Let's address each of the statements one by one:
We cannot create Bar chart in Excel 2016.
This statement is false. You can create a Bar chart in Excel 2016. To do this, you typically select the data you want to visualize, then go to the "Insert" tab, and choose the "Bar Chart" option from the Chart group. Excel provides several types of bar charts, such as clustered, stacked, and 100% stacked bars.
Excel does not provide any tool to improve the appearance of a chart.
This statement is also false. Excel has many features to enhance the appearance of charts. Once a chart is created, you can use the Chart Tools, which include the Design and Format tabs. These allow you to change the chart type, add chart elements like titles and data labels, and apply various styles and color schemes. You can also format individual chart elements like the background and axes.
Plot area of a chart is the rectangular area bounded by the two axis.
This statement is true. The plot area is indeed the rectangular area where the graphical representation of the data is drawn. It is bounded by the x-axis and y-axis in most cases, and it is where the data points, lines, bars, etc., appear.
The bar chart displays the data in the form of long rectangular rods also called bars.
This statement is true. Bar charts are a type of graph that represents data with rectangular bars, where the length of each bar is proportional to the value it represents. The bars can be displayed either vertically or horizontally depending on the type of bar chart used.
These explanations provide a basic understanding of how Excel works with bar charts and how the appearance of charts can be improved using the available tools in Excel.
