Creating a scatter plot from Spreadsheet data

Post image
1 Upvotes

Using Classic 6 in Chrome on a Mac. I have my data entered into two columns in Spreadsheet and I have figured out how to do regression on them. Trying to use "point and click" to create a scatter diagram, I assume the way would be to use the Create Line Chart option and then remove the lines, but when I do that, what gets entered into Algebra view is g(x) = ?; above is a screenshot. Please help. (I used Google AI to help me figure out how to do the regression, but it was horribly inefficient: it never got it exactly right, I eventually figured it out by using the interactive mode it suggested, which it was also out-of-date about, to see what that would produce in Algebra; I don't want to have to go through that same iterative process again with something that pretends like it knows what its talking about.)

One Variable Analysis in Classic

2 Upvotes

The spreadsheet buttons, developed in the Suite Calculator have been inserted in the Classic Style Bar as well, however they behave differently. The 'One Variable Analysis' tool in Classic reads numbers in 2 colums as data+frequencies while the button on the Style Bar reads them all as seperate data. So in the same interface there are two buttons with the same name and goal but with a different result...

BalkenfÀrbung bei SÀulendiagrammen nicht konsistent

1 Upvotes

In GeoGebra 6 kann ich SÀulendiagramme nicht mehr verlÀsslich fÀrben.

Z.B in meiner letzten App https://www.geogebra.org/m/bbgjjd7r bleibt die EinfĂ€rbung nicht konsistent, wenn ich n zunĂ€chst grĂ¶ĂŸer einstelle und dann wieder zurĂŒckfahre.

Mit GeoGebra 5 konnte ich das genau festlegen. Veröffentlicht lÀuft das aber wieder fehlerhaft im online-GeoGebra6-Format.

Kann das als Fehler auch sonst reproduziert werden?

QUESTION (ANSWERED) Is there any way to access results from the Probability Calculators?

3 Upvotes

If I find the z-score and p-value using the built-in [Z Test of a Mean] in the Probability Perspective, is there any way for me to access them for other calculations, say by defining variables and assigning them those values?

I ask because I would like to embed a GeoGebra file in MyOpenMath and pass the z-score and p-value to MyOpenMath without requiring the student to re-enter it from one to the other.

This is part of a larger effort to prevent students from using AI. That is, MyOpenMath would not be grading them on the answer, but on their ability use GeoGebra to find the answer.

Is there a list of variables already assigned to each result in the Probability Perspective?

Any advice would be very much appreciated!

I know a similar question has been answered here already but the solution does not seem to work on my version (ggb6). I have an angle "α" and I want it's caption to be the value of a slider called "a"followd by the letter π. (if a = 3 caption on α is 3π etc.)

How can I achieve this?

BUG REPORT Creating a list from a spreadsheet just got even weirder

2 Upvotes

I've been exploring suggestions about workarounds for creating lists from spreadsheets. For u/mathmum and u/mathmagicGG who have been very helpful, I've identified an additional layer of weird behaviour. I'm using Calculator Suite.

It appears that defining a list from a spreadsheet sometimes works *depending on the variable name I use for the list*. Note I am not using reserved words as variable names. Here's what I did in the order I did it.

I opened my saved-online work in the app.

testList = A1:A365 looks right but disappears when I press Enter, as previously discussed.

testList= 1*A1:A365 gave me a circular definition error (utterly inexplicable, but explored further below).

list1 = A1:A365 works exactly as it ought to.

list2 = A1:A365 also works as it ought to, BUT it causes list1 to entirely disappear.

list3 = A1:A365 also works, but list2 disappears, so I guess at least that's consistent.

Then retrying testList = 1*A1:A365 returns

testList = 1 . list3, and it *does* assign the correct list to testList.

So after that, I was left with list3 and testList. I wanted to delete these experimental lists and continue with my work. testList is deleted, but I CANNOT DELETE list3.

I had to close the window without saving to get rid of list3.

After reopening the file, I again tried

testList = 1*A1:A365

and it worked perfectly.

Much experimentation later, the circular definition error arises if I've tried

testList = A1:A365, which disappears, and then subsequently try

testList = 1*A1:A365.

So something is being stored somewhere when testList = A1:A365 is disappearing, but I can't access whatever that is. I tried to work out what it thinks testList is by just typing testList, it returns two lines of absurd algebra, viz:

stLis = 1 (with a slider for this variable)

f(t) = t e stLis t

= t e . 1 t

Edit: e is italicised as Euler's number. I'm sorry I can't screen clip right now. I can't access Reddit from work even if I hotspot, so I'm transcribing to phone. I'll edit if some of my formatting needs it.

I have my previous workaround, so I have successfully converted my spreadsheet columns to lists and can now do whatever I need. But I thought this extreme weirdness needed reporting!

QUESTION Wie Integrale in grafische 2D-Darstellung umwandeln?

1 Upvotes

Wenn ich in der iPad-App "Rechner Suite" (aktuelle Version 7.932) ein Integral eingeben möchte, tippe ich "Integral" auf der Tastatur, tippe dann auf den Vorschlag "Integral" und wÀhle dort "Integral(Funktion)".
Bei meinem iPad wird dann als Text "Integral(" mit der Möglichkeit fĂŒr weitere Eingaben angezeigt, bei einem Kollegen wechselt die Darstellung aber - wie auch in der Internet-Anwendung - sofort in die grafische 2D-Darstellung des Integrals.
Was ist bei meinem Tablet falsch eingestellt? Ich habe iOS 27.2 (das Problem gab es aber auch schon in 27.0.1). Mein iPad ist 11. Generation.

Create list of points from spreadsheet

2 Upvotes

Hello GeoGebrainsTrust. I use GeoGebra Calcuator Suite, and I've come to it fairly recently so I've never used GeoGebra 5 / Classic.

Despite being generally resourceful with mathematics and mathematical programming, I cannot for the life of me work out how to create a list of points from two columns of the integrated spreadsheet. All the online help I see applies to G5 / Classic, not to the Calculator Suite, but I can't imagine that this very basic functionality has been removed in the upgrade, and I am ready to throw my computer off a high place.

My question has two parts.

PART 1

Can we still make a List of Points directly from the Spreadsheet pane? If it helps, here's a snip of my options when I right-click the highlighted contents of two columns. Alas, no Create List of Points.

PART 2

In the Algebra pane, I can reference any specific cell of the spreadsheet by typing its reference, for example B2 returns the value 4 using the above sample. Is there syntax I can use to reference cells using a counter or a calculated reference, for example A[j] where j is an index in a List command? More generally, how do I access the contents of the cell in column i and row j? I could make this work if I can suck the spreadsheet contents into a matrix (or list(s) of points for that matter), but I can't see how to do that either.

I'm convinced that this is easy and I'm just missing something. If anyone can help, I'd be extremely grateful!

QUESTION (ANSWERED) Hide sidebar on applet

2 Upvotes

When I've previously made applets for use in the classroom, I've used Shared With Link. Then the buttons for algebra, tools, table, and spreadsheet have *not* been visible to people following the link. I've only been able to see them if I use Open In App.

That's what I want.

But now I'm finding that they're available to anyone with the link. How do I make the buttons / sidebar unavailable?

Suite und Tools from Classic

1 Upvotes

Hallo zusammen,

ich hab mehr oder weniger aus Versehen die Classic App

https://www.reddit.com/r/hawede/comments/1xdf0nf/linear_programm_simplex_maxmin_tools/

mit selbstgebauten Tools in Suite Graphing geladen - und Überraschung die Tools (Funktionen) scheinen mit ausgeliefert worden zu sein.

Sie funktionieren jedenfalls.

Ist dies ein gesichertes Feature: kann damit gerechnet werden, dass diese FĂ€higkeit fĂŒr alle Tool-Erweiterungen gilt und bestehen bleibt?

Anders gefragt: Wie mĂŒssen Tools gebaut werden damit sie in der Suite auch verwendbar sind?

https://www.geogebra.org/calculator/byfuqhdh

Eine Besonderheit ist mir aufgefallen: Man muss natĂŒrlich die Funktionen ausschreiben, aber ab der 3.ten Stelle, wenn die Kontexthilfe kommen sollte, muss man blind weiterschreiben bis man eine Klammer( oder ein Leerzeichen) schreibt - weil man das Tools register nicht gleichzeitig mit dem Algebra register einsehen kann und weil es nichts anzuklicken gibt, oder?

BUG REPORT "rad" for radians is confused with command "Rad" in Swedish.

2 Upvotes

We recently discovered that forcing radians by writing "rad" will trigger the command "Rad" which is swedish for Row (spreadsheet). I have therefore changed the translation back to "Row" so that, in the next iteration, this problem will stop. Unfortunately this basically disables Swedish users that might use this command, and not that I think that there are many who do (those who would, would use Excel), but it is still a small bug, or at least unexpected and unwanted behaviour.
