Figure & Subplot: Getting rid of needless white space

Hello, I am currently trying to find out why there is excessive white space left and right of the plots when the spacing was just fine for a single plot in the figure. Please excuse the lengthy example. I am unsure what exactly causes the strange spacing. Hopefully you can give me hint, what to look into. (as at the moment I am cropping it manually..)

btw - Loose and TightInset did not work for me yet, but it seems quite possible that I implemented them in a wrong way as the figure was either empty or cut off vertical space (instead of horizontal).

Best Regards

fig = figure();
set(fig,'color', none,'position',[100 100 1200 400]);
set(gca,'LooseInset',get(gca,'TightInset')) % my try to crop the figure

subplot(1,2,1)
p = plot(x, y1, x, y2, x, y3, x, y4); 
ylabel('label1 (unit)', 'interpreter', 'latex', 'fontsize', 20)
xlabel('label2 (unit)', 'interpreter', 'latex', 'fontsize', 20)
set(gca, 'fontsize', 20);
set(gca, 'XTick', [0:2.5:10], 'xlim', [0 10]);
set(gca, 'YTick', [0:25:100], 'ylim', [0 100]);
grid on

subplot(1,2,2)
q = plot(x2, y5, x2, y6, x2, y7, x2, y8);
ylabel('label1 (unit)', 'interpreter', 'latex', 'fontsize', 20)
xlabel('label2 (unit)', 'interpreter', 'latex', 'fontsize', 20)
set(gca, 'fontsize', 20);
set(gca, 'XTick', [0:2.5:10], 'xlim', [0 10]);
set(gca, 'YTick', [0:100:400], 'ylim', [0 400]);
grid on 

save_fig(fig, 'test');

Try FEX submission tight_subplot

Thorsten, thank you for the suggestion. I am looking into TightFig by Crozier but (as indicated by some comments there) there are difficulties because it also cuts away the axis labels. If you worked with this before, do you know if the following code snippet is the part where this would need to be reconfigured and if so, how?

    % we will move all the axes down and to the left by the amount
    % necessary to just show the bottom and leftmost axes and labels etc.
    moveleft = min(pos(:,1) - ti(:,1));

    movedown = min(pos(:,2) - ti(:,2));

    % we will also alter the height and width of the figure to just
    % encompass the topmost and rightmost axes and lables
    figwidth = max(pos(:,1) + pos(:,3) + ti(:,3) - moveleft);

    figheight = max(pos(:,2) + pos(:,4) + ti(:,4) - movedown);

tapdanceotter, I worked with tight_subplot
