OF CSE, AUDISANKARA INSTITUTE OF TECHNOLOGY, GUDURU. 4 Graphical Analysis is a tool for science students to collect, graph, and analyze data. The primary advantages of graphical representation of data are: Facilitates and improves learning: graphics make data easy to understand and eliminate language and literacy barriers. Understanding content: visuals are more effective than text in human understanding.

Each point represents the values of two variables. One variable is chosen in the horizontal axis and another in the vertical axis. The simple scatterplot is created using the plot() function.

OF CSE, AUDISANKARA INSTITUTE OF TECHNOLOGY, GUDURU. 12 A line chart is a graph that connects a series of points by drawing line segments between them. These points are ordered in one of their coordinate (usually the x-coordinate) value. Line charts are usually used in identifying the trends in data. The plot() function in R is used to create the line graph

- 14. PIE CHARTS 2/20/2021 VIKRAM NEERUGATTI, PROF. & HOD, DEPT. OF CSE, AUDISANKARA INSTITUTE OF TECHNOLOGY, GUDURU. 14 R Programming language has numerous libraries to create charts and graphs. A pie-chart is a representation of values as slices of a circle with different colors. The slices are labeled and the numbers corresponding to each slice is also represented in the chart. In R the pie chart is created using the pie() function which takes positive numbers as a vector input. The additional parameters are used to control labels, color, title etc

OF CSE, AUDISANKARA INSTITUTE OF TECHNOLOGY, GUDURU. 20 A bar chart represents data in rectangular bars with length of the bar proportional to the value of the variable. R uses the function barplot() to create bar charts. R can draw both vertical and Horizontal bars in the bar chart. In bar chart each of the bars can be given different colors

Additional argument indicating the width and the height of the image can be also used. Create the plot.
