What is a Bar Chart?

A Bar Chart is a chart that uses horizontal or vertical bars to show us a comparative study about the various categories of the given data or information.

In other words, a Bar Chart shows/ displays and compares a discrete category of information provided. The height of each bar defines a specific numeric value. 

Types of Bar Charts-

1. Single or vertical Bar Chart-  A Single or Vertical Bar Chart is a graph that is used to convey the discrete value of the items for each category on either side of the axes on the graph. 
2. Horizontal Bar Charts- A Horizontal Bar Chart is similar to a Vertical Bar Chart but its position is horizontal. The longer the horizontal bar the more the category or value of the respective unit.
3. Grouped Bar Chart- A Grouped Bar Chart is a Cluster Bar Chart to depict discrete values for multiple items that lie under the same category. They also help us to show the values of sub-groups of similar categories. 
4. Stacked Bar Chart- Some Bar Charts have the bars of the graph divided into subparts that represent the discrete values for items that represent a portion of an entire group is called a Stacked Bar Chart.

These Charts are similar to Grouped Bar Charts only the Bar is divided into multiple sub-groups.

Stacked Bar Charts are also used to represent the percentage contribution that the different sub-groups contribute to each class.

Role of Bar Charts in the Stock Market

A Bar Chart in the Stock Market depicts the price bars of each stock or categories of stocks that show the movement of the prices of each stock over a brief period. Each bar has a straight (vertical) line that shows the highest price and lowest price reached by the stock during the wanted period.

Bar charts help the traders in the stock market to scrutinize trends, identify trends, and monitor the price movements.

If the upper and lower extremities of a Bar Chart in the field of the Stock Market are near to each other then the collateral will be considered immutable. If the price difference is large between upper extremities and lower extremities then collateral will be considered flexible.

If the opening price of the market is less than the current closing price then the bar chart will indicate as black or green. It will thus, represent a security benefit. However, the bar chart will display the loss of securities if the opening price of the market is near to the current market price. It will be displayed as red. 

Analysts post comparing several chart bars have found out that colour code indeed helps in understanding the graph quickly and easily.
