Hi All, 

Could you please help me. 

I have a DAQ card with 8 single ended channels. This card has RS485 port and I have used a RS485/USB convertor to conect this card to my PC.

Now I can see the measured values of each chanel via holding registers based on below attached VI.

How can I hold and shows this data on several geraph? 

It would really appriciated if help me and complete attached VI. I am biginner in Labview.

Hi Lier,

use shift registers to hold an array of values for each signal. Then plot those arrays in your graphs.

Or use PtByPt-DataQueue for each signal…
