Plotting multiple boxplots within the same plot/figure

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() ?

I'm not quite sure how I would use subplot(). Below is essentially what I have tried.

boxplot(mat1, 'notch', 'on', 'colors','r') hold on

boxplot(mat2, 'notch', 'on','colors','b') hold on

And so on...

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')

I realize I wasn't being clear about what I needed to do.

I need them to be side-by-side boxplots.

Would you be able to help me with this instead?

This worked:

NMat= zeros (6, 10000); mat(:,:)=NaN;

mat(1,1:10000) = mat1; mat(2,1:10000) = mat2; mat(3,1:10000) = mat3;

mat(4,1:10000) = mat4; mat(5,1:10000) = mat5; mat(6,1:10000) = mat6;

NMat=mat; NMat=NMat'; boxplot(NMat, 'notch', 'on', 'colors', 'rb')

[Walter Roberson]

shortcut:

NMat = nan(6, 10000);

And since you are copying the same number of columns for each you can eliminate the other lines:

boxplot( [mat1(:), mat2(:), mat3(:), mat4(:), mat5(:), mat6(:)], 'notch', 'on', 'color', 'rb')
