Computer Basics -11 || Using Charts in place of Data Tables in Excel.

Charts are the graphical representation of the data. Using Charts in place of Data Tables are more realistic than tables or any other mode of presenting data.

This is a very attractive feature of Excel, which is used by each professional to create their presentations, reports, data collection, etc.

Note: A table should have at least two data columns to generate any type of chart.

Benefits of Charts

Instead of showing data in tables we could use charts. Below are the basic features of Charts:

1. Easy to use and apply charts on any existing data table.
2. Customization of charts is very easy and doesn’t impact the original data.
3. Presenting data in a chart over a table is more powerful. Best way to convey information to the audience with references.
4. One table multiple presentations. It means any number of the chart can be generated using a single data table.
5. Multiple types of charts available like Column, line, pie, bar chart, etc.

Properties of Charts

There are some important information or properties of charts which have been used to convey the information or present the information more accurately. It makes the data more understandable to the audiences.

1. Chart Type: Correct chart type should be used to convey the relevant information.
2. Chart Title: Chart title should be crystal and clear to make understand viewers the objective to chart.
3. Axis values/Data: Data values will appear in horizontal-axis or vertical-axis.
4. Axis Titles: Short description of the data appearing on the axis.
5. Series: Presentation of data on the Chart. We can change the color of each series in the chart.
6. Legends: As mentioned in the above point, we can change the color of each series in the chart. Legends are the color notation and name to identify the individual series.
7. Data Labels: Data label used to show the value of each series on the chart.
8. Select Data: To add/remove values of any row or column from the Chart, without impacting the original table.
