I'm guessing they are as different messages? If so you will need to join them together you can either use the join node or context values so that they are in the same message.

The cookbook has some useful recipes. This one may be useful to you

I have checked into the flow , it gives the output as below

,

In my application, all the message data should be sent at a time & then a string should be displayed on dashboard.Because in my flow earlier attached , the byte data coming is from RFID ..all bytes are read in single shot & then has to be displayed as string.....Hope this is possible

The flow that you posted shows that two of the inputs (1 & 3) were from numerical input nodes on the dashboard.
If you are saying now that they are in one message you can join them easily eg

msg.payload = "message one is:"+msg.one+" message two is:"+msg.two
