Hi!

I'm plotting 6 graphs using the subplot() command. I'd like 3 rows and 2 columns, however all the graphs are squeezed at the top and i'm not sure how to shape them so that they are nice and readable.

Here's how i'm plotting it:

% Plotting finite difference gradients
figure(1)
subplot(821)
semilogx(hx,dfdx1)
xlabel('Difference step hx'), ylabel('df/dx1'), title('Spring mass')
subplot(822)
semilogx(hx,dfdx2)
xlabel('Difference step hx'), ylabel('df/dx2'), title('Spring mass')
    %plotting of constrainst g(1)
subplot(823)
semilogx(hx,dgdx1(:,1)')
xlabel('Difference step hx'), ylabel('dg1/dx1'), title('Length constraint') 
subplot(824)
semilogx(hx,dgdx2(:,1)')
xlabel('Difference step hx'), ylabel('dg1/dx2'), title('Length constraint') 
    %plotting on constraint g(4)
subplot(825)
semilogx(hx,dgdx1(:,4)')
xlabel('Difference step hx'), ylabel('dg1/dx1'), title('Shear Stress constraint') 
subplot(826)
semilogx(hx,dgdx2(:,4)')
xlabel('Difference step hx'), ylabel('dg1/dx2'), title('Shear Stress constraint') 
%plotting on constraint g(5)
subplot(827)
semilogx(hx,dgdx1(:,5)')
xlabel('Difference step hx'), ylabel('dg1/dx1'), title('Frequency constraint') 
subplot(828)
semilogx(hx,dgdx2(:,5)')
xlabel('Difference step hx'), ylabel('dg1/dx2'), title('Frequency constraint')
