question about x-axis presentation with rostopic data

[sizsJEon]

Problem description

Is there a way to display the units on the x-axis as data seq or numbers since input, rather than the current time?

In many screenshots in plotjuggler, I see samlll numbers in x-axis, but in my case it's always the current time like below.

(There is an inconvenience in that the data on the x-axis is expressed in the form of YYYYMMDD HHMMSS.0.

I am experiencing this problem with ros topics such as Jotstick topic, imu topic, float64multiarray, etc.

Steps to reproduce (important)

Ubuntu 20.04, ros noetic
