If you insert a chart from a file or pasted data, you won't need to make too many data changes to your chart. If you add a new chart, you’ll need to add more data. There are several ways to do this.

You can show data labels in a variety of formats by using the Data menu button in the Labels group of the Chart tab. If you choose to show data labels, you can click those labels and type in new values. The chart will automatically adjust to reflect the change.

When you select a series, black square handles appear on it. You can drag these handles to change the data value as well.

If you’d rather work with a table, click the
at the bottom right
of your chart, or click Show Data Table in the Chart tab, to show the data table corresponding to
your chart. Any changes made in the table are immediately reflected in the chart, and vice versa.
