The data set consists of measurements of 150 flower samples from each of three species of flowers: Iris setosa, Iris virginica, and Iris versicolor. The measurements are in mm. Four features were measured for each sample: The length of the flower sepal The width of the flower sepal The length of the flower petal The width of the flower petal All 150 samples from the Fisher iris data are stored in a single table called meas: The four columns correspond to the four types of measurements: sepal length, sepal width, petal length and petal width, respectively. The first 50 rows contain data for Iris setosa The second 50 rows contain data for Iris virginica The third 50 rows contain data for Iris versicolor. The species information is kept in a separate vector called species. The data is sometimes referred to as Anderson's Iris data in honor of Edgar Anderson, the biologist who collected the data. See http://en.wikipedia.org/wiki/Iris_flower_data_set for additional information. Note: This dataset comes with the MATLAB distribution so you don't have to download it separately.

Thanks Baz I also error bars matlab have a question where I try to achieve the same thing with boxplot but I'm not sure which (if indeed either of them can) can do it. Matlab Boxplots x = 1985:.05:2001; % x data grad_ = rand(1,length(x))*.3; % graduated stuff grad_2 = rand(1,length(x))*.3; grad_3= rand(1,length(x))*.3; h = subplot(1,3,1); errorbar(grad_,x,grad_2,grad_3,'o'); axis(h, [0 0.6 1985 2001]) set(h, 'Ytick', x(1):x(end), 'Xtick', 0:.15:.6, 'YDir','reverse', 'YGrid', 'on'); xlabel('Gradient Search') matlab plot matlab-figure share|improve this question edited Nov 26 '13 at 21:38 asked Nov 26 '13 at 20:05 Bazman 61321635 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote accepted The matlab function errorbar can create an asymmetric error bar and does not require a bar graph. close all x = 1:3; y = [4 6 3]; lower = [1 4.5 0]; upper = [4.2 2 4]; errorbar(x, y, lower, upper, 'o') share|improve this answer answered Nov 26 '13 at 20:37 Molly 7,00321221 add a comment| up vote 1 down vote Here's what I came up with: x = 1985:.05:2001; % x data grad_ = rand(1,length(x))*.3; % graduated stuff h = subplot(1,3,1); plot(grad_,x); % flip x and y for vertical plot axis(h, [0 0.6 1985 2001]) set(h, 'Ytick', x(1):x(end), 'Xtick', 0:.15:.6, 'YDir','reverse', 'YGrid', 'on'); xlabel('Gradient Search') diff_ = rand(1,l
