MATLAB: Setting additional specific axis tick marks

plotting_basic

I have a y axis that spans 0 – 15. I want to place an extra tick mark (labelled with its value) at the minimum value of y (0.018 in one data set, for example).

It is not appropriate for me to use a log scale – the data is well presented, it is just not obvious to the reader that the minimum value is not zero.

Thank you.

set(gca, 'YTick', sort([0.018, get(gca, 'YTick')]));

Method 1: remove some X|YTickLabels

Add these lines to then end of your code after setting the axis limits and axis ticks.

The tickInterval variable defines the interval of ticks to display.

tickInterval = 4; 
ax = gca(); 
ax.XTickLabel(~ismember(1:numel(ax.XTickLabel), 1:tickInterval:numel(ax.XTickLabel))) = {''}; 
ax.YTickLabel(~ismember(1:numel(ax.YTickLabel), 1:tickInterval:numel(ax.YTickLabel))) = {''};

Method 2: Use Minor Ticks

This method may not be available on all types of axes.

ax = gca();
ax.XTick = 0:5:25;      
ax.YTick = -25:5:25;   
ax.XMinorTick = 'on';   
ax.XRuler.MinorTickValues = 0:1:25;
ax.YMinorTick = 'on';
ax.YRuler.MinorTickValues = -25:1:25;

Also see ax.XRuler.TickLength to change the tick lengths.
