Using these data with the code I provided in my Answer to your previous Question How can I insert a detail in the peak of the curve ?
The ‘V Vectors’ , ‘V_86’, ’V_89’, ‘V_91’, ‘V_92’, ‘V_95’, are provided in ‘Mallouli Marwa V Vectors.mat’, attached.
This Code —
omega = 125.6:0.1:502.4;
freq = omega./(2*pi);
figure
ax1 = axes('Position',[0.2 0.1 0.7 0.8]);
ax2 = axes('Position',[0.25 0.65 0.15 0.2]);
plot(ax1, freq,V_86,'g', freq,V_89,'k', freq,V_91,'m',freq,V_92,'c',freq,V_95,'b','LineWidth',2)
legend(ax1, 'FVF = 0.86','FVF = 0.89','FVF = 0.91','FVF = 0.92','FVF = 0.95');
xlabel(ax1,'Frequency [Hz]');
ylabel(ax1,'|Voltage FRF| [V/g]');
Lv = (freq>=45) & (freq<=52);
plot(ax2, freq(Lv),V_86(Lv),'g', freq(Lv),V_89(Lv),'k', freq(Lv),V_91(Lv),'m',freq(Lv),V_92(Lv),'c',freq(Lv),V_95(Lv),'b','LineWidth',2)
ax2.XTickLabel = [];
ax2.YTickLabel = [];
annotation('arrow',[0.37 0.56], [0.8 0.8])
Produces This Plot —
Experiment with my code to get different results.

How can I broaden the scale of the detail figure to make it more visible ?

Experiment with the Position limits:
ax2 = axes('Position',[0.25 0.65 0.15 0.20]);
Remember that they are respectively [left bottom width height]. If you want to increase the width, increase elment 3, perhaps:
ax2 = axes('Position',[0.25 0.65 0.20 0.20]);
I did not test that to see what it looked like. It may also be necessary to adjust the annotation arrow.

My prefered tool for this is: on-figure-magnifier - at the moment, my preferences vary since you can find a range of similar tools if you search for "magnify" on the file exchange.

See my demos that allow you to put insets of images or plots into other images or plots. When you plot the inset, change xlim and ylim to zoom in on the part your want to enlarge.
