How do I get a specific point coordinate reading out of a plot?

The graph is plotted by:

z=1; for m=-10:2.5:30 for n=1:1000 [answer2(n,z),SignalLevel2(n,z)]=detectmodel2(db2amp(m),-5,5); end % of if z=z+1; end % of for

figure plot([-10:2.5:30],sum(answer2)./10,'k-x'); xlabel('Signal Level [dB]'); ylabel('Percent Detected');

Thanks, m

In your figure, click menu Tools->Data Cursor, and then click any point on the curve.
