Using Digital Trigger channel

Hello,

 

I have PXI 6363 card and use LabVIEW 2012 version.

I have 10 analog and 10 digital channels. I need to read data on these channels with respect to time. I have a digital trigger. Only after I recieve the trigger, I need to start to read the analog and digital data and plot on the graph. If I use the DAQmx Start.vi before the while loop, then I get unwanted extra data. How to configure the channels so that I get the precise data from the digital trigger point. (I use DAQmx Trigger.vi)

 

Thanks.
