a. Legend: A legend is a key to understanding the data displayed in a chart. It is a small box, usually placed at the side or bottom of a chart, that explains what the different colors, symbols, or patterns used in the chart represent.

b. Chart Area: The chart area encompasses everything within the chart window, including all data, chart elements, such as titles, labels, and legends, and the plot area itself. It is the total area that contains the entire graphic representation of your data.

c. Data Series: A data series is a set of related data points or values that are plotted on a chart. Each data series in a chart has a unique color or pattern and is represented in the chart legend. In a bar chart, for example, each bar is a single data point from a data series.
