First, your file is a tab-delimited text file, not an Excel format file.  You just put the .xls extension on it so that the OS would ask Excel to open it.

Second, What have you tried?

You can read the file as a text file and then use string functions to convert to numeric values to plot.  Or use the Read fromSpreadsheet File VI with the String mode selected.  Convert the resulting string array and plot.

Have a little patience. You've also not shown or explained what the difficulty is. Are you not able to read the file, format the data, or something else. Post what you have written so far.

i have no trouble plotting the data actually, my main problem is setting the x-axis of the graph as the date/time which i have written to the first two column of the spreadsheet

Context click on the x-axis and select absolute or relative time as the format.  This is probbaly also available as a property.
