Create time-based charts
Use the timechart reporting command to create useful charts that display statistical trends over time, with time plotted on the x-axis of the chart. You can optionally split data by another field, meaning that each distinct value of the "split by" field is a separate series in the chart. Typically these reports are formatted as line or area charts, but they can also be column charts.
For example, this report uses internal Splunk log data to visualize the average indexing thruput (indexing kbps) of Splunk processes over time, broken out by processor:
index=_internal "group=thruput" | timechart avg(instantaneous_eps) by processor
