Excel charts let you illustrate your workbook data graphically to see trends. Also use charts in Excel to visualize comparisons.
There are many other ways to customize and organize your charts. For example, Excel allows you to rearrange a chart's data, change the chart type, and even move the chart to a different location in a workbook.
Sometimes you may want to change the way charts group your data. For example, in the chart below Book Sales data is grouped by genre, with columns for each month. However, we could switch the rows and columns so the chart will group the data by month, with columns for each genre. In both cases, the chart contains the same data—it's just organized differently.
If you find that your data isn't well suited to a certain chart, it's easy to switch to a new chart type. In our example, we'll change our chart from a column chart to a line chart.
Whenever you insert a new chart, it will appear as an object on the same worksheet that contains its source data. Alternatively, you can move the chart to a new worksheet to help keep your data organized.
