They make it very easy to represent values in a range of cells, by representing each value by a bar. A longer bar represents a higher value. They are like bars in a bar chart, except that they are contained in a cell. They can be of different colours and they can be shaded.
they are called error bars. It represents the amount of error associated with each data point
Color scales and data bars
Spreadsheet packages may chart one set of data in the form of a pie chart, or two or more sets of data in bar charts (with vertical bars, horizontal bars, or stacked bars), line charts, area charts, or mixed charts, which combine bars and lines

In a bar graph, the bars should not touch each other if they represent distinct categories, as this visually emphasizes that the categories are separate and discrete. However, in a histogram, which represents continuous data, the bars touch to indicate that the data falls within a continuous range. Thus, whether bars touch or not depends on the type of data being represented.
a bar graph
bar graphs are for measuring points of data.
The bars in a graph represent the data values for different categories or groups being compared. The height or length of each bar indicates the magnitude of the data for that category.
No. A title is for the overall chart. A legend will identify the bars and series on it.
Arrow bars in data visualization techniques are significant because they represent the range or uncertainty in the data being presented. They help convey the variability and potential error in the data, providing a more comprehensive understanding of the information being displayed.
