To help you analyze the data that is displayed in a chart, you can add predefined lines or bars (such as series lines, drop lines, high-low lines, and up-down bars) to specific charts (such as 2-D stacked bar and column charts, line charts, pie of pie and bar of pie charts, area charts, and stock charts). If you no longer want to display the lines or bars, you can remove them.

Predefined line and bar types that you can add to a chart
Specific line and bar types are available in 2-D stacked bar and column charts, line charts, pie of pie and bar of pie charts, area charts, and stock charts. Depending on the chart type that you use, you can add one of the following lines or bars:
- Drop lines Available in 2-D and 3-D area and line charts, these lines extend from data points (data points: Individual values plotted in a chart and represented by bars, columns, lines, pie or doughnut slices, dots, and various other shapes called data markers. Data markers of the same color constitute a data series.) to the horizontal (category) axis to help clarify where one data marker (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.) ends and the next data marker starts.
- High-low lines Available in 2-D line charts and displayed by default in stock charts, high-low lines extend from the highest value to the lowest value in each category.
- Up-down bars Useful in line charts with multiple data series, up-down bars indicate the difference between data points in the first data series and the last data series. By default, these bars are also added to stock charts, such as Open-High-Low-Close and Volume-Open-High-Low-Close.
