You can create a figure with the Visible property set to 'off'.
f=figure('Visible','off');
X=randi(15,1,100);
histogram(X,'Parent',f);
saveas(f,'test.png')
close(f)

Thanks!! it's right :) Now I have this problem: i want to save the histogram in a certain folder,but saveas() returns error. The code is: saveas(f,filename); where, f is the histogram while filename is a character vector (''C:\Users\Annagrazia\Desktop\Progetto\Istogrammi\Istogramma_Immagine_01.tif'). The error is: 'Invalid Handle'. How can i solve this?

f is not the histogram, f is the handle to the figure (which in this case contains a histogram). That might seem like a nitpicky point, but it probably points to where your bug is.
I tried to use print instead of saveas, and I use this command: print(percorso,'-dtiff'); where "percorso" is the path of the folder where the image has to be saved. But it returns this error:
Cannot create output file 'C:\Users\Annagrazia\Desktop\Progetto\Cartella\Istogramma_Immagine_01.tif'. Error in print (line 71) pj = name( pj );
How can I change the path where print save the figure? Thanks for helping!!

I don't see any reason why that would fail. What is the complete code you're using? (please use the {}Code button to format your code)
