MATLAB: Plotting multiple boxplots within the same plot/figure

boxplots

I have six variables that I would like to plot within the same figure/plot as individual box-plots. I have tried doing so by plotting one, then using 'hold on' before the plotting the next, but this hasn't worked. How might I go about doing this?

Thank you.

subplot(3,1,1)
boxplot(mat1, 'notch', 'on', 'colors', 'r')
subplot(3,1,2)
boxplot(mat2, 'notch', 'on', 'colors', 'b')
subplot(3,1,3)
boxplot(mat3, 'notch', 'on', 'colors', 'c')

MATLAB: Ylim is not working

Use explicit axes handles for plotting instructions and instructions like hold, ylim, xlim. i.e.

hAxes(1) = subplot(3,1,1);
scatter( hAxes(1),... );
ylim( hAxes(1),... );
...
hAxes(2) = subplot(3,1,2);
...

doc linkaxes

useful if you want your axes to all have the same limits. If you store your axes handles in an array as shown above then you can simply replace all the individual ylim instructions with

linkaxes( hAxes, 'y' )
ylim( hAxes(1), [-50 50] )

MATLAB: Box plot labels not working for hold on

Managed to fix this (for anyone that stumbles across a similar issue in the future!). The issue was that the figure was only displaying three ticks (the final 3) and so when it went to assign tick labels, it only assigned them to the final three. I inserted the final line:

boxplot(Data(:,1:3),'notch', 'on','Colors',"r","Positions",X1)
boxplot(Data(:,4:6),'notch','on','Colors',"b",'Positions',X2)
boxplot(Data(:,7:9),'notch','on','Colors',"g",'Positions',X3)
xticklabels({'1mm A','1mm B','1mm C','1.5mm A','1.5mm B','1.5mm C','3mm A','3mm B','3mm C'})
set(gca,'xtick',1:9); %inserted this line!!

Which gave the plot 9 ticks, allowing all 9 tick labels to be displayed.
