On a chart, such as a line chart, a data markers shows where the point is, usually done with a dot or a box or a cross. A data label will show the actual value of that data point. So on a line chart you might see a data marker on the line to indicate it is a value from the data and with it a data label will tell you what the actual value is.
Data Point
A label helps you to identify the data series quickly (data series: Related data points that are plotted in a chart. Each data series in a chart has a unique color or pattern and is represented in the chart legend. You can plot one or more data series in a chart. Pie charts have only one data series.), you can add data labels (data label: A label that provides additional information about a data marker, which represents a single data point or value that originates from a worksheet cell.) to the data markers (data marker: A bar, area, dot, slice, or other symbol in a chart that represents a single data point or value that originates from a worksheet cell. Related data markers in a chart constitute a data series.) in a chart. To update data labels with changes that you make to corresponding data in the worksheet, or to display the text or numbers in worksheet cells in the data labels, you can link data labels to worksheet cells. If you no longer need data labels, you can remove them.
