fluctuate vs time. The time span I set is 1 hour. If I increase the time span, the line is still a straight one.
however, the exported data is right from data browser plot and fluctuate vs time.
I wonder what is wrong with my settings. The operation system is fedora25-64bit and CSS is unzipped from
I have attatched the plot in the attatchment. Thanks in advance.
