Assignment- plotting-1

Create a single pdf file with question and output and share it in group. File name rollno-name 


1.Create a matplotlib plot with two lines representing the functions y=sin(x) for

0≤x≤2π (use a solid line) and y=cos(x) for 0≤x≤2π (use a dashed line).

Customize the plot by adding appropriate ticks, labels for the x and y axes, and a

legend to distinguish between the two functions. Set the title  “RollNo  Name”.

 

2.Plot the function y=x^2 and y=sig(x)   as two separate graphs with suitable legends, labels and a Title with your roll number and name. Lean about sigmoid function. Popular function used as activation function in machine learning

https://en.wikipedia.org/wiki/Sigmoid_function

 

3.Write a Python program to plot the bar graph to depict the popularity of various programming languages. Label the graph with x-axis, y-axis, x-ticks,y-ticks, legend and title your roll number and name.

Data :

Programming languages: Python, C++, Java, Perl, Scala, Lisp

Usage= 10,8,6,4,2,1

 

4.

x = np.arange(1,101)

y=np.random.randint(1, 101, size=100).tolist()

learn the two functions in numpy arrange(1,101) which will generate numbers 1,2,3,….,100 and radom.randint(1,100,size=100) which will generate 100 random between 1 and 100( both inclusive).

Use these x and y values to plot a scatter plot(popular plot for data analysis)

plt.scatter (x,y,size)  , where size is the size of dots used in plotting, change it with your roll number. Set the title with your name.

Graphical User Interfaces ( GUI)

Image
Most modern computer software employs a graphical user interface or GUI. A GUI displays text as well as small images (called icons) that represent objects such as directories, files of different types,command buttons, and drop-down menus. In addition to entering text at the keyboard, the user of a GUI can select an icon with a pointing device, such as a mouse, and move that icon around on the display. Commands can be activated by pressing the Enter key or Control keys, by pressing a command button, or by selecting a dropdown menu item with the mouse. Put more simply, a GUI displays all information, including text, graphically to its users, and allows them to manipulate this information directly with a pointing device. The structure of a GUI program differs significantly from that of a terminal-based program. Second, a GUI program is event driven, meaning that it is inactive until the user clicks a button or selects a menu option. In contrast, a terminal-based program maintains constant...

Turtle Graphics

Image
Graphics is the discipline that underlies the representation and display of geometric shapes in two- and three-dimensional space. Python comes with a large array of resources that support graphics operations.  A Turtle graphics toolkit provides a simple and enjoyable way to draw pictures in a window and gives you an opportunity to run several methods with an object.  Overview of Turtle Graphics Turtle graphics were originally developed as part of the children’s programming language Logo, created by Seymour Papert and his colleagues at MIT in the late 1960s. The name is intended to suggest a way to think about the drawing process. Imagine a turtle crawling on a piece of paper with a pen tied to its tail.Commands direct the turtle as it moves across the paper and tell it to lift or lower its tail, turn some number of degrees left or right, and move a specified distance.Whenever the tail is down, the pen drags along the paper, leaving a trail. In this manner, it is possible to pr...
