Denzven-Graphing-Api is my first flask project that plots graphs of formulas/Equations using python. i have also made and Api-Wrapper (mostly for practice) to make life easy and to use this Api.

Using the Api is as simple as sending a request to the website with some params such as the fourmula ,grid ,plot_stylee ,x_coord ,y_coord (and more params coming..) and the Api will return an image of the plotted Graph.

http://denzven.pythonanywhere.com/DenzGraphingApi/v1/flat_graph/test/plot?formula=x%2By&x%2By&grid=1&plot_style=3&x_coord=20&y_coord=20

Note:

• Base url:
  • http://denzven.pythonanywhere.com/DenzGraphingApi/v1/flat_graph/test/plot
• the formula:
  • ?formula=x%2By&x%2By

    Note that this url is “urlencoded” using urllib.

  • what can the formula contain?
    • trignometric functions:

      sin() cos() tan()

    • powers

      x**2 = x²

    • Basic BODMAS

      ()=Brackets,
      /=Divide,
      *=Mutiply,
      +=Add,
      -=Subtract

    • Misc:

      pi=value of the const pi,
      sqrt()=square root of the value,
      %=modulos gives the remaider of the divsion

      • eg: 2%6=0 and 2%(10)=0
• the params:
  • &grid=1

    grid refers to the presence of smaller grid lines, 1 is true and 0 is false

  • &plot_style=3

    these are a list of the default plot_styles it can range from 0-25

  • &x_coord=20

    the value ot the x coordinate (horizontal)

  • &y_coord=20

    the value ot the y coordinate (vertical)

The api has several limitations in its use now, and is slowly getting patched/fixed.

Some Known ones:

• limitations in the formula usage: the formula must equate to zero.
  like “x+y” as input will mean the graph of “x+y=0” and it must contain bot x and y in the equation.

I dont know of any other feel free to add them in!

• Fork the repository
• Clone your fork: git clone https://github.com/denzven/Denzven-Graphing-Api-Bot.git
• Create your feature branch: git checkout -b my-new-feature
• Commit your changes: git commit -am 'Add some feature'
• Push to the branch: git push origin my-new-feature
• Submit a pull request

• there was a bug by putting exit() or quit() in the formula that would turn off the api.. i have tried my best to patch it

I dont know of any other feel free to add them in!

I am a 17 year old wierdo that hops on with tons of hobbies and gets bored easily. Tried out a bunch of stuff like blender3D, voxel art, making discord bots and telegram bots, basic python programs, right now i am making an Graphing API and its wrapper. you can find more info about me here

Thank you! Hope You can tribute much needed support and enjoy using the api as much i did making it 😁
