MATLAB: Creating legend with only string

Question

x=rand(10,1);
h_x=histfit(x);
title('error');
xlabel('north (cm)')
ylabel('Number of Measurement') 
mean_x=mean(x);
h_x = legend([':mean (cm)=' num2str(mean_x)], 'Location','NorthEast');

How can I delete the blue box left near to "mean (cm)=" string in figure to display only string?

Hi, you should consider using the annotation command. Add these commands after yours :

annotation('textbox',get(h_x,'Position'),'String',['mean (cm)=' num2str(mean_x)])
legend('toggle')

The first command places the text box at the same position of the legend ; the second hides the legend.
