time table

Hi, I need to plot multiple data and put it into table with timestamp, but I found each data follow one timestamp, if the time column is same, how can I remove the redundant time column ( just show one time column)?

You could use the Delete From Array function to delete the first column:

Looks like Steve beat me on this one

A quick fix would be to use "delete from array" function:

You could do this without the express Vi.

Thanks for the above reply. Furthermore question, if i need to delete column 1 and 3. Any simple method other than add a new "delete from array" block.

And how can I save the edited data in the tdms file (actually I am confused with the match of terminal type errors). Thank you!

You can use Write to Measurement File Express VI, Storage VIs or TDMS primitive VIs in LabVIEW to save data to TDMS files.

Thanks for your reply. 
Error found when I connect the array w/ subset deleted pin to the signal of write to measurement file block, so what is the solution to solve the error?

[YongqingYe]

Write to Measurement Express VI doesn't accpet the table data type as the input. I would recommend convert the table to 2D array or waveform and then wire it to the Express VI.

Does the input pin for data block is 2D array? I am still confused with the terminal conversion, anyone can illustrate that or provide a vi work example, thank you.

You can wire a 2D double array to the input, and to see what will happen 🙂
