13.5: Tabular Data - Processing Tutorial

[@UedersonThec]

Wow, bro! You know how to teach it! Would be great if I was a native english speaker! :) but I'm learning a lot from that video as a portuguese-br native speaker! It's a clear tutorial! Thank you so much!

[@netharuM]

you are super man in coding world

[@jespermadsen4348]

Love your energy, sir!

XML obviously stands for Xylophone Markup Language, considering the only word in the English language that starts with an X is "xylophone" and this is a well-known fact.

i am trying to use CSV files from a database, however the elements are separated by semicolons instead of commas, and some of the elements contain commas themselves. is there a way to tell processing it has to separate by semicolons?

[@benjaminevans8740]

Great instruction! Suggestion for another video: an intermediate stage between the first simple table used to draw a rectangle and the much more complex bubble object example. What about loading HappyFace, or FrownyFace svg files depending on the contents of the table, rather than just using circles? I've posted this as a question in the forum, if anybody has the same question.

I really love your videos and have learned so much from you. I have a question that I hope is a quick fix. I believe i am following the process you have outlined to place a txt file in my data folder and use the syntax above, however, i receive a NullPointerException error on the line of code where I use the loadTable function. Anything you might think of that I can try to resolve this? Thanks again for your great videos.

hello guys, can someone please give me the exact link for the code he is using.....I am not able to find it

[@jonnylaw4569]

So I'm having an issue, I made a csv file in notepad that I saved as test.csv However, when I try to read the data in that csv file, it says "test.csv does not exist or could not be read" "NullPointerException" Do I need to put in a directory path or something? If so, how would I do that?. This is my code currently- Void setup() { Size(500,500); } Void draw() { Background(0); Table table = loadTable("test.csv"); TableRow row = table.getRow(0); Float x = row.getInt(0); Float y = row.getInt(1); Float w = row.getInt(2); Float h = row.getInt(3); Fill(255); Rect(x, y, w, h); } Edit: Ok I found out what I needed to do, it wasn't my program that was wrong, it was where I saved the csv file. For those who have the same issue as I do, save the csv file in the same folder as the program that uses it

[@lukem118]

Your technically suppose to save it in the data folder. Use Sketch>Add File at the top of the Processing editor.

[@jonnylaw4569]

@@lukem118 ah ok, yeah I couldn't figure it out so I just messed with it until I found something I could work with

[@ai_zj]

Quick tip for others.. Drag the file onto your actual Processing sketch.

[@forresterickson6225]

So here I am December 2019 and have an application where a table might help me. Having never before worked with table I started with the example at: processing.org/reference/Table.html This example produces an error when I try to run it: The function addColumn(String) does not exist. Anyone else working with tables encountered this and found a fix? Really had to get started when the examples from Proccessing.org do not work. I am using Processing version 3.5.3.

[@TJ-zs2sv]

Can u Please put the link to source code?

[@pattala3478]

Could you tell me how to receive the column data from the csv. file , I want to create the graph from column data.

[@anodic_passion]

hello sir, i am stuck with a problem... i have a csv file and i want to search for a string in its first column and then want to display the whole content of that specific row on screen... please help me out...

[@anodic_passion]

sir please help me out...

[@moritzklug1858]

But how do you find a certain data and delete THAT row ?

[@AndyHHH7]

How can I create an XML file with processing?

[@AndreSantos-hx9qy]

Thanks Daniel for the info, you are very clever and explicit in your explanations. Been learning a lot from you. Currently i´am programming a Paint Editor and an table like this it´s very useful, however i couldn´t yet put the function to call the table. Trying to put like a save function to the drawings that its drawn.

[@TheCodingTrain]

+Andre Santos Are you using Processing 3? With older versions of Processing some of this code will not work.

[@AndreSantos-hx9qy]

I´m currently using P3. I got the table to record what i draw., in the csv file The table updates until 10 rows, im stuck here. I want to create a button to import the data saved in csv to be able to continue the work, after closing the program.

[@TheCodingTrain]

+Andre Santos Sounds like this a more complex problem than what can easily be discussed in youtube comments. I would suggest making a post at forum.processing.org and link from here so I can follow!

[@AndreSantos-hx9qy]

Ok ill do that...thanks

[@maissahamdi6029]

hi I really admire your work, I would appreciate if you help me with a programme that receive data from arduino to processing and class them in a table

[@andrewkiminhwan]

in p5.js, do dates in the form of integers separated by Slahes "/" count as Integer? or String?

[@TheCodingTrain]

+andrew kim If they include slashes they would have to be a string (unless they are already some other JS object like a "Date" object or something). But I would assume string here.

[@SimplyProd98]

can we get a p5.js version please :)

[@rubyruby9425]

Very useful, thanks a lot

[@JulianBejarano]

you are the best

thank you my bro! Love ya (mua >3
