I'm trying to perform a simple task: export data into a '.dat' file, then importing that file onto Mathematica on another terminal, and then plotting the list. But I keep getting the same blank plot!

For example, my export command looks like:


Then I use:

DATA = Import["Data1.dat", "Table"];

x = DATA[[All, 1]];
y = DATA[[All, 2]];

data = Transpose[{x, y}];

ListPlot[data, Mesh -> All]

Is there a subtlety in what I export?

  • $\begingroup$ Maybe try restarting with a new Kernel? Another thing you can try is to create a small table of data with the same shape as your large data file and check to see if the format is correct. $\endgroup$ – Dunlop Sep 27 '19 at 11:13

Numbers in your file are written as strings.

data = Import["Data1.dat", "Table"];

ListPlot[ToExpression@data, PlotRange -> All]
