Which clause allows you to define which field is represented on the X axis of a chart?

In the context of charting in Splunk, the appropriate clause for defining which field represents the X axis of a chart is typically the "by" clause. This clause specifies how the data should be divided or categorized along the X axis in the visualization.

When creating a chart, the "by" clause allows users to designate a specific field to be visualized, ensuring that the representation is based on the intended data categories or values along the X axis. For instance, if you were creating a bar chart representing sales by region, you would use the "by" clause to indicate that the regions should be listed along the X axis.

The other options do not serve this purpose in defining the X axis. The "over" clause, for instance, is more about specifying how data is grouped or aggregated in relation to the Y axis rather than defining the X axis. "Time" is typically used when dealing with time-series data but does not directly correlate with the act of specifying an axis in a generalized chart. "From" generally refers to the source of data and does not pertain to axis definitions.

Understanding how to effectively use the "by" clause is essential for creating meaningful visualizations in Splunk, as it directly impacts how data
