PlotIt

A terminal based tool to visualise mathematical functions.

Installation

Clone the repository using git clone https://github.com/djmgit/PlotIt.git
Enter into the repository and open in terminal
Run pip install -r requirements.txt This will install the only dependency (as of now) that is matplotlib, a python librarty to visualise graphs and PIL. If it is not working and is showing permission denied error, then try sudo pip install -r requirements.txt.
Tkinter library is required for GUI components, if it is not already installed then install it using sudo apt-get install python-tk
The project requires ImageTk. If it is not already installed then install it using sudo apt-get install python-imaging-tk

Thats it, you are all set to go !!

Using PlotIt

At present PlotIt takes 4 command line arguments and can be executed as shown below.

python plotit.py -f '[function]' -s [starting_abcissa] -e [ending_abcissa] -z [step_size]

It is to be noted that if function contains more than one term for eg x**2 + x then function should be under single quotes. Default values of starting abcissa, ending abcissa and step size are 0, 100 and 1.0 respectively

Some examples

python plotit.py -f 'sin(x)'

python plotit.py -f 'x**2 + x'

python plotit.py -f cos(x)

python plotit.py -f 'x**3 + x**2 + x'

python plotit.py -f 'exp(x)'

PlotIt GUI

PlotIt also provides a simple GUI to enter your function and visualise it. In order to use GUI instead of terminal use the command given below.

python gui_main.py

Before going for GUI mode, make sure you have installed Tkinter, PIL and ImageTk as mentioned above.
