Explain the different components of a chart.

The different components of a chart are:

1. Chart Area — Chart area includes all the area and objects in the chart.
2. Category Axis — Category axis or X-axis is the horizontal axis of a chart.
3. Value Axis — Value axis or Y-axis is the vertical axis used to plot the values. It is located at the left side.
4. Data Series — Data series are the bars, slices or other elements that show the data values. If there are multiple data series in the chart, each will have a different colour or style.
5. Category Name — Category names are the labels, which are displayed on the X and Y-axis.
6. Plot Area — Plot area is a window within the Chart area. It contains the actual chart itself, and includes plotted data, data series, category, and value axis.
7. Legend — It depicts the colours, patterns or symbols assigned to the data series. It helps to differentiate the data.
8. Chart Title — It describes the aim and contents of the chart.
9. Gridlines — These can either be Horizontal or Vertical lines depending on the selected chart type. They extend across the plot area of the chart. Gridlines make it easier to read and understand the values.
