Waveform chart extremely fast in the x axis

[kepham]

Hello, I am getting a horizontal line as the waveform chart is running at fast speeds. Is there a way I can enlarge the scale so that it will display more fine, instead of fast horizontal lines that are difficult to read? In the picture is what I am dealing with... I am using the cRIOMain2 to send data via shared variables to the SingleTunnel2 vi.

This would be the intended goal...

Charts plot as fast as you send data to them.  If you are sampling at 1 kHz, you need to plot 1000 (new) points per second (which is about 20 times faster than you can "see" the data).  You can (a) acquire data at a slower rate, or (b) not plot every point.  There are two "easy" ways to do the latter -- plot every Nth (i.e. 20th) point, or average (say 20 points at a time) and plot the averages.
