Hi, I’ve made myself an application with a node.js server serial-connected to Arduino. The Arduino is collecting temperature data and the server sends it to a P5.js web-page and logs it to csv file. I’d like to show a graph of the csv data. In the web-page how do I ask for the file of data and get it into a table or array so I can plot it?

Check out [`loadTable()`](http://p5js.org/reference/#/p5/loadTable). The example shows you how to load in a .csv file. You might also have to use the [fetch api](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) if you’re csv file is on a server and not local.
Also Dan Shiffman recently made some videos about graphing using chart.js which might a quicker way to create some graphs if you don’t want to spend forever styling graphs in p5js. [Here’s a link](https://www.youtube.com/watch?v=5-ptp9tRApM&list=PLRqwX-V7Uu6YxDKpFzf_2D84p0cyk4T7X&index=6&t=0s) to that. Also the [1.2 video](https://www.youtube.com/watch?v=RfMkdvN-23o&list=PLRqwX-V7Uu6YxDKpFzf_2D84p0cyk4T7X&index=4) in that course is about parsing csv files that you get from the fetch api.
Hope that helps!

@figraham, thanks, I have something simple working with loadTable (worked without ‘fetch api’, just coming from the server’s folder. I haven’t spent much time formatting and I have started watching the video.
Thanks again.
