What are the types of charts in statistics
The term “chart” is derived from Latin word ‘carta’ which means an outline or a paper sheet and most people believe that it is used frequently with graphs. One type of chart that is commonly used to visualize information is the bar chart. It has three main parts — one represents numerical values, another is a visual representation of numbers, and the third part is to indicate the relationship. We can divide any data into two categories by using different colors — red and green, blue and purple. It also has a horizontal line to show relationships between the variables, by showing percentage change.
Bar Chart
A bar graph, or bar chart is one of the widely used kinds of charts for analyzing data. A bar chart can be defined as the plot of points on a vertical axis, along which the size of each point is represented, and its color is changed based on some condition like sales increase, price hike, etc. The bar chart is one of the simplest graphs to understand because each variable is represented in percentage form:
Properties of Bar Graph
The property of bar chart consists of x-axis and y-axis, and it has many characteristics to be seen. These include (a) the bars represent continuous value for a given interval, (b) the bars indicate a trend, (c) the bars indicate a range. They have 4 different kinds of bars: normal bars, left and right bars, top and bottom bars, and they can also be categorized further by their area, height, width, and location of borders. Each bar shows a single parameter as the axes. For example, if we have to examine how many books read by the students, this bar chart will help us figure out the number of books read by the number of students. So we need to interpret in detail. To do so, let’s see the below example to get a better understanding about what’s going on in it.

In above graph the X-axis represents the number of books read by students. On the Y-axis we can see the number of students. However, in order to make meaningful conclusions, we should discuss the whole picture: how many students read such books? That is the crux of most of our answers. Now let’s try a more interesting exercise, which we call profitability bar graph:

The profitability bar chart contains only the above-mentioned properties i.e., both the X-axis and the y-axis.
