Error bars in keynote

Does anyone know how to manually insert individual error bars in a bar chart in keynote? the custom option is greyed out in keynote and when I tried it in Numbers I could only use the same value for all the columns rather than specify for each.
Cheers

Thanks for your reply; if this is the case then I must admit to being slightly disappointed. From looking at the Keynote tutorials I am aware that Keynote is not intended as an application through which to present scientific data, but because Apple usually include so many more useful features in their applications than Microsoft do (in my opinion), I thought they may have given us the option to add error bars to graphs and charts.

Error bars in Charts?

Hello everyone- Would anyone know how to create error bars in charts in Keynote 3? I can't seem to find an answer anywhere to this question. Many thanks to future replies...

You can't get Keynote charts to generate error bars, or to use error bar information from some other source -- that functionality just isn't available in natively-produced Keynote charts.
However, charts that are copied from Excel and pasted into Keynote look quite good. You won't get all the cool textures, or 3D effects that you can with Keynote charts (and not having the latter is a good thing in my book). But, if you set the background of the chart to "None" from within Excel, the chart background will be transparent in Keynote, and you can do things like apply shadows that will conform to the chart elements. Any formatting that you do in Excel should be respected by Keynote.

How to put std dev error bars in a chart

Page 141 of the Keynote User Guide states that error bars can be shown on plotted series data. Can anyone get this to work as expected with standard deviation bars for each plotted mean value? I spoke with an Apple Tech Rep today who supposedly knows Keynote well, but he could not get std dev error bars to display properly on a line chart.
Numbers has the same instructions as Keynote and seems to be designed to work the same way.

"Properly" means placing the error bars around the mean values for each data point in a series. In my case, the x-axis is time in minutes and the y-axis is concentration of a chemical.

Linked charts: Error bars are not updated

Linked charts work well: Changed values for bar graph and line graph y values in Numbers are reflected in Keynote and Numbers after “updating”. However, I cannot get error bars to be updated as well. They just keep the values they had when I first paste a graph into Keynote or Pages.
Is this a bug, or am I missing something?

It seems that you missed something.
In the Pages User Guide we may read:
*+Updating a Chart Copied from a Numbers Document+*
+If you’ve created a chart in Numbers, you can copy it and paste it into your Pages document. After it’s been pasted into Pages, the chart remains linked to the data tables it references in Numbers. To change the chart data, open the original Numbers document and edit the data there, save the Numbers document, and then refresh the chart data in Pages.+
+To update a chart after you’ve updated its linked Numbers table:+
+• Select the chart on the page and click the Refresh button that appears.+
+Note: You must save the Numbers document before copying and pasting your chart into your Pages document and after editing the Numbers data tables that the chart references.+

Confidence interval error bars in charts

Hello, does anyone know how to put the error bars on a chart?
I can make a bar graph from my data but I need to add the error
bars based on the confidence intervals of my data. Is there a way
to do this? Can CFReport Builder do this?
Thank you.

Individual error bars in charts

I can't figure out how to put individual errors bars in a bar chart. That is, a different amount of error on each bar. It can be done in Numbers by putting a range in the 'custom' option, but 'custom' is not selectable on my version of Keynote 09. I know i could just copy a Numbers bar chart and paste it into Keynote, but i'd prefer to do it directly in Keynote.
Anyone know how to do it?

In the Chart Inspector, click on the Series tab. Then click on the triangle next to Advanced at the bottom. That will reveal tabs to set trendlines and error bars.
Edit: OK, Just reread your post and I see that you're looking for a way to set conditional error bars that depend on each bar's value, correct? If so, I don't see any way to do that - the custom setting is not available.

Error Bars are essential on Graphs -- how do we make them animate?

I give a lot of talks with data, and have to have error bars. Is there anyway to animate data and show error bars? The animated graphs are very sexy but without error bars i can't use them ;(

I wouldn't count on anyone official at Apple reading the forums -- if you want to request a feature I'd do it at the Keynote feedback page.

Error bars?

Please tell me that you can add error bars to the 2D graphs...

I am not sure but I don't think so... I only have the trial version but I can't find any mention of error bars anywhere.
It is actually somewhat of a feat(!) to release spreadsheet software without that very basic functionality. Numbers can calculate StDev but not show it in a graph! Apple seems determined to make sure their so called "Work"-software is useless to the scientific community. The lack of error bars has bothered me in Keynote for years. It would be dead easy to implement and is actually the only thing that prevents Keynote from being used at thousands of seminars at universities around the world - every day. I thouht this would be resolved with the release of Numbers but I was probably wrong.
Hope I am wrong and that error bars are somewhere in a menu I have not found!!

Error bars on graphs

I was desperately hoping that Apple would include the ability to add error bars to charts in this release. As a research faculty member, I simply cannot present data at conferences without having error bars on the graphs. It is a shame, because I have heard numerous others in the life sciences make the same complaint - we would love ot switch to using iWork completely, but the lack of error bars is a deal-breaker.
Anyone have a reasonable workaround? Right now I end up creating the graphs in Deltagraph or even Excel, and then exporting them as jpgs and using them, but it is not as fast or as good looking as if I could just do it in Keynote/Numbers.
Ideas?

I'm also an academic (social sciences), and I also was disappointed that there wasn't an option for error bars. I don't really blame Keynote for this--I have low expectations of presentation software creating good data visualizations--but--but I was assuming it would be in the new Numbers application, and with that the feature embedded in Keynote's charts.
At least Keynote does still do a nice job of taking in graphs from other applications. I just copy and paste (via export or screen grab) from JMP (or SPSS or Excel) and directly paste into a Keynote slide and go from there.

Error bars in graphs?

I'm trying to create a scientific presentation in Keynote. It ain't Powerpoint. And even Powerpoint is pretty bad for science. But I want nice-looking graphs, so I'm trying.
One essential feature in graphing software is a way to create error bars (apart from drawing them oneself). I can't find any info on this. Does anyone have some tips or tricks? Many thanks / Matt

Matt,
unfortunately, Keynote doesn't offer error bars (see also http://discussions.apple.com/thread.jspa?messageID=2390999&#2390999).
You might also check Grapher.app in theUtilities folder.
And then there's GnuPlot, which offers xerrorbars and yerrorbars. Check http://www.columbia.edu/~sl2403/gnuplot/intro/style-e.html and http://lee-phillips.org/info/Macintosh/gnuplot.html
If this information is useful to you, please mark it as "helpful" or "solved" using the little buttons in the titlebar of this message. Thank you.

ERROR BARS ON CHARTS

Does anybody know of a simple method to add error bars to the charts in Numbers or KeyNote. without error bars, graphs really do not tell us anything. The only way that I can see to add error bars is to draw them on manually, which is rather tedious. I know that this is not a full blown graphing package, but error bars seem to be an easy thing to implement. Is there some hidden feature that I cannot find.. please tell me so. If not, Apple team, please add this in the next release! This is such a useful feature.

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

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

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).

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.

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

Barry
