MATLAB: Adding label to axis ticks

Question

How do I add labels next to the 3 180 xticks? Like sampleA for the first one, sampleB for the second, etc. Thanks!

>> xt = xticks
xt =
  Columns 1 through 5
           0         180         360         450         630
  Columns 6 through 9
         810         900        1080        1260
>> xtl=xticklabels
xtl =
  9×1 cell array
    {'0'  }
    {'180'}
    {'360'}
    {'0'  }
    {'180'}
    {'360'}
    {'0'  }
    {'180'}
    {'360'}

Answer 1

Set the XTickLabel propery of the axis. Use newline to break apart a string into multiple lines.

Quick demo:

ax = cla();
ax.XLim = [0,4];
ax.XTick = 1:3;
ax.XTickLabel{2} = '180\newline A';

"\newline" inserts a line break within the label.
