Which of the following can you change on a graph that has already been created?

In a graph that has already been created, you have the flexibility to make various adjustments to enhance clarity and presentation. All elements related to the axes can typically be changed:

• Axis labels can be modified to provide clearer descriptions of what each axis represents, which is particularly important if additional information is required to make the graph understandable.
• Axis lines can be altered in terms of style, color, or thickness for better visual distinction or emphasis on certain data points.
• The axis scale can also be adjusted, allowing you to change the range of values displayed. This is crucial for zooming in on a particular data range or expanding the view to include more context.

Making these changes is essential for accurately conveying the data's insights and for ensuring that the graph communicates effectively to its intended audience. Therefore, the ability to change all these features—labels, lines, and scale—demonstrates the versatility and adaptability necessary for data visualization in decision-making processes.
