See if this does what you want:
figure(1)
plot(myData)
hold on
plot(sample)
hold off

It actually did work. Your ‘sample’ is a single data point plotted at (0,1000). Your ‘myData’ vector are a sequence of random floating-point numbers on the interval (0,1). The plot scales them linearly in both axes, so the random vector appears as a line on the x-axis.
To see this, plot them logarithmically:
sample = 1000;
myData = rand(1,sample);
figure(1)
semilogy(myData, '-r')
hold on
plot(sample, 'bp')
hold off
