Hello

I want to display mean and std with some text in a text box on a plot.

For now, I don't know how to relate the values, so I just write the code like this.

I put values one by one after calculating mean and std.

is there any way to take values automatically to the annotation?

Thank you in advance.

[xyz, mn, st] = nmea(stop);
% mn = mean
% st = std
plot(1:length(stop),xyz);
xlabel('time [sec]');
ylabel('position [m]')
legend('x','y','z');
str = {'mean_x = -3035497.2060m';'mean_y = 4047836.2866m';'mean_z = 3896386.6521m';'std_x = 1.7452m'; 'std_y = 1.1734m'; 'std_z = 1.9720m'};
dim = [0.53 0.27 .2 .2];
annotation('textbox',dim,'String',str,'FitBoxToText','on');
