I am sorry if this is suggested before. I did a quick search but didn't find earlier suggestions. However it would be useful to have two or more user-definable timescales. You could then see the last hour in the right side of the screen and for example the last week in the left side. It is nice to see at one glance what is happening now and what has happened during the last days.
Also I thing that the vertical scale could be optionally logarithmic. Then you would see the millisecond variations and the high peaks at the same time.
What do you think Pete? Helmer
