Hi Ming86,

1. What hardware are you using?  Is it made by National Instruments?
   
2. What function are you using to acquire the data?
3. What kind of data is it (analog/digital)?

In a loop, you should be able to make your matrix into a 1D array.  For a digital sample, consider setting ChannelLineGroupingEnumeration to OneChannelForAllLines to acquire the data in a single channel.  Also, notice the MultiChannelReader Class for each type of input (analog, digital, counter, etc.).

1)I am using a AMTI force plate with NI DAQ

2)CWAI1.Configure

CWAI1.Start

CWAI.Stop

For acquire data from graph i use under the CWA1_Acquiredate function

i use CWGraph1.ChartY ScaledData

3)analog

How can i get the numerical number for all the six channel in the graph?

How do i apply matrix in VB to calibrate the force plate?

Hi Ming86,

Please see the following tutorial for this information:

Notice especially sections 6 and 7.

Hi Ming86,

Here are some more references:

For more info, please do a search for "measurement studio visual basic" at ni.com.  Also, there should be help in the menus of Visual Basic.
