MATLAB: How to add space between labels values and its represented values in a plot

MATLABplotplottingtext;

The following code, plots the black dots. I'd like to create some separation between the black dots and the red label number of each dot.

for i=1:nr_BBU
   plot(BBU(i,2), BBU(i,1), 'k.', 'MarkerSize',25)
   labels = cellstr(num2str([i]'));
   %text(BBU(i,2), BBU(i,1), labels, 'Color', 'r', 'HorizontalAlignment', 'left', 'Position', '2')
   text(BBU(i,2), BBU(i,1),labels,'HorizontalAlignment','center','VerticalAlignment', 'bottom',...
       'Color', 'r', 'FontSize',12)
   hold on
end

Best Answer

You can add vertical space by increading the value of the 2nd input to text()

text(BBU(i,2), BBU(i,1) * 1.05,labels, . . .)
%              ^^^^^^^^^^^^^^^

or by using labelpoints() from the file exchange. This line below plots the labels North ("N") of the points with a buffer space of 10% (0.1) of the axis range.

labelpoints(BBU(i,2), BBU(i,1), labels, 'N', 0.1, 'Color', 'r', 'FontSize', 12)
%                                            ^^^ buffer

(continuing from comment section under the question)

To show the min or mean, substitute those values in for the max value in the line below.

plot(1:nr_BBU, max1, 'r.' , 'MarkerSize', 15) % 
%              ^^^^ max value

How easy would it be to over plot a boxplot ?

A boxplot isn't what you're looking for. A boxplot shows the quartile ranges, not the max and min. You could, however, use a vertical errorbar.

data = randi(20,1,6); 
bar(1:size(data,2), data, 'DisplayName', 'Data')
minData = min(data); 
maxData = max(data); 
meanData = mean(data); 
hold on
errorbar(size(data,2)+1, meanData, meanData-minData, maxData-meanData, '-d', 'Vertical', ...
    'LineWidth', 2, 'MarkerSize', 10, 'DisplayName', '[min, mean, max]')
legend()

or horizontal reference lines

data = randi(20,1,6); 
bar(1:size(data,2), data, 'DisplayName', 'Data')
minData = min(data); 
maxData = max(data); 
meanData = mean(data); 
yline(minData, 'k-', 'Minimum')
yline(maxData, 'k-', 'Maximum')
yline(meanData, 'k-', 'Mean')
ylim([0, maxData+2])
