Reading a binary file

[Blackj]

I am writing a program that logs data from a DAQ card. Currently the program plots the data from the DAQ on a graph while it is running at the same time the data is logged to a binary file. I am using the Read Binary File example vi to read the logged data back while the data appears to be the same as when it was logged the values on the y axis is wrong. You have to zoom way in to see the waveform and the array just lists all the elements as zero, any ideas on whats going wrong and how to fix it?
Thanks

Make sure that you have autoscale turned on your graph. There is a
setting for both the x and y scale. You can also verify the data
being written to the graph by right clicking on the wire going to it
and create >> indicator . This might help determine the zero
behavior of your array.
