Excel charts let you illustrate your workbook data graphically to see trends. Learn how to edit charts in Excel in this free lesson.
When you add a chart to your worksheet, Excel creates a link between the chart and your source data. This way, any changes you make to the original source data are instantly reflected in your chart.
You can also add rows or columns of data to an existing chart by selecting Add Data on the Chart menu.
Your chart should update to display the new data.
