Plotting a line in matlab

Hi everyone, I am trying to draw a stright line beneath this graph for comparison evaluation but this code doesn't work for me. Any help guys.

xline = linspace(1,14,14);
xline = 1e6*xline;
yline = xline;
plot(xline,yline,'-r*','LineWidth',4);

It does work for me; it looks like multiplying xline by 1e6 makes the line disappear out of your figure because your units are in Mbps. What if you don't multiply xline by 1e6?

I do not think you need to do the 1e6*xline as the current plot you have looks to be already scaled to Mbps. Also since you're plotting a lines in two different commands you'll need to use the command 'hold on'.

such as:

figure,plot([1:10],[1:10].^2);
hold on
plot([1:10],[1:10]);

Just needed to remove the 1e6, its working now. Here it is, Thanks
