Simulated Signal will not expand to fit the graph

[Iamthetest]

I am trying to Merge 4 signals over each other.  The signals are as follows:

y = -40t**2 + 8t
y = -80t**2 + 8t
60 Hz with an amplitude = .4
60 Hz white noise with an amplitude = .01

The problem is that I cant get signals 3 and 4 to expand past .1 (on the x-axis).  My professor is less than helpful and I dont know what to do.  Ive tried to format the x-axis to no avail.  Ive looked through many helpful tutorials as well...Im just stuck on the last few things.  Hopefully the attatched VI will assist in my question.

Thanks,
Zach.

Select Properties for the two simulate signal functions and deselect the automatic number of samples and change the number of samples. You should notice that with automatic enabled, the number of samples is 1/10 of your sample rate - giving you only .1 sec of samples. You might also want to right click on the graph for the third problem and select 'Ignore Time Stamp' if you want 0 to .2 on the x axis.

Thanks Dennis.  That cleared up a lot for me.  My VI looks loads better now.
