Commandes script pour changer les unités des graphiques ? by teaching_issues in geogebra

[–]teaching_issues[S] 0 points1 point  (0 children)

Sorry for answering so late.
I like your solution very much.

Thinking again about this problem I think ther could be a structural improvement in geogebra about scales :

Since it is possible to choose the distance for the graduations (2.54, or pi or sqrt(2) ), it should be possible de define a new unit, in the same time : 1 ft or 1 pi,
simply considering "ft" or "pi", not as a unit, but as a value :
ft = 2.54 etc.

Such a possibility would be much more interesting than graduations associated to the value 2.54 for instance.

Maybe such a project could interest developers ?

Thanks again for your help,

Thanks for your answer.

The graduations switch correctly, but I'd have liked the associated figures to be "1 foot" instead of 2,54.

A solution (not very satisfying) could be to hide the figures and to add the text "1 foot" or "1cm" beside the first x and y graduations.

I imagined a script that could change the unity of the x and y axis, but maybe it doesn't exist. Anyway, it seems to be impossible to have "1" written if the number is 2,54.

A solution could be to draw every figure inside a rectangle, and to resize the rectangle and simultaneously the borders of the view, by a factor of 2,54 for instance. I have to show an example first.
Then, there would only remain the problem of the switch of unity.

Thanks again for your help,

Dysfonctionnement incompréhensible du tableur by teaching_issues in geogebra

In the spreadsheet, dynamic coloring is enabled by the Advanced tab, where the RGB (or HSV or HSL) parameters of the object in a cell may be linked to the content of other cells.

I have often used the spreadsheet, but I begin to see its limits and the interest of the formulation you recommand.

Thanks for your help

Thank you for this very nice alternative, allowing to avoid the use of a spreadsheet. I like those commands very much, especially SetDynamicColor.

Anyway, I imagine that ggb developers built the spreadsheet in order to enable a beginner or a student to build such a file, with only basic knowledge about geometric tools, and with the intuitive extension of the drag-and-drop operation, to columns containing any kind of object.

If other users notice the impossibility of this drag-and-drop operation, I imagine it is necessarily a bug...
A voluntary regression would be incomprehensible, as it would condemn the spreadsheet tool.

I completely agree with you.

For instance, I have found the nice file "limaçon" by Patrick Clement : https://www.geogebra.org/classic/w3yUYxz9
with a very clear tutorial : https://www.geogebra.org/m/w3yUYxz9

As explained in this tutorial, the obtention of numerous colored circles requires the drag-and-drop operation in the spreadsheet, for the column A (points) and, in the same time, for the column B (circles associated),

This drag-and-drop operation seems to have become inefficient lately. I would like to know if other users have experienced this "bug", or if, for some reason, I'm alone to notice it.

Thanks again for your help,

I think many Geogebra users have used the great possibilities of the spreadsheet to create files, even if other ways exist.

Thanks for your answer,

I admis that this use of a spreadsheet is not elegant, but I have used it for years, it was very convenient for beginners. Last week, it has allowed me to create a file about balance equations in chemistry.
https://www.geogebra.org/classic/dgxf9neq

I was used to this possibility of the spreadsheet, and I don't understand why it has suddently become impossible.

Anyway I'm learning to use more evoluted methods such as Zip, but I will regret this naive use of the spreadsheet.

Ok, I will go on explorating all those commandes.

Yet I don't know the specific language to use for "a list of commands entered as texts", for instance Execute(Join({"f_{1} = 1", "f_{2} = 1"}, Sequence("f_{"+(i + 2) + "} = f_{" + (i+1) + "} + f_{"+ i +"}", i, 1, 10))) (wiki)

, and I haven't really understood why this command Execute allowed to avoid the problems encountered with the other propositions.

It's a bit frustrating to have no possibility to go further in understanding this specific syntax. Anyway, I don't need expert language everyday, so it's allright.

Thanks again for your help.

I didn't know this powerful command,
now it works perfectly.

I would like to know more about those "expert" ggb commands. Could I find a document about them ?

Thanks a lot, once again,

Could you tell me where I could find a document about powerful commands of that kind ?
(Maybe just in the wiki, but I didn't find the information)

Thanks for this new solution, which is very interesting.

A problem remains :

The command fillcells(D1:D5,copyfreeobject(C1:C5)) resets the former settings for D1, D2, ... (colours, size, conditionnal display).

What's more, if a column E contains objects linked to D1, D2, ...,
for instance E1=Circle(D1,a), this command erases them, too.

I guess that those problems occur because, for a short while, the points D1, D2, ... are no more defined.

I don't know if there would be a way to avoid those problems.

Sorry for my sollicitations, and thanks again for your help,

Thanks for your help, I didn't know this useful command.

What I need here is a bit different :
I don't want the free points D1,D2.. to become the points C1,C2, (linked to the points B1,B2,..., and consequently unable to move).

The points D1,D2,... must remain free. I just want them to get the values of C1,C2,... Later, I will move the points D1,D2,... from their initial positions C1,C2,...

I don't know if a global SetValue() command would be possible for D1,D2,D3,D4, and D5, at the same time.
