How to split time equally in bar chart

[th1agarajan]

index=main sourcetype=myTest host="hello1234" getUserDetail | rex "(?im)^(?:[^:]*:){4}\s(?P<TIMESTAMP>(?P<Date>[^T]*)T(?P<Time>[^\-]*))-(?:[^,]*,){6}(?P<SERVICENAME>[^,]+),(?P<OPERATION>[^,]*),(?P<DURATION>[^(ms)]+)ms" | where DURATION >= 15000 | table DURATION,_time

I'm creating a bar chart from the above search. The problem I'm facing is

1. I am getting duration in x-axis and time in Y-axis. I need it in vice versa.
2. I have at least 500 results. Since the result count is more, timestamp value is disappearing. If the result count is around 25 then the timestamp values are visible. I don't want to show all timestamp values in x-axis. My requirement is i am creating report with one day's data. So I want x-axis to be split into 24 pieces (1 hr difference for each point). To make it clear

Time	Duration
10:10:00	50
10:12:00	150
10:15:00	500
11:10:00	250
11:30:00	510

I don't want five points in x-axis. I need only 2 points (10:00:00, 11:00:00). But i want all the points to be marked in chart. Is there a feature in Splunk to accomplish this?

You're probably looking for timechart:

... | timechart avg(DURATION)

That will automatically bucket your data into equally sized spans and put the time onto the X-axis.

In order to have 500 randomly distributed events fit a chart equally and have each and every event appear with its own column you'll need a huge number of columns - way beyond what you can reasonably chart or display.

I don't want to calculate average. i need all points to be plotted in chart(line chart). In Below search if the search results is < 10 I'm able to see the labels. But if the result is > 10 the label stars disappearing. I don't want to show all the time in x-axis. Just 12 points. i.e 00:00, 2:00, 4:00 ..

index=main sourcetype=myTest host="hello1234" getUserDetail | rex "(?im)^(?:[^:]:){4}\s(?P(?P[^T])T(?P[^-]))-(?:[^,],){6}(?P[^,]+),(?P[^,]*),(?P[^(ms)]+)ms" | where DURATION >= 10000 | sort -DURATION | chart list(DURATION) by _time

and you can define the spans for the (1hour) buckets by:

... | timechart span=1h avg(DURATION)
