var2>, <List2>, ...)


No explanation for what an expression is, what a variable is, what a list is. Only a few examples, very different from mine.

I have written this formula:


5i, i, 0, 25


So I don't know if I have to use it as EXPRESSION, or just put a sequence:

I2 = Secuencia(5i, i, 0, 25)


...and then call it from the Zip as if it was a list.


So:

Maybe <Expression> = 5i

or maybe <List1> = I2


Why would I need to write both?


An then... in <List2>, I'm trying to put I1 or I4 (which are lists of points), and it says Illegal argument.


So, let's start all over again:


Zip( <Expression>, <Var1>, <List1>, <Var2>, <List2>, ...)


What should I put in <Expression>?

What should I put in <List1>?

What should I put in <Var1>?

Data are: this formula 5i, i, 0, 25, and a list of points.

OK.

I have copied your sequence and replaced your list names for mine:

Secuencia(Texto("" + (l2(n)),I1(n) + (X pixX, Y pixX), true, true, -1, 0), n, 1, Longitud(l2))


I2 is my list of numbers 0,5,10,15,20,25

and I1 is my list of points.


It automatically creates sliders for n, X, Y


And it says: Illegal argument Texto"" + (I2(n))


I don't get why it does not accept my list.


See my attachments in this link: https://www.dropbox.com/sh/...

change I1 (upercase i) to l1 (lowercase L)

Thanks! That worked. I'm gonna avoid i/I and l/L letters from now on. Case gets easily confused. I will use B or other letter instead.

also remember that B1 or L1 are also addresses in the spreadsheet.

maybe L_1 or s1 or Li1 are better

Hi rami,

I'm trying to do something similar in another file, but I am not getting the same result. I don't understand the difference between your sequence and mine. Why is mine not alligned to the right?


I've tried both with Sequence and with Zip. Both do the same - correct text, correct point, alligned to the left.


Zip(Texto(n, (0 + X, y(i) + Y), true), n, T1, i, A8)


Secuencia(Texto(20 - 5i, (0 + X, y(A8(i)) + Y), true), i, 1, 3)


This was the sequence you did. I don't get which part of the sequence specifies that text should be on the right.

Secuencia(Texto("" + (L2(n)), L1(n) + (X pixX, Y pixX), true, true, -1, 0), n, 1, Longitud(L2))

Please give short answers to all the following questions.

Please do not give explanations or questions. Don't give anything but short answers.

question 1: how many parameters does the above command Text() have

---------------------------------------------------------------------------------------

Texto("" + (L2(n)), L1(n) + (X pixX, Y pixX), true, true, -1, 0)

question 2: how many parameters does the above command have

question 3: what is the value of parameter number 6

Question 4: what is the meaning of parameter number 6

------------------------------------------------------------------------------------------

Texto(20 - 5i, (0 + X, y(A8(i)) + Y), true)

question 5: how many parameters does the above command have

question 6: which value (-1 or 0 or 1) is taken into account for the horizontal alignment. (note: also consider that a default value could be taken into account)

question 7: What needs to be changed to get the desired result.

======================================================

Note1 : I can't evaluate it, because I don"t have the GGB file, but maybe it has some other errors.

Note2 : I will be back in the forum tomorrow.

para alinear un texto debe referirse a varias lineas una bajo otra pues en GG no tiene sentido alinear una sola linea de texto

esto se hace igual que haciamos con una matriz array en Latex o un tabletext() pero usando la letra r en lugar de la letra c segun hablamos en el post de centrar

otro asunto es el posicionar el texto respecto a un punto, esto se hace con los dos ultimos parametros del comando texto() que debe valer -1,0,1 segun se refiera a que el texto se posiciona a izq centro o der del punto, tal como estuvimos usandolo en dicho post
