how to change the linewidth of one line of the figure generated from using compare function?

Hi Matlab community! I Have a graph of the measured vs predicted values created with compare function. I wanna highlight the measured values with a linewidth of 1 and leave the others with a linewidth of 0.5, how can I do that? I tried to use the command line and set and it didn't work. Thanks for your help

Hi Gina,

See accessing object properties using dot notation. I took the first example from the documentation for compare:

load iddata1 z1;
sys = ssest(z1,3);
prediction_horizon = 10;
compare(z1,sys,prediction_horizon);

and I changed the width of one line with the following command:

hFig = gcf;
hFig.Children(4).Children(1).Children.LineWidth = 1;
