Error Bars in WAD Chart

All:
Can anyone tell me if it's possible to add Y Error Bars to a chart in the Web Application Designer v3.5? I'm able to add a trendline to the data series, but do not see an option for error bars.
Thanks in advance...

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.

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

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.

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 add error bars in Interactive Chart?

Thank you very much. Sorry for not explaining enough.
I calculated errors and added error bars in Basic Charting as follows.
But I couldn't add error bars in Interactive Chart.
What should I do next?

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:
image: !http://picasaweb.google.com/lh/photo/HeCHRLWhs3C79ewObd_TdA?feat=directlink!
I made the error bars by using a formula to generate the standard deviation:

Then generated custom error bars with that cell:
image: !http://picasaweb.google.com/lh/photo/5IQm4ncUiq-Q9R8H2bb3zQ?feat=directlink!
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.

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.
Regards,
Jerry

Error bars in Charts?

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.+

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.

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 - Can Error Bars be added to Crystal Report Charts

I am trying to add or create "error bars" in my cystral report chart (graph). I can add "error bars" in an Excel sheet chart (graph) but I cannot find the functionality in crystal reports.
Is it possible to "error bars" to a crystal report chart. If so, how?

Hi,
I don't see that this functionality or this kind of chart exists in CR.
I would suggest that you log an Enhancement Request at http://ideas.sap.com and let our developers look into this.

Does anyone know if crystal repotrs xi can do error bars like in excel. I gave an example in my other post.

If all else fails, this is easily solved with our CRChart replacement library (which does excellent error-bars).

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.
