### Pretty boxplots

This bit of code makes some nice boxplots. Some touching up in Inkscape or Illustrator is sometimes necessary.

% beautiful matlab boxplots % John Bogovic % November 2011 %% some parameters for the plots % the order that the tags should appear on the boxplots grpOrder = {'Group1A','Group1B', 'Group1C', ... 'Group2A','Group2B', 'Group2C'}; % positions on the x-axis to drop boxplots pos = [1 2 3 7 8 9]; % this tag tells matlab which boxes should be the same color % let's color the letterd groups the same way. allcolorgroups = {'A','B','C','A','B','C'}; % a color map cmap = hsv2rgb([0 0.6 0.6; 0.3 0.6 0.6; 0.6 0.6 0.6]); %% gen some fake data datmtx = randn(600,1); % randomly pick a group for each measurement grpi = randi(6,600,1); grp={grpOrder{grpi}}; % make an appropriate colorgrouping cgrp = {allcolorgroups{grpi}}; %% make boxplots figure; % make the boxplots % the 'compact' plotstyle goes a long way toward making things nice % group colors, and spacings along the x-axis are great in guiding the eye boxplot(datmtx,grp,'plotstyle','compact','grouporder',grpOrder,... 'symbol','k.','positions',pos,'colorgroup',cgrp,'colors',cmap,... 'medianstyle','line'); grid on; % make median lines black and big set(findobj(gcf,'Tag','Median'),'Color',[0 0 0],'LineWidth',2); % make outlier dots gray and big set(findobj(gcf,'Tag','Outliers'),'MarkerEdgeColor',[0.4 0.4 0.4],'MarkerSize',5);
