i have a graph made in matlab with plot function but the title or legend is not shown because vertically it is very large, how can I make it smaller to be able to visualize the entire graph. Aditionally I have two x axes, one in bottom and the other at the top.
This is the script
%graficas de la biblioteca central
a=xlsread('Libro1.xlsx','H2:H96');
b=xlsread('Libro2.xlsx','AP3:AP171');
c = datenum(fechamec,'dd-mmm-yyyy HH:MM:SS');
figure(1)
plot(c,b,'r')
xlabel('Fecha: año 2020')
ylabel('Temperatura [°C]')
datetick('x', 'dd-mmm')
xtickangle(20)
hold on
d=xlsread('Libro2.xlsx','F3:F171');
e=xlsread('Libro2.xlsx','Y3:Y171');
f=xlsread('Libro2.xlsx','AH3:AH171');
g=xlsread('Libro2.xlsx','AX3:AX171');
h=xlsread('Libro2.xlsx','BG3:BG171');
plot(c,d,'g')
plot(c,e,'m')
plot(c,f,'c')
plot(c,g,'color',[0.9290 0.6940 0.1250])
plot(c,h,'color',[0 0.4470 0.7410])
legend ('T[°C] 4 ventanas cerradas y puerta cerrada','T[°C] 4 ventanas abiertas y puerta abierta','T[°C] 4 ventanas abiertas y puerta cerrada','T[°C] 2 ventanas abiertas y puerta abierta','T[°C] 4 ventanas cerradas y puerta abierta','T[°C] 2 ventanas abiertas y puerta cerrada')
hold off
grid on
ax1 = gca; % este eje deje activo
ax1_pos = ax1.Position; % esto es para ver la posición con respecto al primer eje
ax2 = axes('Position',ax1_pos,'XAxisLocation','top','YAxisLocation','right','Color','none');
x2 = datenum(fechamec,'dd-mmm-yyyy HH:MM:SS');
eje=[0:168];
y2=c'*0+100;
line(x2,y2,'Parent',ax2,'Color','b');
datetick('x', 'HH:MM');
title('Temperatura del Aire Interior en el aula M101');
xlabel('Horas[H]')
ylim([15 40]);
yticks([15 20 25 30 35 40]);
xlim([731222 731229]);
xticks([731222:0.5:731229]);

Hi, could you help me? I need to modify the size of the figure because the tittle isn't showing in my simulation.

Try something like this:
figure
plot( ... )
title( ... )
legend( ... )
pos = get(gcf, 'Position')
set(gcf, 'Position',pos+[0 -600 0 600])
Note that it uses the figure 'Position' property, rather than the axes 'Position' property to stretch the figure vertically. Experiment with different values for the vector elements to get different results.

Experiment with the same idea, however using gca instead of gcf. The scale changes, so perhaps:
pos = get(gca, 'Position')
set(gca, 'Position',pos+[0 -pos(2)*0.5 0 pos(2)*0.5])
Or something similar.
