MATLAB: Custom labels for errorplot

custom labelerrorplottext box code

Hi all,

is there a way to add custom labels to each errorbar in an erroplot using a code (instead of a manual text box)?

In my case I want to add one label at the bottom of the negative bar -> displayed above in the example below as the yscale is reversed).

using annotation

annotation('textbox', pos, 'String', str, 'FitBoxToText', 'on');

pos is the position where you want to put the textbox in [x, y, width, height], and string is what you want to show.

Some plot functions don’t work and play well with datetime objects for some reason. A work-around is to use the datenum and datetick functions:

datums = ['25-09-2015'; '01-10-2015'; '06-10-2015'; '08-10-2015'; '15-10-2015'; '20-10-2015'; '21-10-2015'; '26-10-2015'; '27-10-2015';'28-10-2015'];
datnms = datenum(datums,'dd-mm-yyyy');
piek1 = [-4;-5;-6;-8;-1;-2;-4;-3;-4;-5];
error1 = [0.3960; 0.5300; 0.4830; 0.1800; 0.2330; 0.4210; 0.5910; 1.0170; 1.6480; 0.7370];
figure(1)
errorbar(datnms,piek1, error1)  % gives error
datetick('x', 'dd-mm-yyyy')

You also had an error in your date format. The two-digit ‘month’ format is 'mm', minutes is 'MM'. (I fixed those here.)

Hi Jason,

you can use "text" command to print text into a bargraph. You have to build the string using your y values. For the vertical oriantaion you can set the property of the text handle to

text(x,y,'String','Rotation',90);
