Hi all!

I am trying to plot pie charts within a subplot. However, I don't know why the charts all come with different sizes. I have attached a figure as an example.

Is there a way to resize all charts so that they all have the same dimension?

Thank you!

Hi Geoff, thanks for your reply. Please find the code below.

Tha chart in the middle is definitely smaller but also the one on the right is slightly bigger.

figure(2)
subplot(1,3,1)
par1=[1319 8513	12767 8074 789];
labels={'4%','27%','41%','26%','3%'};
p1=pie(par1,labels);
set(findobj(p1,'type','text'),'FontSize',17,'FontName','Arial')
title('NUMBER OF STORIES','FontSize',20,'FontName','Arial')
legend({'1 Story',' Stories','3 Stories','4 Stories','5 Stories'},'Location','eastoutside','FontSize',17,'FontName','Arial')
subplot(1,3,2)
par2=[17787 4834 3427 975 1174 2041 967];
labels={'57%','15%','11%','3%','4%','6%','3%'};
p2=pie(par2,labels);
set(findobj(p2,'type','text'),'FontSize',17,'FontName','Arial')
title('CONSTRUCTION PERIOD','FontSize',20,'FontName','Arial')
legend({'< 1860','1861-1919','1919-1945','1946-1961','1962-1971','1972-1975','1976-1981'},'Location','eastoutside','FontSize',17,'FontName','Arial')
subplot(1,3,3)
par3=[13551 6296];
labels={'68%','32%'};
p3=pie(par3,labels);
set(findobj(p3,'type','text'),'FontSize',17,'FontName','Arial')
title('RING BEAMS AND TIE RODS','FontSize',20,'FontName','Arial')
legend({'Present','Absent'},'Location','eastoutside','FontSize',17,'FontName','Arial')

Thank you Geoff and Adam!

Unfortunately, I have to plot other charts with many values, so the legend at the bottom causes the same issues....

I solved it by plotting each chart separately and then merging them with an imaging software. It is slow but it works!

I haven't tried it but this problem might not persist if you used tiledlayout rather than subplots.

Hi Alberto,

As @Adam Danz has rightly pointed out tiledlayout function will help you out and also as you mentioned you have other charts as well, you can utilize the 'flow' option in case the number of charts is unknown.

Your code modified using tiledlayout:

figure(2)
% subplot(1,3,1)
tiledlayout(1,3);
% Tile 1
nexttile;
par1=[1319 8513	12767 8074 789];
labels={'4%','27%','41%','26%','3%'};
p1=pie(par1,labels);
set(findobj(p1,'type','text'),'FontSize',17,'FontName','Arial')
title('NUMBER OF STORIES','FontSize',20,'FontName','Arial')
legend({'1 Story',' Stories','3 Stories','4 Stories','5 Stories'},'Location','eastoutside','FontSize',17,'FontName','Arial')
% Tile 2
% subplot(1,3,2)
nexttile;
par2=[17787 4834 3427 975 1174 2041 967];
labels={'57%','15%','11%','3%','4%','6%','3%'};
p2=pie(par2,labels);
set(findobj(p2,'type','text'),'FontSize',17,'FontName','Arial')
title('CONSTRUCTION PERIOD','FontSize',20,'FontName','Arial')
legend({'< 1860','1861-1919','1919-1945','1946-1961','1962-1971','1972-1975','1976-1981'},'Location','eastoutside','FontSize',17,'FontName','Arial')
% Tile 3
% subplot(1,3,3)
nexttile;
par3=[13551 6296];
labels={'68%','32%'};
p3=pie(par3,labels);
set(findobj(p3,'type','text'),'FontSize',17,'FontName','Arial')
title('RING BEAMS AND TIE RODS','FontSize',20,'FontName','Arial')
legend({'Present','Absent'},'Location','eastoutside','FontSize',17,'FontName','Arial')
