Excel charts let you illustrate your workbook data graphically to see trends. Also use charts in Excel to visualize comparisons.
By default, when you add more data to your spreadsheet, the chart may not include the new data. To fix this, you can adjust the data range. Simply click the chart, and it will highlight the data range in your spreadsheet. You can then click and drag the handle in the lower-right corner to change the data range.
If you frequently add more data to your spreadsheet, it may become tedious to update the data range. Luckily, there is an easier way. Simply format your source data as a table, then create a chart based on that table. When you add more data below the table, it will automatically be included in both the table and the chart, keeping everything consistent and up to date.
Watch the video below to learn how to use tables to keep charts up to date.
