Starting in R2014b, the XTickLabel, YTickLabel, or ZTickLabel properties for a log axis contain cell arrays with the full TeX markup used for the tick labels. In previous releases these properties contain a character array with only the exponent values for the tick marks.
Starting in R2014b, this code returns the tick labels a cell array with the full TeX markup:
semilogx(1:10000);
ax = gca;
ticks = ax.XTickLabel
ticks =
'10^{0}'
'10^{1}'
'10^{2}'
'10^{3}'
'10^{4}'
class(ticks)
ans =
cell
In R2014a and earlier, this code returns a character array with the exponent values:
semilogx(1:10000);
ax = gca;
ticks = get(ax,'XTickLabel')
ticks =
0
1
2
3
4
class(ticks)
ans =
char
To extract just the exponent values from the tick label property, use the regexprep function with the following syntax.
expression = '\d*\^\{(\-?\d*)\}';
replace = '$1';
exponents = regexprep(ticks,expression,replace)
exponents = '0' '1' '2' '3' '4'
