Hello There, I have been asking for help in Labview forum for a while since I am a new user. I am trying to build an application where you can filter our your desired csv file(2 variable or 3 variable data sheet) from a directory and open them in Waveform graph. I have figured out all part except the last one where I can display the data sheets into graph. I know that i have to use 'Read delimited Spreadsheet' element but I am still having hard time figuring out connecting elements with each other. If you run the attached snippet. you will see I can filter out my desired files (Which are also attached here) into 'selected file' box from 'file box' list. What I want to do is directly import the csv files from 'selected file' box to graph. If anyone have suggestions,please let me know. Thank you.

I'm guessing this is what you want. If you don't want to use the first column as X and the second as Y, make some minor changes to the Files: Double Click case. The code uses the Read From Delimited Spreadsheet with a comma set as the delimiter and reads only the first two columns, since it doesn't look like you're using any others (again, you can change this). Then it uses Index Array, with the row input unwired and the column wired with 0 and 1 to get 1D arrays of the columns. It bundles those together to form what the XY-Graph considers a "plot" (copied from detailed help): The XY graph accepts three data types for displaying multiple plots. The XY graph accepts an array of plots, where a plot is a cluster that contains an x array and a y array. This is then passed to a Build Array node, which adds it to existing data. To remove the plot in the Active Files: Double Click case, just use delete from array in the same way you already did. The other cases have the wire passed through. I deleted Timeout since you weren't ever going to see it (no timeout constant).
