TrendView Feature Suggestion/Request
« on: April 29, 2016, 12:16:27 PM »
While auto-ranging the Y axis is a feature, I have noticed that most programs that offer it have a tendency to pick really unusual increments for the major lines. I have a bit of trouble figuring out what values I am seeing when the increments are not some "standard".

I would like to see an option to force the major lines to set themselves to useful increments. If the values cross zero, I want to see a zero line. And increments of 5, 10, 25, 50, 100 e.g. on either side rather than -16.666, +33.333 type stuff that was maybe easy to code, but harder to decipher.

I am not asking for the already present manual settings, because I use those, but they are not always ideal either due to missing the range I needed to cover. I just want to see increments that are easier to judge by eye. On the manual ranges it would be cool to be able to get suggestions from the software on major minor ticks based on user desired increments.

The time axis could also benefit from logical number lines vertically.

Oh, while I am asking, can the vertical line that we see just before we click on the trend to see the values maybe stay on the screen until we pick another spot? I usually forget exactly where I clicked if I don't write it down to the mS and the time difference I need to check can be rather small.

OOH OOH, I just thought of another! How about a table that gets populated by the values 1) where we click and 2) at each click? Exportable as Excel or CSV would be really cool. And when we save/export it it can ask us if we want to open it like Export Memory Data does.  8)

That's it! I'm done (for now.)

BobO's trend here http://forum.hosteng.com/index.php?action=dlattach;topic=1768.0;attach=1096;image is what prompted this, though a temperature trend from some other software looks similar on increments selected.

Concur 100% on this.  I hate when auto-scaling (and a lot of PLC's and HMI's do this) comes up with furlongs or fortnights or some random thing as a major division increment.
I retract my earlier statement that half of all politicians are crooks.  Half of all politicians are NOT crooks.  There.
