By default, how does Excel plot the x-axis for a graph?

When Excel creates a graph, it typically organizes the x-axis based on the layout of the data within the spreadsheet, specifically considering the number of rows in the data set. Each row often corresponds to a different data point or entry, and Excel will automatically plot these points along the x-axis, representing their sequence or corresponding category.

This method of plotting helps ensure that each data point is represented clearly and accurately along the x-axis, allowing users to visualize the relationship between the data points effectively. By establishing the x-axis based on rows, Excel maintains a consistent and intuitive approach to data representation, which is especially useful for time series or categorical data.
