Description:

Software to plot 2D graphs also supports surface graphs in 3D. Developed with Python using Tkinter for interface and Matplotlib.

Usage Explanation

python main.py

• PLOT button: plot data. For default you can plot many graphics in the same plot until you remove plots with CG or changing type of plot, from 2D to surface in 3D and vice versa.

• Funtion field: insert a valid function to plot in 2D with only x variable is allowed (y = f(x)), or surface to plot in 3D wich x and y variables only are supported (z = f(x, y)). All the variables and following functions are case insensitive. Functions and constant built-in supported are:

  • sin()
  • cos()
  • tan()
  • sqrt() (square root)
  • e, pi constants

  examples: 2D plot = sin(x) + 10, cos(x**2), sqrt(1/7), e**x 3D plot = sin(x) + cos(y), x**2 + y + 10

• C button: clear all fields.

• CE button: clear all plots.

• Range X or Range Y: Optionally insert a valid range of x and y (1, 10 for default) as integers separeted with comma.

• Sampling Interval: Optionally insert a valid sampling interval (0.01 for dafault).

• Title and axis names: Optionally insert name of axis and graphic.

Code explanation

• main.py Execution file. First create a frame and figure, put them together with canvas. Later calls App class from app.py

• app.py Contains App class within:

  1. creates tkinter interface along __init__ method,
  2. represent method which retrieve inputs from the user and prompt errors if user input something wrong,
  3. animate method plots data based on input user. If x range or y range wasn't provided, [1, 10] limits for deafult are taken. If sampling interval wasn't provided, 0.01 value is adopted. Plots surface in 3D if the user input function contains at least one y variable, if not try to plot in 2D along x var,
  4. graphs_clear delete axis object just to reset plotting view,
  5. fields_clear reset all input fields.
