Concerning Splunk, the time chart command is utilized in generating a chart that shows the supply of data over time. Moreover, the chart generated by the time chart command is a bar chart that shows the occurrence of events for every time interval. To efficiently use the timechart command, it’s significant to understand the time axis plus the way it represents time in Splunk. Let’s find out the time axis in Splunk plus its representation when utilizing the time chart command.
Understanding Time Axis in Splunk
In Splunk, the time axis is the x-axis in the chart which represents time. The time axis shows the time intervals in which the data is aggregated. In Splunk, the time axis is auto-generated depending on the time range chosen for the chart.
Specifying Time Interval for Time Axis
When utilizing the timechart command, one can specify a time interval for the time axis utilizing the bin command. This enables one to specify the length of time intervals in minutes, seconds, hours, or days. For instance, if you need to generate a chart with time intervals of five minutes, you will utilize the syntax below:
timechart span=5m count
Time Ranges for Time Axis
Apart from specifying the time interval, one could also state the time range for the chart utilizing the time command. Time command enables one to specify the start & end time for a chart. For instance, if you need to generate a chart within 24 hours, one would utilize the syntax below.
timechart span=5m count over 24h
Showing the Time Axis in a Customized Format
The time axis in Splunk is auto-shown in a standard format. That is YYYY-MM-DD HH:MM:SS. Moreover, you can modify the format of the time axis with the help of the timeformat command. The Timeformat command enables one to state the format for the time axis utilizing strftime codes. For instance, if you need to show the time axis in a MM/DD/YYYY format, you would need to use the syntax below.
timechart span=5m count over 24h timeformat=”%m/%d/%Y”

Understanding Time Granularity of Time Axis
The time granularity of the time axis is determined by the least unit of time explained in the time format command. For instance, if the time format is stated as “%Y-%m-%d”, time granularity is at the day level. If the time format is defined as “%Y-%m-%d %H:%M”, the time granularity will be at a minute level. The time granularity shows the smallest unit of time which can be displayed on a time axis.
Conclusion
The time axis in Splunk shows time & displays time intervals for which the information is being aggregated. When utilizing the time chart command, one could specify the time interval plus time range for the time axis, and also show the time axis in a customized format. Getting to know the time axis plus its representation when utilizing the time chart command is significant to efficiently generate charts that show the distribution of data over time.
