The correct answer is option 4- All of these.
All of these are elements of graphs/chart.
A chart/graph are a pictorial presentation of data. The chart/graph elements are as follows-
- The chart area: The entire chart including all elements.
- The plot area: In a 2-D chart, the area is bounded by the X and Y axes. In a 3-D chart, the area is bounded by the three (X, Y and Z) axes.
- The data points: Individual values plotted in a chart and represented by bars, columns, lines, pie or various other shapes are called data markers. Data markers of the same colour constitute a data series. The data series are related data points that are plotted in the chart/ graph. Each data series in a chart is shown in a unique colour or pattern or both. Its identification is given by the legend. There may be more than one data series in a chart/graph.
- The horizontal (category) and vertical (value) axis: The x-axis is usually the horizontal line which contains categories (independent values or categories) and y-axis is usually the verticals which contains data (dependent values).
- The legend: It is an identifier of a piece of information shown in the chart/graph. The legends are assigned to the data series or different categories in a chart.
- A chart and axes titles: Descriptive text for chart title and axis title.
- A data label: This provides additional information about a data marker to identify the details of data point in a data series.
Some of the elements are displayed by default when we prepare the chart/graph; others can be added as needed. It is also possible to change the format or display of the chart/graph as desired. |
