Error bar problem

This must be simple, but I can't figure out how to make either a standard deviation or a standard error bar to a chart.
I place the numbers 22, 33, 44 in three adjacent cells. I highlight them and see average in the lower left area. I drag this average button to a new cell, and viola the cell says 33. I click the cell and click chart and make a bar chart and get a chart that has a bar at 33. I then click the inspector and under advanced click error bars and positive and negative. For fixed value it works fine. For standard deviation or standard error, the error bar does not exist?!! How do I use the std dev or std error buttons to generate the appropriate error bar?
I can't believe this is a bug with the program, it must be a bug with me.
Please help,
Paul

Thank-you Yvan for your continued support. I have been working on this as well and spent some time with a VERY receptive and helpful Apple specialist, Chris. Indeed, what I was looking for was a chart like Yvan posted as Graphique 6. A version I created is here (hopefully I've got this image insert working:

I made the error bars by using a formula to generate the standard deviation:

Then generated custom error bars with that cell:

I just discovered that Excel implements the one-click error bars identically to Numbers. It is counterintuitive (to me and my coworkers who have listened to my ranting today) that the one click standard error or standard deviation buttons would not give the standard deviation or standard error plots on the average bar, rather than on a series of bars, as if they were independent data. Here is one of countless examples of data from peer reviewed scientific literature of how this type of plot is (and IMHO should be) used:
image: !http://picasaweb.google.com/lh/photo/5IQm4ncUiq-Q9R8H2bb3zQ?feat=directlink!
One can see that some of the values are within the standard error of the other values, and some are significantly different.
But I now realize that because the implementation is the same as in Excel, it is unlikely that the feature will be changed to what I see is a more logical use of the one-click button, since we can use the custom buttons if we really want to chart differently...
I want to thank Apple and the responders to this thread for their time and patience.

XY Graph, 2D Error Bar, Legend, Multi Plot Help? Please modify the VI

PLEASE READ THE ENTIRE POST and HELP!
Please help with this VI and make it an instructive example for me and other novices like me who come across this typical example.
A typical problem in plotting data is as follows: On the SAME plot (Y-axis = Amplitude vs. X-axis = Time), plot the curves Amp1, Amp2, Amp3, ... coming from sample1, sample2, sample3, ...
Furthermore, there is Error1, Error2, Error3, ... associated with Amp1, Amp2, Amp3,...., which also needs to be plotted. In order to distinguish between these curves, one may use different
colors and show a legend that reads Amp1 (say black), Amp2 (say red), and Amp3 (say green). The plot then becomes complete and conveys data very conveniently.
The attached VI makes an attempt to plot Amp1 and Amp2 using XY Graph and also 2D Error Bar plot (to show error bars). There is one slight problem. The legend does not show what it is supposed
to show. Can someone fix this? If I plot two curves, the legend should show Amp1 and Amp2, if I plot three curves, the legend should show Amp1, Amp2, Amp3, and so on.
I don't want to see the default Plot 0, Plot 1, or whatever. Also, it would be nice to dynamically control the symbol, color, curve style etc, as we keep adding more and more curves to the plot.
Once this problem is fixed, I know I can easily extend it to make it plot more than just two curves in a dynamic way. I could use for loops with shift registers, etc to plot any number of curves on a single plot.
Believe me, I have searched for other posts and cannot find a simple example like the one I have posted here. Many examples I found have confused me more than helped me.
I believe that if this problem is solved in a simple way, many others will find this example very instructive. So by helping me, you help many other people as well!
Thank you in advance. Please see the attached files (the VI, and an example data file that I just created)
Solved!

Some members have pointed out that this problem has already been resolved (see the link below).
http://forums.ni.com/t5/LabVIEW/Dinamically-handle-legend-names-using-property-nodes/td-p/1479572
I did verify that this works for XY Graph, but not for 2D Error Plot.
I need both legend and error bars. Shame on LabVIEW for not making such a basic plotting requirement easy and trasparent.
There are many clever people who can find work arounds, but that is a not a correct approach.

Standard Error Bars in charts

I would like to know if anyone has used std. error bars (as
in statistics) in column or bar charts and how that was
accomplished. I didn't see anything about it in the flex
docs.

Frustrating that these aren't included by default, isn't
it...
I'm sure the questioner long since has solved his problem or
given up, but since I've been unable to find any solutions myself
and have had to reinvent the wheel, I'll try and point anyone else
looking in the right direction.
One way to do it is to create your own IDataRenderer (or
extend or facade an existing one). You'll want to make sure you're
passing a standard deviation as part of your series data and then
in the updateDisplayList method draw it yourself, grabbing the
deviation from the data.item. You'll need to scale it
appropriately... for instance, extend CircleItemRenderer and add an
updateDisplayList along the lines of:
override protected function
updateDisplayList(unscaledWidth:Number,
unscaledHeight:Number):void
super.updateDisplayList(unscaledWidth, unscaledHeight);
if (data.hasOwnProperty('item') &&
data.item.hasOwnProperty('deviation')) {
// figure out the scale (I'm certain there must be a more
appropriate way to do this)
var scale:Number = data.y / data.item.value;
var deviation:Number = data.item.deviation as Number;
var g:Graphics = graphics;
var stroke:IStroke= new
Stroke(0,1,1,false,'normal','square');
stroke.apply(g);
// figure out the center
var trueX:Number = unscaledWidth / 2 - .5; // otherwise
seems to be off to the side, for me
var trueY:Number = unscaledHeight / 2;
// draw the error bar
g.moveTo(trueX,-(deviation * scale) + trueY);
g.lineTo(trueX,(deviation * scale) + trueY);
g.moveTo(trueX, trueY);
// draw little T's on the end of the error bar
g.moveTo(trueX -2, -(deviation * scale) + trueY);
g.lineTo(trueX +2, -(deviation * scale) + trueY);
g.moveTo(trueX -2, (deviation * scale) + trueY);
g.lineTo(trueX +2, (deviation * scale) + trueY);
From there you should be able to futz with it to make it look
pretty.
Hope someone finds this helpful.

Cannot define error bars for individual bars, has to be whole series

I am trying to make a simple graph that plots the mean and a standard deviation. (see picture in the link) I want to assign an individual mean values for each bar (i am able to do this), and an individual standard deviation for each bar (I cannot do this).
If I set one bar's standard deviation (custom), it also assigns the SAME standard deviation value for every bar in that series (all the green bars get the same SD value, not just the first one). I have 4 bars that I want different standard deviations assigned to (2 greens and 2 yellow = 4 different means, 4 different SDs). The standard deviations are listed in the lower table.
I can't do this. This is a fatal flaw in the software, and again, forces me to use a different application. Please tell me I'm doing something wrong! I love Numbers!

Please help if you can! Thanks!
Todd

I solved my own problem!!
If you want to set different error bar values for every bar in your graph:
-choose custom error bars (positive and negative)
-then delete the placeholder value that apple provides (usually 10)
-highlight MULTIPLE values in a table (these are the values you wish to have as error bars)
-bingo!
See picture!

Off center error bars

I'm using AI CS2, and am running OSX 10.3.9.
I use the copy/ paste function to copy graphs from a graphing program (Kaleidagraph) into illustrator. Whenever I paste a line graph with error bars, the error bars are always slightly off center to the object they are supposed to be centered on. When I paste the same graph into another program, the error bars are centered so I know this is an illustrator problem. Other components might be off center as well, but it is only the error bars that are noticeable.
I know this problem is fixable as someone managed to change something in illustrator to stop the off center problem when pasting into illustrator, but unfortunately that person can't remember how they did it.
Any help would be greatly appreciated.

Thanks for the reply Eileen,
Though that's not quite my problem. The line graphs I'm talking about will have several shapes in a line, (ie. a circle). When I make a graph, the circles will have a straight line down the middle of the circle (the error bar). When I than past this graph into illustrator, illustrator for some reasons off sets the straight lines of the center of the circle. The off set is less than 1pt, but is still noticeable. And it does it every time.

Error bars on column charts

I'm having a problem with inserting error bars into a graph. In the Series window I pull down the menu and select "standard error", but all my error bars are the same, no matter how many categories i have, or how variable the data are within each catergory. How do i get error bars to reflect the actual data from my spreadsheet? I've calculated the standard deviations and standard error and they are clearly different from what the graph indicates. I can't select my own standard deviation data and apply it to the chart?

Hi Jim,
I checked out your claim that the Standard Error bars don't change and I can't confirm it here. Everything seems normal. Here's my test with 20 data points, using a scatter plot for easier reading, but the result was the same...
And, here's the same function of randomized data with 53 points...
Same data with Standard Deviation...
All looks ok to me. It does require that you get the scale big enough to see the change in the error bars. I used a fixed scale for all three shots, and the data is =2+1.5*RAND().

Jerry

Error bars, error more.

I have updated to my Numbers after Mavericks update. Before that I can use my Numbers smoothly, but after an update, I found that some of my old files cannot open with the new version of Numbers. Furthermore, the error bars of the graph seem to have multiple problems. My program shuts down almost everytime I try to add error bars. And if it does not shut down, one or two bars diappear, e.g., when I added 6 error bars, only 5 showed up, skipping one bar in the middle, and the last error has never shown up. I guess it's the software problem and I hope that Apple will fix it soon. But if any of you know how to troubleshoot these problems, I greatly appreaciate.

Error Bars Stopped Working

I'm having trouble with custom error bars in Numbers 09. I created one scatter plot and successfully added positive and negative error bars with defined values. When I created a second scatter plot with different information, the error bars with custom values selection was grayed out. I closed and reopened the file, closed down the program, ran repair permissions through Disk Utility, and rebooted the machine. For some reason, I've suddenly lost custom error bar functionality. To make sure the issue wasn't associated with my data values, I ran the same data through Excel and was able to generate the graphs with custom error bars.
(When I say custom error bars, I'm referring to defining custom values from standard deviations)
Any body have any clues. A Google search and Discussion search hasn't yielded any results.
Thanks.

Ok, not too sure what I did to fix the problem, but the issue is now fixed. For those of you who may be experiencing the same issue, here is what I did to correct the problem. Following everything I did in my first post, I trashed the Preference plist ~/Library/Preferences/com.apple.iWork.Numbers.plist. I reopened the file and clicked on the line in the chart representing my data (don't just click the chart, you have to click on the line itself). Voila!!! I have now restored functionality.

How can I display different error bars for each point on a scatter graph?

I have a scatter chart in Numbers and I need to add error bars to the points along both the x and y axes, however, the size of the error bars for each point need to be of different sizes. Is there a way to accomplish this or is there some kind of work around to acheieve a similar result? So far the only way I can find to add error bars only allows a standard amount for each point.

I found the answer here https://discussions.apple.com/message/16440653#16441393

OWA error: A problem occurred while you were trying to use your mailbox (Exchannge 2010 SP3)

Hi!
I have several mailboxes that are was moved from Exchange 2007 to Exchange 2010.
Sometimes occurs a problem: in OWA may appears error "A problem occurred while you were trying to use your mailbox" when selecting interface elements (such as "Options", "Public Folders",
"Reminders"). After this error user cannot access to mailbox through OWA during 10 minutes. The error "A problem occurred while you were trying to use your mailbox" appears in top of browser window on any computers. This behavior is manifested
in any browser, but it can not be associated with any particular event.
Access to mailbox through Outlook or through mobile devices (ActiveSync) continues to work fine in this time.
The errors in Application log on Client Access Server is absent (including error with EventID 9646). ExBPA is not showing anything specific to that error message. Test of OWA connectivity working successfully.
In the logs of IIS finded records:
2014-08-26 09:23:01 172.16.0.31 GET /owa/ &ex=UE:Microsoft.Exchange.Data.Storage.TooManyObjectsOpenedException 443 DOMAIN\username 172.16.4.218 Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+6.1;+WOW64;+Trident/5.0;+SLCC2;+.NET+CLR+2.0.50727;+.NET+CLR+3.5.30729;+.NET+CLR+3.0.30729;+Media+Center+PC+6.0;+InfoPath.3;+.NET4.0C;+.NET4.0E;+.NET+CLR+1.1.4322;+MS-RTC+LM+8)

Someone faced with such issue?
Have ideas to solve the issue?

Hi,
Event 9646 occurs if a MAPI client opens more than the default value. You can follow the steps below for troubleshooting:
1. Run regedit, and then click OK.
2. Expand the following registry subkey:
HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
3. Right-click ParametersSystem, point to New, and then click Key.
4. Type MaxObjsPerMapiSession, and then press ENTER to name the new subkey.
5. Right-click MaxObjsPerMapiSession, click New, and then click DWORD Value.
6. Type Object_type, and then press ENTER to name the object.
Note: Object_type is the name of the object type in the error message that is mentioned in the "Symptoms" section.
Hope this can be helpful to you.

Error logging problem:

error logging problem:
I would like to implement an error logger that will do the following tasks when a error/exception arrises:
- surpress the DacfErrorPopupLogger
- alert the user that an error has occured with a simplified popup (create a global listener then use the ErrorAttributes to create the text of the popup)
- log the error in a file with a timestamp and all error information
- later if the above works....i would like to add the error attributes (time stamp, error type) to a oracle object/ Jdev domain.
Questions:
What is the best technique to use....errorManager, error logger ...?? combination
How do i use the error manager to register listners for the errors?.
In the following code i am not sure how to access the ErrorsAttributes[] array that is returned by loggerReader.getErrors();
Any general tips places to find sample code on errorManager or associated interfaces, will be appreciated
I used the OutPutStreamLogger to write error information to a FileOutputStream then a loggerReader to get the error attributes from the file. The reason i went in this direction is because i found some smple code on the outputStream logger.
package DACVideo;
import oracle.dacf.util.errorloggers.*;
import oracle.dacf.util.errormanager.*;
import oracle.dacf.util.errorloggers.InputStreamLoggerReader.ErrorAttributes;
import java.io.*;

public ErrorLogger() {
System.out.println("==============ErrorLogger Created==============");
//remove default error logger (popup logger)
ErrorManager.removeErrorLogger(ErrorManager.findLoggerByName(DacfErrorPopupLogger.NAME));
try
logger = new OutputStreamLogger(new FileOutputStream("out.dat"));
loggerReader = new InputStreamLoggerReader(new FileInputStream("out.dat"));

Scatter Chart Error Bars Help

I'm new to using iWork for my lab reports and today, while I was plotting a scatter chart, I had to put some error bars on the points in percentage form. The value for the x-axis was 0.5% and the value for they y-axis was 1.5%, and when I tried to input these, the only thing I got was the error sound and the error bars returning to 3% and 1% respectively. Anyone know why this is happening and how i might resolve this issue? Thank you in advance.

Angelos,
I'm sure that your eyes are sharper than mine. Still, if your error bar is shorter than the radius of your symbol, you aren't going to see it. The standard symbols are roughly 4mm in diameter, based on the Numbers Rulers. Let's say you have a 100 mm tall chart, an average graphic size. A 0.5% error bar would be a maximum of 0.5 mm in length, unless you suppress the axis zero, and would be hidden behind the 4 mm dia. data symbol. Yes, you could see a 3% or 4% error bar, but I'm not sure everyone would recognize that it was an error bar and not part of the data symbol.

Jerry

Error bars in Numbers for iPad?

Greetings,
One of the reasons I purchased an iPad was to work on the go. For me this means being able to create/edit docs, spreadsheets, and presentations in my iPad and then sync that work with my MBP at work.
I am finding some roadblocks when sharing work between devices (a first for me with Apple).
This specific question has to do with Numbers for the iPad:
- Is there a way to add error bars within Numbers for the iPad?
When I try to import a spreadsheet from Numbers in my computer the error bars get cropped as if they were some unnecessarily fancy font that didn't make it to the iPad version of the software. If there is no way to do this, does anyone know if there are plans to add this capability to the program?
I might be biased, but I have a hard time coming up with occasions when one would not need to add a measure of variability (error bar) to any graphic dispplay of data (save for ninth grade presentations maybe).
Thank you for your assistance!
Andres

Hi Andres,
iWork for iOS applications are in version 1, and in general provide a subset of the features of the Mac OS versions. Few of the users in this (Numbers) community are familiar with the iPad version, which probably explains the lack of response to yur question in the nine hours since you posted.
I expect you'll get a quicker (and more useful) response if you repost in the iWork for iOS area: https://discussions.apple.com/community/app_store/iwork_for_ios?view=discussions
