Slow Zoom In/Out in XY Graph

I am experiencing very slow zoom in/zoom out in XY Graph. Each action takes roughly 5 seconds. Is this normal?
The anti-aliased is not On. I am not using dash lines.
Can someone shed some light here?

As an approxmation use the number of points plotted equal to the number of pixels in the width of the plot area (for a line plot). If you feed the graph more points than it has pixels to display them, the code internal to the graph has to manipulate that data to determine where to place each pixel. When you drop a new XY graph on the front panel it has 250x250 pixels. When I stretched one to fill my screen I had 1580x862. So X-axis arrays larger than a few hundred to about two thousand elements will result in some data manipulation by the graph.

Just a suspicion: Adobe is adding more and more compute-intensive functionality in the newer versions - for example image analysis that affects the way the PV2012 controls work - in anticipation of more and more powerful computers. It's the normal way of things.
PV2012 seems to take about twice as long for me to complete a conversion than its predecessor. But on my reasonably powerful computer that's the difference between 2 and 4 seconds - no problem, really.
I'm not sensing any difference in zoom speed.
everytime i load a canon raw file , it 's always to 2012!
what 's wrong?
I don't know. Photoshop CS5 comes up with PV2010 for me for images I haven't opened before, because that's what I saved my Camera Raw Defaults as. I don't use the camera serial number/ISO specificity settings though.
Are you thinking of updating to Photoshop CS6? I mention this because the released version is available today.

Zooming out stepwise in graph

When zooming in a Labview graph control several times I would like to unzoom in the same steps I zoomed in, eg if I zoom-in in 3 steps I want to zoom out in 3 steps.The built-in unzoom only zooms out to maximum scale, so I guess this has to be done programatically. Has anybody tried this and can provide me with an example in LV 7.1?

Check out the attached. 'Begin time' and 'End time' are user controls; the user can zoom
with either the normal graph control or by manually entering times into the tstamp controls.
'Undo zoom' works back through the queue.
Hope this helps.

Slow zoom failure in Spaces

Ok, this one is hard to describe, but I'll try. I switch spaces a lot, using the center button of my mouse. This is invaluable when working in Eclipse and having multiple Safari windows open (I just can't seem to remember the details of all those Java libraries!).
From time to time, when switching spaces, I will select the new space. Instead of the new space zooming to the foreground quickly, the selected space will zoom very slowly (I'm running a quad core Mac pro with 5GB so no, it's not the machine). Once it completes this slow zoom, the space will suddenly disappear in favor of a space I didn't select. It's really irritating when you are in a hurry to figure something out or are trying to keep your concentration on a piece of half-written code.
Has anyone else seen this behavior? Does anyone have an explanation or theory as to what might be happening to Spaces? The error doesn't seem to be harmful in any way. But it does represent about the only 'irritating' post 10.5.2 bug I know of on the Mac Pro.
Thanks,

Has anyone read this post? Or is it such a stupid question, there's no use in replying to it?

IMac CPU3.06 GHz Intel Core 2 Duo, 8GB, Extremely slow and repeatedly "out of Memory" since migration from Mountain Lion to Mavericks

Dear Apple Support Community.
As mentioned by a number of users reporting the same problem, my 2009 iMac CPU3.06 GHz Intel Core 2 Duo, 8GB RAM, has become extremely slow and repeatedly "out of Memory" since it was migrated from Mountain Lion to Mavericks (OS 10.9 then OS 10.9.1).
I have already run CleanMyMac, deleted 5GB of useless stuffs, which did not translate into any improvement. Following the advices collected in other Apple Support Community threads, I have applied EtreCheck the outcome of which is provided below.
For information, I have also upgraded my 2011 MacBook CPU2.3 GHz Core i7, 8GB which became only a bit slower than before, sometimes freezing which it almost never did before. However, I am used to the fact that Mac get usually slower and more prompt fo freeze after upgrading to a more recent OS.
Both my 2009 iMac and my 2011 MacBook have F-Secure installed. So the problem with the 2009 IMac is unlikly to be due to the presence of F-Secure. Interestingly, the few abnormalities found by Etrecheck were exacly identical before I ran CleanMyMac. There are two more findings (mentioned below) since I ran CleanMyMac on the 2009 iMac, which again didn't improve the problem.
So please find below the details of the EtreCheck experience and some additional measurements made with iStat while running EtreCheck:

Please find now some additional measurements collected with iStat while running EtreCheck:
Practically:
The iMac can work slowly with only one software e.g. either Mail or Safari or Firefox, but still the below "out of Memory" message occurs about every 3 minutes.
Aperture has becomre to slow to be useable
If trying to write a mail (with Mail) while Safari or Firefox is open, then the "out of Memory" message occurs about every 20 seconds so I need to check on "Resume" several times per minute.
Conclusions
From the above, unless anyone in the Apple Support Community proves to be able to identify a specific problem leading to a way to find a cure, I tend to conclude that Mavericks is not suitable for computers operating with a Core 2 Duo CPU even with a 8GB of RAM.
Unless I missed something, I did not see any warning from Apple Computer Inc. informing their customers they should refrain from upgrading Core 2 Duo Computers.
The only solution I see so far is to downgrade from Mavericks to Mountain Lion. And the Apple Support Community would confirm that it is the only solution, I would appreciate to get your guidance on how to proceed.
Intended action plan
Migrate the above 2009 iMac to a 2014 Mac Mini Server operating on Mavericks to ensure that no data may be lost while downgrading to Montain Lion.
Provided the above downgrading operation is successful, assign this 2009 iMac to partial retirement e.g. Mail, Skype, iTunes and DVD player.
In advance, I would like to thank the Apple Community for helping me either i) finding a cure to the problem, ii) or confirming that Mavericks cannot operate properly on Core 2 Duo computers, iii) and in such a case, guiding me on how to downgrade to Mountain Lion.
Yours sincerely
Core

... what anti-virus would you recommend using?
Use what is already included with OS X. It already includes everything it needs to protect itself from viruses and malware. Keep it that way with software updates from Apple.
A much better question is "how should I protect my Mac":
Never install any product that claims to "speed up", "clean up", "optimize", or "accelerate" your Mac. Without exception, they will do the opposite.
Never install pirated or "cracked" software, software obtained from dubious websites, or other questionable sources. Illegally obtained software is almost certain to contain malware.
Don’t supply your password in response to a popup window requesting it, unless you know what it is and the reason your credentials are required.
Don’t open email attachments from email addresses that you do not recognize, or click links contained in an email:
Most of these are scams that direct you to fraudulent sites that attempt to convince you to disclose personal information.
Such "phishing" attempts are the 21st century equivalent of a social exploit that has existed since the dawn of civilization. Don’t fall for it.
Apple will never ask you to reveal personal information in an email. If you receive an unexpected email from Apple saying your account will be closed unless you take immediate action, just ignore it. If your iTunes or App Store account becomes disabled for valid reasons, you will know when you try to buy something or log in to this support site, and are unable to.
Don’t install browser extensions unless you understand their purpose. Go to the Safari menu > Preferences > Extensions. If you see any extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone.
Don’t install Java unless you are certain that you need it:
Java, a non-Apple product, is a potential vector for malware. If you are required to use Java, be mindful of that possibility.
Disable Java in Safari > Preferences > Security.
Despite its name JavaScript is unrelated to Java. No malware can infect your Mac through JavaScript. It’s OK to leave it enabled.
Block browser popups: Safari menu > Preferences > Security > and check "Block popup windows":
Popup windows are useful and required for some websites, but popups have devolved to become a common means to deliver targeted advertising that you probably do not want.
Popups themselves cannot infect your Mac, but many contain resource-hungry code that will slow down Internet browsing.
If you ever see a popup indicating it detected registry errors, that your Mac is infected with some ick, or that you won some prize, it is 100% fraudulent. Ignore it.
Ignore hyperventilating popular media outlets that thrive by promoting fear and discord with entertainment products arrogantly presented as "news". Learn what real threats actually exist and how to arm yourself against them:
The most serious threat to your data security is phishing. To date, most of these attempts have been pathetic and are easily recognized, but that is likely to change in the future as criminals become more clever.
OS X viruses do not exist, but intentionally malicious or poorly written code, created by either nefarious or inept individuals, is nothing new.
Never install something without first knowing what it is, what it does, how it works, and how to get rid of it when you don’t want it any more.
If you elect to use "anti-virus" software, familiarize yourself with its limitations and potential to cause adverse effects, and apply the principle immediately preceding this one.
Most such utilities will only slow down and destabilize your Mac while they look for viruses that do not exist, conveying no benefit whatsoever - other than to make you "feel good" about security, when you should actually be exercising sound judgment, derived from accurate knowledge, based on verifiable facts.
Do install updates from Apple as they become available. No one knows more about Macs and how to protect them than the company that builds them.
Summary: Use common sense and caution when you use your Mac, just like you would in any social context. There is no product, utility, or magic talisman that can protect you from all the evils of mankind.

Adobe illustrator CC Zoom in & out problem

Hi,
I am facing an issue right now..
When i open a large AI file that above 1GB, then i zoom in & out .. the design will go out of form.
However, when i open small file like 400+ MB, no issue on zoom in & out.
I really no idea for this issue..
Here is my PC spec,
Windows 8.1 Professional
3.40 gigahertz Intel Core i7
32GB RAM
NVIDIA GeForce GTX 650
TQ.

Moving this discussion to the Illustrator forum.
Wandasgirl I would recommend reviewing your installation logs for errors. Please see Troubleshoot install issues with log files | CC - http://helpx.adobe.com/creative-cloud/kb/troubleshoot-install-logs-cc.html for information on how to locate and interpret your installation log files. You are welcome to post any errors you discover to this discussion.

Alt & scroll wheel not working on Photoshop CC to zoom in / out

Hey! So i'm using the latest version of Photoshop CC, and i'm also running the Technical Preview of Windows 10. So In Photshop, usually when you hold the alt key and scroll with the scroll wheel on your mouse, it will zoom in / out of the image on Photoshop. Well i'm having some problems with that, it isn't working at all. In preferences I have it set to zoom with scroll wheel. Anyone know why it isn't working? Could it be something with the Windows 10 Preview?

Please report Windows 10 issues to Microsoft, so they can get the information they need to fix the OS bugs before shipping the final version.

SAP SNC Portal DCM screen performance is very slow and times out

Friends,
SAP SNC Portal DCM screen performance is very slow and times out when user trying to pull data using customer location
What are the cleanup activites we can do to improve the overall SNC performance ?
We did open OSS message but so far no reply from SAP , Is there any one faced performance issue ?
User/vendor is complaining about slowness , query is standard SAP and its taking more time .(table - /LIME/NTREE) , It looks like number of data are huge causing this problem related to LIME/NTREE table. What are the options to improve the performance ?
Thanks in Advance
Hanuman Choudhary

hi Team,
Pls . note the advise from SAP below, IS there any have experiance of archiveing /LIME records ?
Please advise how to start & what the steps in archiving ?
Thanks in advance
I had a look at the DCM query performance in PH1 system and figured out
that most of the time is spent at the LIME layer of database. The
following LIME tables are having far too many entries and is causing
the bottleneck during the query execution.
/LIME/NLOG_QUAN - 38,165,467
/LIME/PN_ITEM - 19,116,518
/LIME/PN_ITEM_TB - 19,154,124
These tables are storing the historical information about LIME(stock)
updates. Since these table grow with each change/update of stock
information, it will slow down the performance of the system over a
period of time. And to avoid the slow responses, the tables should
ideally be archived on a periodic basis to keep the data volume as
minimal as possible. You may have to discuss with the Business to
determine the number of days of LIME record you would want to retain
in the system. I would strongly recommend you to consider the LIME
archival retaining the minimum days (<=60 days) of historical
information. You can find more information about the Lime Archival
in the Sap Help link:
http://help.sap.com/saphelp_scm2007/helpdata/en/44/2a83121dde23d1e10000000a1553f7/frameset.htm.
Kindly get in touch with your BASIS consultant for the LIME archival.
The application performance should definitely improve after the LIME
archival. Please do not hesitate to get in touch with me in case you
require any further clarification in this regards.
Best Regards

Sometimes when panning with the hand tool, it zooms way out instead of just moving the canvas

So normally when you hold the space key and drag, it just moves the canvas, but every now and then, seemingly randomly, it zooms way out and shows a little box which is the size and shape of the area of canvas I was previously looking at. If I move the box and let go of space, it zooms to that location, but all I wanted was to move normally. I don't think I've ever wanted the zoom out, move, then zoom back in behavior. What causes that? How do I make it stop?

It's "bird's eye view" and by coincidence, your problem was discussed in another thread last night: Problem with zoom in Photoshop CS6

I am unable to zoom in/out using the touch pad; yesterday i could zoom in/out of website pages, pics, etc, now today it is not letting me; how do i fix this?

T510: TouchPad no longer allowing for zoom in/out

My TouchPad is all the sudden no longer allowing for zoom in/out. How do I restore that function.
Moderator Note: Edited subject to match content.

My T520 has recently developed a similar problem.
With no obvious warning it now seems unable to recognise the trackpad/point. I've tried various combinations of uninstalling/installing drivers etc with no success.
When clicking on the mouse tab in Control Panel an error message says: Unable to connect to the Synaptics Pointing Device. It then suggests removing the synaptics driver and then reinstalling other mouse drivers. This doesn't make sense as I don't have any other mouse drivers installed (bar the in-built Win7 ones which can't be removed anyway). Then rebooting the system results in no pointing devices being available at all. The trackpad gets recognised as a PS2-compliant device and prompts installation of drivers (from synaptic) which just gets back to square one.
Also, the control panel mouse tab won't show the ultranav utility even though that is installed properly.
So, I'm having to use an external mouse as the system doesn't seem to be able to properly use the trackpad/point. I'll keep troubleshooting but suspect this may be a software/driver issue as it was working perfectly up until recently and the hardware can still "see" the device. Both are enabled in BIOS.
Any other people experienced similar problems?

ScrollPane zoom in/out

Hello, this is my first post.
I'd like to add zoom in/out function to my ScrollPane, and make shortcut (CTRL+MOUSE SCROLL UP/DOWN) for it. ( like Inkscape )
I made the following code ( Canvas ) to achieve this, but have some problems.
*1. How can I prevent ScrollBar's thumb to move when pressing CTRL?*
When ScrollBar is visible and ScrollBar's thumb (or scroller, knob) has room to move, CTRL+MOUSE SCROLL UP/DOWN doesn't work because the thumb moves instead of zooming in/out.
When the thumb moves up/down to bar's end, then zoom in/out finally works fine.
*2. ScrollEvent handler is sometimes not called in ScrollPane*
When ScrollBarPolicy is not ScrollBarPolicy.ALWAYS and Scrollbar is not visible, SOMETIMES CTRL+SCROLL UP/DOWN operation dosen't work.
(ScrollEvent handler is not called. For other panes, ScrollEvent works fine. Please check MouseScrollEventTest below)
Thank you in advance.

Thank you for the good example.
But actually, I just give up using ScrollPane and created a ZoomCanvas which can zoom in/out and pan.
The code is here.
Any comments or improvement would be appreciated.
ZoomCanvas
public class ZoomCanvas extends StackPane {
     private ZoomController zoomController;
     private Group contentWrapper;
     private double translateXWhenMousePressed, translateYWhenMousePressed;
     private double xWhenMousePressed , yWhenMousePressed;
     private static class ZoomController {
          private int deltaCount = 0;
          private final double DEFAULT_ZOOM = 1.0;
          private boolean useAnimation = true;
          private DoubleProperty zoomMax   = new SimpleDoubleProperty(10.0);
          private DoubleProperty zoomMin   = new SimpleDoubleProperty(0.1);
          private DoubleProperty zoomDelta = new SimpleDoubleProperty(1.2);
          private DoubleProperty zoom      = new SimpleDoubleProperty( DEFAULT_ZOOM );
          public ZoomController() {
          public void zoomIn() {
               double zoomValue = DEFAULT_ZOOM * Math.pow(zoomDelta.get(), deltaCount+1);
               if( zoomValue > zoomMax.get() ) {
                    setZoom(zoomMax.get());
                    return;
               deltaCount++;
               setZoom( zoomValue );
          public void zoomOut() {
               double zoomValue = DEFAULT_ZOOM * Math.pow(zoomDelta.get(), deltaCount-1);
               if( zoomValue < zoomMin.get() ) {
                    setZoom(zoomMin.get());
                    return;
               deltaCount--;
               setZoom( zoomValue );
          public void setZoom( double zoomValue ) {

                    zoomTimeline.play();
               } else {
                    zoom.set(zoomValue);
