Error Bar Histogram


In principle I can use the patch handles returned by bar, but I don't understand how to do this. M=2; N=3; mu=rand(M,N); sigma=randn(M,N); [M,N]=size(mu); h=bar(mu); hx=get(h,'XData'); hy=get(h, 'YData'); hold on; hx=get(h,'XData'); x=[hx{:}]; x=reshape(mean(x(2:3,:)),M,N); errorbar(x1,mu,sigma,'.'); hold off; Subject: bar chart with error bars From: Ana Bernardos Ana Bernardos (view profile) 1 By hx=get(h,'XData'), hx is an N-by-1 cell array; hx{i} is a 4-by-M matrix such that hx{i}(1,m), hx{i}(2,m), hx{i}(3,m), and hx{i}(4,m) are, respectively, x-value of bottom-left, top-left, top-right, and bottom-right vertex of Try our newsletter Sign up for our newsletter and get our top new questions delivered to your inbox (see an example).

The resulting error bars, should be unique to each bar in the chart. Aside: As discussed in the paper mentioned below, it's actually debatable whether you should use this variance to obtain error bars.

Error bars often represent one standard deviation of uncertainty, one standard error, or a certain confidence interval (e.g., a 95% interval). Histogram Standard Deviation However, we can make a twoway graph that has error bars as shown below. The Sensible Way Well, we were led down the path of the above derivation by our idea that there are two sources of error in our bin total - how many Choose and customize the type and amount of the error range.

It's surprisingly difficult to find things using this name online, so we'll go through the derivation of the relevant case. (You can look up Wald's Equation for more information.) Derivation of Then, given mu and sigma (they must be of the same size, as you know), try [M,N]=size(mu); h=bar(mu); hold on; hx=get(h,'XData'); x=[hx{:}]; x=reshape(mean(x(2:3,:)),M,N); errorbar(x,mu,sigma,'.'); hold off; Hope this helps!

User error bars in such 3D graphs as XYZ 3D scatter, matrix 3D scatter, 3D color fill surface, and 3D color map surface. Want a fresh copy? For example, you could show 5 percent positive and negative potential error amounts in the results of a scientific experiment: You can add error bars to data series in a 2-D You might want to graph the mean and confidence interval for each group using a bar chart with error bars as illustrated below.

No single entity “owns” the newsgroups. However, we can finesse the twoway bar command to make a graph that resembles the graph bar command and then combine that with error bars. It creates metaSamples such histograms, and then compares the actual standard deviation of the gathered distribution with the (average) estimate of the variance according to the above formula. On the Format tab, in the Current Selection group, click the arrow next to the Chart Elements box, and then click the chart element that you want.
