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!

Alberto - what is the code that you are using to create your pie charts and add them to the subplots? It looks like the first and third are roughly the same size but the middle one is definitely smaller....perhaps because of the number of slices and the labels that are being applied to each slice.

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')

Alberto - I suspect the issue is with the legend. If you move the legend to the south, then the pie charts seem to be roughly the same size.

I have the same hunch as Geoff. I think the longer legend strings in the 2nd pie chart results in a small diameter.

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')
Hope this helps!
