Set the tick locations (and displayed values if different) to specific values, and specify the tick format —

x = zeros(1,5);
y = 1:6:30;

figure
scatter(x, y, 35, y, 's', 'filled')
yticks([0 4 15 30])                                                 % Set 'Y-Tick' Values (R2016b+)
ytickformat = '\bf %d';                                             % Set Bold Font Weight & Integers (R2016b+)
xlim([0 0.1])
