Re: Timechart - Same time range and span but diffe...

Hello,

i've put two timecharts on top of each other to compare their events by time. Both timecharts are using the same time range and span.

The top timechart has many data points whereas the bottom has just a few.

How can I show the same time range on the x-axis in both timecharts?

That is interesting because I recreated your inputs and charts (of course with different searches, but also timechart ones) and they seem to be working fine. I noticed however that you posted this on 30.09.2021 but have data from 1.10.2021 already. If you have data from the future, you might hit similar issue as https://community.splunk.com/t5/Splunk-Enterprise/help-on-basic-question-about-span-in-timechart/m-p...

Both timecharts are using a global time token (7d in this case) and span=1d.
I've expected, that both x-axis were matching.

Maybe it's what you tried to do, but they're definitely not sharing either the range nor the span.

1 day span produces a single value per day and your upper linechart has resolution of - i don't know - 1 hour?

So no, there's something wrong. We don't know what because we don't see the definitions.

What do you mean by "Both timecharts are using the same time range and span"?

The upper chart is definitely over a longer range (whole week, I think) than the lower one (this one covers less than a day).

It seem all to be correct.

But the charts haven't synchonous timelines.
