Table problem ?


why doesn't this table add data one after another rather than refreshing only the same line ?

Remove the shift register and replace it with an autoindexing output tunnel.

(Try to learn about the use of shift registers. Since you are not using the left shift output, your shift registers serve no purpose. Have a look at some of the examples that ship with LabVIEW. )

Here, here, here, here and here are a few you can start with and here are some tutorial videos. You can also contact your local NI office and join one of their courses. In addition, I suggest you read the LabVIEW style guide and the LabVIEW user manual (Help>>Search the LabVIEW Bookshelf)." (©tst)

Actually, Strike that previous answer.
Since you are using the express VI that makes a table, you need to append the individual tables in a shift register. SImply use "built array" set to concatenate and enable the table always using a diagram constant.
If you want to update the table during the run of the FOR loop, place its terminal inside the loop.
Many things in your VI don't make any sense. For example why do you control the number of loop iterations with a "dwell time" control?? Why is the built table enabled only once?

this is fine but I want the previous values to stay and not be overwritten everytime a new data value is written.
Eventually I would like to see many rows of data values.
