Set XY Graph Y-Auto Scale

I am trying to figure out how to set the XY Graph Plot View Y Autoscale based on the values visible NOT based on all the values in the historical arrray.
The goal is to be able to scroll left to right and have the signal centered on the XY chart. This functionality is desired because my signal
has a wide Y range and simply scrolling left to right I always end up zooming in then back out.
Any help on this would be appreciated

Simply turn off autoscaling and set the Y min and max under program control using property nodes.
In your case you could take the array subset of the history data accoding to the x range, then take "array min/max" of the subset to set the y scaling.

VM Auto Scale Problem

Hi Team,
I encountered a VM auto scale problem,
We have 3 VMs in a Availibility Set and configure VM auto scale, what we configured is that let 2 VMs running, the third one as a standby server.
when I look at the auto scale log, it's wired that the logs say it will scale from 1 instance to 2 instances.
paste part of the logs.
ActiveAutoscaleProfile:
"Name": "No scheduled times",
"Capacity": {
"Minimum": "2",
"Maximum": "3",
"Default": "3"
Description:
The autoscale engine attempting to scale resource 'daonortheuie2:EUIE-2-Media' from 1 instances count to 2 instances count.
LastScaleActionTime:
20140124T152458Z
NewInstancesCount:
2
OldInstancesCount:
1
Thanks in advance.

hi Baker,
According to your description, it seems the issue is related to Azure Monitor, alert and auto scale , I will move this thread to Azure Monitor, alert and auto scale Discussions forums to get a better support.

Xy Graph Auto Scale Bug - Need AutoScale VI

I have another bug to report, I have come across more bugs in the past year than before.
This bug is present in all versions since 7.1 to the latest 8.5.
Here is the bug.
Create and Graph.
Make sure the X-Scale is set to Auto Scale.
Go to Properties and Choose "Formatting and Representation" and Choose Relative Time for X-Axis . Select HH:MM.
Click OK
Now Set the scale to say 20 Hours. You Should see 10 Divisions of X-Axis
Right Click on the Graph and Select "Scale Object with Pane"
Maximize the VI now.
The Graph will scale nicely!!
Look at the X- Axis Scale. It is 20 Hours.
What happened to the 10 Divisions? It is one big Division of 20 Hours.!! Why?
Set the Scale to 10 Hours and all the divisions reappear!!
Restore the VI window to Previous and Now All divisions of the scale are gone.
This Behavior is random based on the size of the graph and Screen resolution.
Can someone suggest a VI that does Auto Scaling elegantly
Attached find Pictures of the Phenomenon and VI which exhibits this behavior. Any one to help...

Good Luck!

Turn off auto scale in XY graph when zooming?

Hi!
I have a xy graph with 3 graphs and 3 scales. Whenever I zoom in and then go back to "full view" one of my scales switches from a fixed scale to autoscale. The others stay fixed.
Anyone knows what this could be?
bye
hmann

Hello Hmann,
I'm not sure what's the behavior you talk about as you haven't provided an example, but I think this vi might help.
What you may need to do to avoid that behavior is to assign to each plot one Y Scale (you need to use the Plot legend to do this). I've done so in this example, and the Autoscale wasn't affected. Please let me know if this doesn't solve it and how to reproduce it step by step.
Regards,
Jorge M.

Is it best to set waveform graph scale properties before or after sending new data to the graph?

Hi I'm wondering when is the best time to update waveform graph scale properties.
I am sampling data every 15 minutes for 192 samples, i.e. 48 hours. I want to plot these samples with the x scale in absolute time mode so that x scale maximum is the current time and x scale minimum is x max minus 48 hours (172800 seconds). I also want the intermediate scale markers to be 6 hours apart and to be multiples of whole 6 hours. e.g. at 06:00, 12:00, 18:00. This works OK using property nodes but sometimes the intermediate markers are on the 6 hour multiples and sometimes they are at 6 hours after the min scale marker. e.g. 09:15, 15:15, 21:15. Is there a way of guaranteeing that the intermediate markers will be on the 6 hour multiples?
Thanks,
Neville

Hi Bryan,
Thanks for your reply. I have discovered that I can achieve what I want by using an XY graph instead of a waveform graph. I want X max to be the current time and X min the be 48 hours earlier with intermediate scale markers on multiple of 6 hours. The XY graph in the attached VI does exactly that but I can't get the waveform graph to behave as I would like. Is there a way of getting the waveform graph to behave as I would like?
Thanks,
Neville

BO XI 3.1 SP3 Auto Scale, how it works...

Hi,
I thought that the new feature: "auto scale" in graphs (SP3), helps us to create X-Y graphs with the same scale...
But I don't know how I have to use...
Could anybody give me a example?

Hi,
What kind of SSO authentication are you trying to set up? (AD, LDAP,...)
I think it's AD regarding your command line.
But be aware that in SSO, you don't need to configure the command line to run the client.
Have a look at the following guide.
[Configuring Manual Kerberos Authentication and-or SSO in Distributed Environments with XI 3.1 SP3.pdf|https://bosap-support.wdf.sap.corp/sap/support/sapnotes/public/services/attachment.htm?iv_key=002007204200000183782010&iv_version=0005&alt=2BCE4CB10DF674B172F4F3F7B32A284F49333135358877720E883731B332AF34CACD2AB52C0A2C8DCACA09084EF4CB494E4E0F2ECE8E2F89772908C9CE70CD2DF77675F7F2D1750C09514BCECFCFCE4C8DCF4BCC4DB5F575F4F4F3F57771F571F6F70B01B25D83D4120B0A722092A599504EB16D715E3E00&iv_guid=DF838310BFAAE8F1B486001A64C54696]
Regarding accessing CMC with SSO, it's not recomended at all as if you break this access, than you can't connect anymore to the CMC and modify settings.

Philippe

How do I set the default x-axis scale in DIAdem View?

Hi everyone:
I look at large amounts of data (i.e. many different data files every day), and I am trying to load and view them quickly and efficiently. Currently, when I have data sets loaded in the "Structure" tab, and I click and drag a numeric channel over to the 2-D plot, DIAdam automatically scales the x-axis from 0 to 60, when the numeric channels can be anywhere from 50 000 to 100 000 entries long. I now use the roller on my mouse to zoom out for five minutes before seeing the entire data set. My question is is there a way to re-set the default x-axis scaling so I do not have to zoom out each time I plot a numeric channel?
Solved!
Go to Solution.

Hello Peter!,
The DIAdem VIEW windows will always auto-scale to the full range of the values on the X-axis when you drag data into a new window.
You have several options on how to quickly get to the range of data you wish to see.
Right click on the LEFT edge of the data you wish to zoom into, HOLD the mouse right mouse button and DRAG the mouse to the right side of the section you wish to zoom into. DIAdem will automatically show the section you have selected in a zoomed view in that same window
Result:
Alternatively, you can double click on the VIEW window and check the "Manual X-Scaling" box and then enter the exact values you wish to zoom into
Also, you could use the Band Cursor from the toolbar, move and resize the Band in the VIEW window and then use the "Scroll in Cursor Range" icon to zoom into the area of the curve you are interested in.
These are just a few ways you should be able to accomplish what you have described in your post.
Let us know if you have additional questions ...

Changing cloud services auto scale weekends

hi
i want to change the default weekends in the azure auto scale ( our weekend is from Friday to Saturday ).
can it be done using the portal or in any other way ?

hi,
>>( our weekend is from Friday to Saturday )?
Base on my experience, if your weekend has two days, you could set weekend by selected the prior time zone .
About customize the weekend time, it may be difficult on azure portal.
Another way, I suggest you could try to auto scale could service by customize time using the Windows Azure Monitoring Services Management Library . I recommend you could refer to this code sample about how to use this library (http://blogs.msdn.com/b/cie/archive/2014/02/20/how-to-use-windows-azure-monitoring-services-management-library-to-create-an-autoscale-rule.aspx
). And you also see this document (http://msdn.microsoft.com/en-us/library/hh680945(v=pandp.50).aspx ).
Hope this helps.

Cloud service auto scale delay

Hi team,
We have a cloud service that have 10 worker roles, to let the cloud service can auto scale up/down, we configure the autoscale settings that if the average CPU reaches 70% and keeps last 30 minutes, new worker role instance will be created.
We also configure a email notification monitor that if the worker role average CPU reach 75% and keeps last 30 minute it will send a notification to our administrator, we receivce the notification at 2015/1/26 0:55 and 1 hour later the instances ware scaled
up, is that means the autoscale have been delayed about 1 hour , is there some best practise that avoid this kind of problem and let the instances can be scaled up immeditatly
thanks in advance.

Hi,
Please have a look at this article:
http://azure.microsoft.com/en-us/documentation/articles/cloud-services-how-to-scale/, here is a snippet.
All instances are included when calculating the average percentage of CPU usage and the average is based on use over the previous hour. Depending on the number of instances that your application is using, it can take longer than the specified wait time
for the scale action to occur if the wait time is set very low. The minimum time between scaling actions is five minutes. Scaling actions cannot occur if any of the instances are in a transitioning state.
Hope this helps.
Best Regards,
Jambor

I have set text size to Auto but it starts too small

I have created a form in Acrobat Pro 9, and set text size to Auto in all fields.
I know it is limited to the height of the field, but one of the fields is a block for multi-line paragraghs. Size is set to Auto, font to Times Roman. When I open the file in Reader to test it, it looks like it's starting at 12 points. It goes down from there as the whole block is filled with text, but I'd like it to start at around 18.
Advice?

as I mentioned, this one field is a block for multi-line paragraghs. It's one, large text block, taking up the bottom half of the form, so that users can input multiple paragraphs of text (they're telling their story). Some people will write a lot, some less. That's why I set it to Auto, so that the shorter stories would be in larger text, but longer stories will still shrink to fit.
It works, but I want to know if their is a way to get the text to start out at a larger font size before auto-sizing-to-fit. I mean, Something is telling the font to start at 12 point...
Should I attach the form to this discussion? (How do I do that?)

How do i set the iphone to auto sync with the mac book pro

how do i set the iphone to auto sync with the mac book pro?

Iphone Sync Support wrote:
Thanks but this is not what I am looking for. I am looking for the settings - setting that allows our iphone to auto sync with your mac book when you make a puchase on either device.
You aren't going to sync with my MacBook when I make a purchase.
And you are not going to autosync your iPod with the MacBook unless you tell it to sync or plug it in.
You can enable Automatic downloads when you make a purchase.
iTunes settings > Store.
When you make a purchase, it will automatically download that purchase to devices set up the same way.
This is not the same as autosyncing your device to your computer (as you first asked).

Difficulty controlling X-axis time display in auto-scale mode

Auto-scale mode is great in that I can zoom and pan and all the axes are updated, but the display of time is not very controlable. I specifically want the start and end time to always be displayed on the far right and left, and I want a decent number of subdivisions to always be displayed. In auto-scale mode non of this appears to be controllable. What can I do short of taking over control of all aspects of the chart scaling and axes control to get auto-scale behavior that is more reasonable?
Thank you,
Martin

Hopefully a picture is worth a thousand words..
I think this has something to do with Mode = AutoScaleLoose or something along those lines.

Graphing with logarithmic scale in AI5?

I received a graph in MS Excel that uses a logarithmic (as opposed to linear) scale, but as far as I know, it isn't possible to create a scatter-plot graph with logarithmic scale in Illustrator. Does anyone know if there is a plug-in or a script that can do this?
I am happy to upload the Excel file if that would be helpful. This is my first time using this forum, though, so I just need to know how to attach it.
Thanks

I found this link that has a plugin that states it does logarithmic scale, it is called ToolDemo here is the link, hope it's what you are looking for. http://www.telegraphics.com.au/sw/#tooldemo

Auto scale/crop with lens correction tool in Camera Raw 8.4

I understand the straighten tool offers this effect but I'm looking for in auto crop or autoscale feature when using the lens correction tool. Thanks in advance!

Good day!
I notice no difference to prior to 8.4.
