Hi Kris,
Great project but a bit out of date on Library usage. In order to make this work people will need to make the following changes:
Add this info to the beginning of the code:
#include <Wire.h>
#define SCREEN_WIDTH 128 // OLED display width, in pixels
#define SCREEN_HEIGHT 64 // OLED display height, in pixels

// Declaration for an SSD1306 display connected to I2C (SDA, SCL pins)
// The pins for I2C are defined by the Wire-library.
// On an arduino UNO: A4(SDA), A5(SCL)
// On an arduino MEGA 2560: 20(SDA), 21(SCL)
// On an arduino LEONARDO: 2(SDA), 3(SCL), ...
#define OLED_RESET 4 // Reset pin # (or -1 if sharing Arduino reset pin)
#define SCREEN_ADDRESS 0x3D ///< See datasheet for Address; 0x3D for 128x64, 0x3C for 128x32
Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET);

Remove the following code:
#define SSD1306_128_64
#define READ_PIN A0
#define OLED_RESET A4
#define LOGO16_GLCD_HEIGHT 16
#define LOGO16_GLCD_WIDTH 16
// create the display object
Adafruit_SSD1306 display(OLED_RESET);

Then the code runs great!

This code is fantastic! Does what it says on the tin - and exceptionally well documented/commented! Well done!!

Thank you for your willingness to share your project..👏👏👏

Wow Kris, thanks a lot, saved me a ton of time. I was beginging to write my own functions and i came across this video!

[MrBobWareham]

Thank you for your video and hard work making the software available for others to use.

[keest]

Thanks Kris! Will use this. I have been using part of your code in an antenna analyzer project. From your video using TFT displays.

Amazing functions, very useful... Thank you very much!

[mparkerlisberg]

Brilliant, thanks. I was looking for how to do what I was trying to do, but you did it for me.

Just learning but this definitely is a step In the direction I want ;) TY

[chimeranzl]

Legend! Thanks, saved me a lot of time coding the same up! Although if ylo is any number > 0 the X axis doesn't get drawn

[vikrampalsingh]

Thanks for sharing this. Really appreciate your efforts. Keep it up :)

[namibianbackyardengineerin]

Quick tip wenn explaining the code, zoom in so that we can see what's happening.

[danstancu]

Thanks alot! You should really put this into a library, don't think there is anything like it.

[upir_upir]

This looks great, thank you for sharing!

[ВладиславДудченко-яз]

Thank you, you did a really great work!

[nghiakhac]

Thank you Sir, It helps me build a similar project

[henrikh]

Thank you Sir, it is awsome work right there, much appreciated here in newbie lab :)

[rickmorenojr]

Kris Kasprzak, would you be able to increase your IDE font size in your next video. It's difficult to see. Otherwise, love the video. Thanks for sharing.

[rafaealhossain]

Hi, Kris! Loved the video. It works well. I was wondering how refresh and start replotting once the data hits the end of the screen? Can you suggest a modification to the code? It would be very helpful.
