How can I change the size of my figure or the title position so that the title does not overlap my figure anymore?

Hello,

I am trying to reduce the size of my figure or to upper the position of my title so that the title doesn't overlap the figure.

(Please see attached figure)

But whenever I try to change the figure or the title position nothing changes on my figure, what am I doing wrong??

I tried both % command below both is doesn't change anything on my figure...

figure(3);
hold on;
%figure('Position',[0.1 0.1 0.4 0.4]);
w=worldmap([20 90],[-180 180]);
p=findobj(w,'Tag','Parallel');
m=findobj(w,'Tag','Meridian');
p.LineWidth=1.5; 
m.LineWidth=1.5;
pcolorm(latMat,lonMat,a1);
colormap jet; 
cb=colorbar; 
set(cb, 'Position',[0.75 0.15 0.03 0.78]); 
geoshow('landareas.shp','FaceColor',"none",'LineWidth',1);
title('Task 1.7: PC1');
%set(get(gca,'title'),'Position',[1 1 1]);
hold off;

Thanks
