3 Seemingly Important Limitations of TIA Portal Advance V11 Trendview

I find at least four important problems on the TIA Portal Advance V11 Normal Trendview:

1) It cannot allow Historical graph while accommodating real-time changes. The Historical Trend and the Real-time Trend are distinguished. This is important because both are highly relevant for the process (the Historical Trend for process value analysis and the Real-Time Trend for PID response analysis). At worst, you have to configure two Trendviews per process value.

2)I cannot zoom in into a certain Y value, but only, and still very limited, in time (X axis). I need this because I have some very high ranged Y values, and I cannot monitor the small scale oscillations of it.

3) Using it as a Historical Trend, I cannot go back into a certain X value (time), only few minutes back via the trendview toolbarbutton. I need this because I want to go back and see my trend, perhaps hours or evendays before, which will not be viable using the minute-back button.

*4) It has not so good appearance!

Perhaps these are not really limitations, but just an indicator of my lack of knowledge. And I hope it's the latter so that, by your help, there will still be possible solutions to these problems.

Now, does the f(x) trendview also suffer from this seeming problems? If not, then, if I can use the f(x) trend to function as a normal trendview (X-Axis=time), then, this would be a good solution to all this 4 problems above!

------------------------------------------------------------

P.S. : *You can just ignore problem #4!

Thanks for any response!

Is that from TIA Portal Advance V11? It seems not. And that's not how my Trendview looks like, mine lacks those relevant toolbar buttons you just have mentioned.

What's your software version?

It makes me feel bad that Siemens has to divide even the important functionalities by software version. I understand if it is the scale/capacity of application, or even the appearance that would be absent on the low version like mine, but the relevant and common functionalities.. Hmm..

But as Tweety have said, perhaps it is available on V12. But it's no way a solution for my case!

Anyways, thanks much!
