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.

  • Adjusting error bars in graphs

    I have a bar graph set up, but I am trying to manually create the error bars for each data point. I need to show a different value for these error bars for each individual data point because they all have different ranges. I understand how to custom set a value for the error bars, but they can't all be the same. Is there any way to adjust the error bars individually?

    No, you can make custom error bars that are different for each data point. The table must include a column (or row) of error bar data, or two columns/rows if you want different sized bars for positive and negative. I would have posted this screenshot before but I forgot I had it (from May 2009).

  • 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

  • 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.

  • 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!

    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 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.

  • 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

  • Error bars in illustrator

    help!! I need to insert the standard deviation in a column graph created in illustrator...how can i do this?

    Plot the upper bound and lower bound error points as data sets in a line graph and then connect the dots.  Once errors bars are drawn in, remove the upper and lower bound data sets.

  • Legend, error bars, 2nd y axis etc

    Hello all,
    Measurement Studio is a powerful program. But it's graphing functions need improvement. As a scientific tool, for example, the lack of plotting error bars in CWGraph is unforgivable. And many other essential functions for producing decent graphs are missing. So I attempted to try to fill in some gaps. The attached program intends to do following:
    1) Plots x- and y error bars.
    2) Legends for data sets,
    3) Graph saving,
    4) Graph printing
    Notes:
    1)Error bars are not plotted symmetrically. They can be improved.
    2)Legends can be improved by making them automatically located in the empty part of the plotting area. And the routine doesn't work well for the logarithmic scale.
    3)Since the point sizes are tied to line size, it is impossible to use larger symbols without increasing the size of the lines!
    4)y axis and the 2nd axis labels as rotated have terrible looking fonts.
    5)When printing to a pdf file, filename can be automatically set to a default filename so that a dialog box can be avoided.
    I hope the attached program is useful.
    Sincerely,
    Cem
    P.S.
    The program plots 5 data sets. 4 of which use left y-axis, the last one uses the right axis. Only y error bars are plotted. (x error bars optional). The legend text appears on the left upper corner. User can enable/disable legend, lines connecting data points, error bars, and grid lines. When log axis is chosen, the legend placement is screwed up.

    Thanks for sharing this with us Girit. I'm sure this will help out alot of people on the forum.
    For your legend, this document provides another way you might be able to create a legend and not have to deal with finding an empty place on the graph.
    Thanks again

  • 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.

  • Standard Error Bar

    I'm exploring Flex as a candidate to use for developing a web application that displays many graphs.  The data displayed on the graphs are discreate values with associated stardar errors.  I need to display the standard errors as an error bar - similar to how MS Excel displays error bars.  Can anyone tell me if this can be done with Flex?

    V,
    Numbers does the best it can with the information you give it. If you ask for Error Bars, Numbers will calculate the standard deviation for the series and assign that calculation result to each of the bars in the series.
    If each of your values represents some statistic that in itself is accompanied by a standard error, that's another thing, but Numbers doesn't know what the error values are unless you tell it. The way to tell Numbers what the error bar values should be in these special cases is to use Custom values.
    Here's an example:
    I like to use the Scatter Chart, but you will find similar controls for the bar chart.

  • Creating error bars on numbers 09

    I'm new to Numbers and I'm trying to draw error bars on my scatter graph.
    To draw the graph, I clicked on the chart button, chose scatter graph and just altered the info in a table that popped up to make my chart.
    To draw error bars, I went to the chart inspector and clicked on the series tab. I know I need to click on the Advanced button but I can't click it and the data section is empty. I can't click on that either and I can't figure out what I'm doing wrong.

    To select a series, first click on the chart then click on a bar/line/data point of the series for which you want the error bars. Actually, turns out you don't have to select the data series anyway. Sorry for the misinformation.
    I do not know why you can't select error bars. I'll have to play around some and see if I can get it into that state.

  • 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!

    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.

  • 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.

    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.
