Control Waveform Graph - Set Lower Limit and Autoscale Upper Limit

In a waveform graph is their a way to set the lower graph Y limit at zero and then have it autoscale the maximum Y limit as a percentage (150% for example) of the maximum Y graph value ?
Direction to examples or a starting point to read up on would be great !
Thanks,

Solved!

Turn off autoscale and set the max with a property node based on the array max of the data.

Disbaling No upper/lower bound value in a date range parameter

Hi folks,
When i added a new parameter with a date range , i can see two check boxes 'No lower value' and 'No upper value' along with 'include value' checkbox in the parameter dialog.
Is there any way to disable these check boxes?? If i cannot disable check boxes and when i select no lower value check box some random date value get returns to the query and the SQL query is giving no results and also i cannot set to a default lower and upper date range too.
Please help me in resolving this.
Thanks in advance.

These features are respective to the range component. If you do not need them, I would suggest that you use two date parameters. One date parameter can act as your low date parameter, and can have it's own default date. The other parameter can act as your high date parameter, and can have it's own default value.
The only change essentially, in the way the report runs, should be some minor changes to formulas, for example instead of having a selection criteria formula that says in {?DateRange}, you would now say >= {?StartDate} and <=

Capitalization doesn't work as described. One can start with lower case and change to upper, but changing from upper case to any of the other options doesn't work. Is there a way around this or is this just a glitch that needs fixing?

In Pages capitalization doesn't work as described. One can start with lower case and change to upper, but changing from upper case to any of the other options doesn't work. Is there a way around this or is this just a glitch that needs fixing?

I think it does work as described, but the description is not very complete. Capitalization does not change any of the characters that you type; what it does is allow some of the lower case characters to display as capitals. If you copy the result and paste it as plain text, you'll see that the lower case characters are still there. It doesn't actually say anywhere that it can make capitals display as lower case, and it can't.
The obvious way around this is to actually type what you want.
The more powerful way is to install WordService from Devon Technologies which adds the functionality of Pages' capitalization menu as well a lot of other ones. WordService actually changes the character to the one displayed, and it works in most of the applications on your Mac.

Lower bounds

Using generics for the first time I stumbled upon this basic situation:
ArrayList<Number> arrayList = new ArrayList<Integer>(); //compile error
Number number = arrayList.get(0);...then I found the correct syntax to make it work:
ArrayList<? extends Number> arrayList = new ArrayList<Integer>(); //correct
Number number = arrayList.get(0);...that because there is a lower bound feature and the "extends" and "super"keyworks is needed to differentiate between them:
ArrayList<? super Integer> arrayList = new ArrayList<Number>();
Object number = arrayList.get(0); //returns java.lang.Object...which has the same effect as:
ArrayList arrayList = new ArrayList();
Object number = arrayList.get(0);...which adds nothing compared to not using generics and making lower bouds almost useless.
Of course lower bounds add an extra check and this code doesn't compile:
ArrayList<? super Number> arrayList = new ArrayList<Integer>();
Object number = arrayList.get(0);...but does this kind of check has really any use?!
Its like wanting the following code to not compile:
Number number = new Integer(0);...but why would anyone want that?
Defining upper bounds is necessary to check types at compile-time and avoid NoSuchMethodError to be thrown, but I found no use to lower bounds besides hampering polymorphism and making the more useful upper bound syntax more polluted.
Maybe I didn't get the idea behind lower bounds... can anyone show me some real use to it?

...when you have 2 different generic classes and need to exchange data between then you must have a common upper and lower boundary. Got the idea... thanks.

Logistics Invoice verification MM - tolerances for lower limits and Credits

Hello,
My end-user is wondering why the system does not re-act/block on the lower limits of the price tolerance.
I have checked several SAP document and found:
1. Blocking Invoices
If a tolerance limit is exceeded, you receive a system message. You can post the invoice in the
system, but it is automatically blocked for payment if an upper tolerance limit is exceeded.
So for the lower tolerance limit there is no block only a warning.
2. Posting Credit Memos
The system does not check if your entries in the columns Amount and Quantity correspond to
the purchase order price or the invoice price.
So there is never a message or block for Credit Memos.
3. Subsequent Debits/Credits
If you want the system to carry out a price check for a subsequent debit, it compares the
value invoiced to date plus the value of the subsequent debit with the expected value based
on the purchase order. The system takes tolerance limits into account when carrying out the
price check. If a price variance exceeds one of the upper tolerance limits, the subsequent
debit is blocked for payment.
So only a check for subsequent Debit , not for Credit.
The examples my end-user has are the following.
1. Blocking Invoices
If the Invoice price is too low, the purchaser should be informed, he has to check what is wrong in the purchase order.
Maybe the price unit was filled in incorrectly or ...
Example:
a. Standard price is 100 Eur per 1 PC
b. Purchase price is 1000 Eur per 1 PC
Purchaser has made mistake it should have been 100 per 1 PC.
I checked and the Purchaser gets an info msg 06207 Effective price is 102.00 EUR, material price is 100.00 EUR,
but he can ignore this message.
c. Invoice price is 500 Eur per 1 PC
This invoice price is actually too high compared with the standard price but because of the high Purchase price no blocking occurs.
In this case we would like the system to also block the Invoice for payment.
2. Posting Credit Memos
Purchase order has a price of 1765 Eur.
We received goods and an Invoice for 1765 Eur.
We have returned the goods to the Vendor and we post a Credit Memo of 1048 Eur.
We receive no warning and the Credit Memo is not blocked for payment
The system should warn us that the Credit Memo has a too low value and we would prefer that the system blocks the Invoice.
3. Subsequent Debits/Credits
The Subsequent Credit can be seen as an Invoice price too low and therefore we would like it to be handled the same, see 1.
Can you please give us your opinion.
Is there a possibility to change the standard behavior of the system ?

Hello,
The limit check values have already been set up for key tolerance PP -upper and lower limit in OMR6 tcode.
Unfortunately when we are creating an invoice with a lower value than the expected value on the PO, it doesn't trigger the invoice block.
From what I've read on the forum SAP proposed as a solution the use of enhancement MM08R002-User exit for tolerance checks=> fm EXIT_SAPLKONT_002- Customer Exit: Change Tolerance Check, but in our system the check for upper limit is performed inside the fm MRM_AMOUNT_CHECK=>
fm MRM_TOLERANCE_CHECK
Überschreitung der Toleranzgrenze -
IF I_AKT_WERT > I_VERGLEICHSWERT.
... Betrag -
    IF T169G-XW2JA NE SPACE.
      DIFF_P = I_AKT_WERT - I_VERGLEICHSWERT.
      IF DIFF_P > WERT2.
        E_BETRAG = WERT2.
        E_RETURNCODE = 1.
        E_SPERRGRUND = 'X'.
      ENDIF.
    ENDIF.
Could you please advise me how you have implemented the check on lower limit tolerance?(eventually a sample of coding)
Thanks,
Andrei J.

My iphone won't switch on. I've tried holding the power and home button more than 30 seconds up to a few minutes but it didn't switch on and went straight to recovery mode. It died of a low battery and i already fully charged it i checked with my itunes.

i really need help here. I have only used my iphone for a month. my iphone won't switch on. it died of a low battery and i've already fully charged it and usually before it even fully charged, it will turn back on right but in my case nothing happened. i've tried holding the power and home button for 30 seconds and up to 2-3 minutes but no logo appear. it went straight to recovery mode. there's nothing wrong with my cable, i checked with itunes and this happened once a week ago but it did switch back on after i tried a few times but now it just won't switch on. i also have problems with my screen as there's some noises to the screen (i hope you get me) and when i turned the camera on, it was as if the whole screen is shaking. i'm currently studying in the middle east and there's no apple store here so i cannot use my warranty. i will only be back home in summer. please help me what should i do to at least switch my iphone on first.

I did a little bit of experimenting. I have an iPad original versions myself. I took it out of the box knowing that I haven used it in months and I expected the battery to be dead and sure enough the battery was as dead as I imagined it would be. For the first 30 minutes I experienced exactly what you are experiencing, but then the iPad suddenly powered up on its own (like it does when plugged into the charger) and I am using it now to type this response to you.
My point is that I am starting tothink that your battery has suddenly died on you for some reason or you have a hardware problem now. I would still try leaving the iPad charge for a while longer - maybe even overnight - and then try again in the morning. Unplug the iPad and try resetting with the home and sleep buttons. Try plugging the iPad in again. Unplug it, try restarting again. Let it charge for a while again.
After trying something like that, if it still will not start up, then I think it's time for a trip to an Apple Store and see what the Apple Techs think.

My ipod got very low battery and now won't connect with itunes?

My ipod got an extremely low battery and now it won't connect to itunes or charge when connected with the usb. I had not trouble connecting before this

Let it charge for awhile.
Does the iPod show that it is charging?
After charging for at least an hour try resetting the iPod. Also see:

Try the Hrad reset, especially must charge the battery for at least 2 hours.
After charging till full charge, at least 2 hours (preferably 4 hours)
Toggle the Hold switch, make sure you dont see the red mark when you do the next step
Reset the iPod -> Press Menu and Center button simultaneously for about 10 secs or till the Apple Logo comes ON
Then release the buttons

What does memory low mean and what can I do?

what does memory low mean and what can I do?

The iPad is low on RAM which is the memory that the operating system and apps need to run smoothly and efficiently. You can close apps and that might help. Restarting or rebooting the iPad might help as well.
To close you apps, tap the home button. Then tap the home button twice and the recents tray will appear at the bottom of the screen. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button twice.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Why is it that when I connect my iPhone 5S to my Windows Vista computer, the photos made with my iPhone are all of very low quality and most of them are turned upside down?

Why is it that when I connect my iPhone 5S to my Windows Vista computer, the photos made with my iPhone are all of very low quality and most of them are turned upside down?
On another note, the iPhone tells me that it's ''busy'' when opening a photo on the computer.
(I tried restarting my PC, connecting via another USB port, importing using PhotoStream, etc...)

Are you using the front or rear camera? When you say they are low quality, are you referring to file/pixel size, or how the picture looks? As far as upside down, how are you holding the phone? Older versions of Windows have issues reading the Metadata from the pictures and will not display the same.

My ipod 60gb classic is showing as fully charged until I connect it to my pc when it comes up with the error message, 'please wait very low battery' and the little wheel goes round and nothing happens, can anyone explain why this is and what i can do?

My ipod 60gb classic is showing as fully charged until I connect it to my pc when it comes up with the error message, 'please wait very low battery' and the little wheel goes round and nothing happens, can anyone explain why this is and what i can do?

I have worked my way through the assistant and nothing works. I have tried connecting in disc mode but although the screen on the ipod is showing that the device is charged and that it is in disc mode as soon as I connect it to the computer it comes up with the error message 'please wait very low battery' and stays like that until I disconnect when it appears to be OK again. I have tried on both pc and mac.
BTW the ipod is an ipod video not classic if that makes any difference.
Thanks

''Well When i plug in my ipod touch the battery life is low..i let it sit a wyhle.And it starts up to the apple logo and it stay there some time then it restartsback over to the very low battery and repeat(Over&Over)?

''Well When i plug in my ipod touch the battery life is low..i let it sit a wyhle.And it starts up to the apple logo and it stay there some time then it restartsback over to the very low battery and repeat(Over&Over)

Can you reset the device by holding the sleep and home button until the Apple logo comes back again?
If this does not work, try to connect in recovery mode, explained here: iOS: Unable to restore

Difference between Low level and Normal IMAQ ?

There are two options in IMAQ palette a low level and a normal one. Both have the same function names and the same icons the only difference being the balck and white icon of low level functions and colored icons of the normal functions. What is the difference between these two and what is the need of making a low level palette of functions ?

Low level imaq functions gives you relatively more function to control the hardware. Buffer functions is one which is not there on the high level palatte

I have an IPod 2nd generation I bought from a pawn shop. It worked for a day but now when I try to charge it, it keeps switching back and forth from the large full screen icon of a low battery and a lighting bolt below to the blue screen with the apple symbol in the middle. I had it on charge all night but still dead.
