    Cartesian graphing for ILI3941_t3 projects

    Add a Cartesian graph capability to your Teensy MCU projects. This library lets you plot up to 10 points and has auto screen updates when x exceeds the scale. You can also dynamically update the Y-axis should your measured values go out of bounds. Control colors, size and location. This library does require the legendary ILI9341_t3 display driver.

    Hope this helps you create cool projects with your Teensy!

    Dang, that's really slick and will definitely come in useful for me. Thanks for sharing that.

    Hi there, I have 'ILI9341_t3_controls (from your Github page) and the latest 'ILI9341_t3' libraries installed but when I try to run the Cartesian graph example I keep getting 'CGraph doesn't name a type'. I have tried this with T3.6, T4.0 and T4.1 and I am running Arduino 1.8.13 with Teensyduino 1.53 beta 3. I also have Adafruit GFX installed.

    Is there any additional requirements I need to add.

    Thanks

    not sure how it happened, but only part of the .h and .cpp files uploaded. I just re-uploaded the files. Please download again.

    I haven’t played with it yet but I am looking foreword to it. Big thanks for sharing not only this but the flicker free library.
    I have an RA8875 and a ili9431 I would like to try.
