OK, scrolling within a scrolling arrangement. Yep, doesn't always work.

You could try this extension:

Hi! first of all i speak spanish, so i apologize if my english is not good enough. I tried to make a column chart with data from firebase, but it doesn't seems to work, i swear i read all the documentation and try by myself but honestly i can't. i know my database is setted correctly. My problems are only the blocks. i just need to do a column chart with 4 columns that updates when i touch a button, and it should display the 4 int values into the columns, i know my problem is in the "list" part but i tried so many ways, so i return to the begining for this question, what should i do from this cap to do what i want? sorry if i am asking you something stupid. i need to siplay in the columns the first 4 tags from firebase, and keep it updated when i touched a button.

[TIMAI2]

Let us simplify to start off with. Based upon your displayed firebase data, your columnData should look like this:

If you apply this, do you get your column chart ?

If so you need to show how you are returning the firebase data to the app, and in what format.

[Rodrigo_Biolatto]

I started from the base y gave you in the first 2 pics to simplify the help you can bring me, so the first 2 pics i brought you is all i have, now i copy your pics exactly the same and i got the same pic you posted Also i don't have the "firebase blocks" because i thought it was extremely wrong so i delete that. i have my token and my firebase link correctly setted in the "designer" part, i know it because i can send int data from app inventor to firebase.
Edit: thanks for your soon reply.

Hi ! Me again, i tried my best but i still struggling with this, i came to an old post in this thread, and i intend to copy that, so this is the best i´ve got, but still not working, first pic it´s my blocks, second the image i tried to copy (this image it´s in some point in this thread). i hope someone can help me, thanks again. also i know my blocks are extremely wrong.

[TIMAI2]

This:

is all a terrible muddle

You need to build your columnChart in the Firebase.GotValue event

[Rodrigo_Biolatto]

sorry for that. It would be under the set "global plato" event, right? doing that, my chart doesn´t show any number in the "AguaGrande" column, it´s only an empty column. So with that modification, this is what i have.

[TIMAI2]

So what value is in your tag ComidaGrande? Set the value to a label so you can see it, or check your firebase data.

[Rodrigo_Biolatto]

In firebase, the tag "ComidaGrande" is 20, but in my chart seems to be 0, is an empty column. i´m thinking if could be a problem with the way i call the tag i the "call firebase. get value" event, is it okey to write it in that way ? or should i write a slash o something like "/ComidaGrande"

[TIMAI2]

Depends where that tag is in your firebase data

What is your projectBucket set to, and show your firebase data structure from the console

[Rodrigo_Biolatto]

i´m not sure what are you asking for, but this is my project.

and this are the properties

i want to highlight that i can write numbers from appinventor to firebase. under the "Dispensador_de_alimento" title, specifically in "OrdenAgua" and "OrdenComida".

[TIMAI2]

Set your ProjectBucket in the designer to empty / blank and try again

[Rodrigo_Biolatto]

i´m so thankfull, with that change it works ! Now to finish it, i should make the same with the other 3 tags. But i don´t know where i should put the other blocks to do the same without interfere between each other. i know the next pic is wrong, but i think showing it to you is the easiest way for you to correct my blocks, rather than talking in the air.

Again, sorry for the dumbs questions.

[Kevinkun]

in gotValue event, adf If tag=x, then....else if tag=y, then ....

and only when you get all data, then show chart.

[Rodrigo_Biolatto]

Hi Kevin, thanks for your answer. That´s actually my problem, i´m not sure how to get all data withouth interfere with the other variables. i´m not getting what you are telling me. Sorry. Also i don´t know if the "when boton_actualizar. click do" event is fine and the modifications i have to do are only in the .gotvalue event. i understand that the block i have to use is the "if, then, else" one but i don´t know where should i put it in the "gotvalue" event and how to fill it out.

[TIMAI2]

Do your four pieces of data have to be under the root of the structure, or can they go under a projectBucket e.g.

https://dogfeeder-70168...firebasio.com/
|
__ColumnChartData
    |
    |__AguaChico:13
    |__AguaGrande:32
    |__ComidaChico:2
    |__ComidaGrande:20
 

If so, you can call back all the data in one go and apply it to your chart accordingly

[Rodrigo_Biolatto]

if making that doesn´t interfere with my "writing blocks" that i have in another screen, it would be the same for me. these are the blocks i´m talking about:

i think it´s irrelevant but i´m asking you just in case.

[TIMAI2]

No, it will not interfere with those two items, although you could do the same thing for them as well....

[Rodrigo_Biolatto]

actually, i would prefer keeping those blocks under the main root because of my arduino code, but it´s easy to change the code according to that, nothing more than that, so if putting it under a projectBucket is way easier, let´s go on with that.
