I am using the following command to read the data from a text file with two variable as:

```

0 4
1 5
3 7

```

.. so on.

```
exec xgraph data.txt -t "K vs Pow data" -x "Value of K" -y "Value of Pow" -m 

```

But my xgraph is not showing any points. All I can see is both the axis and legend on the right side. Is there a option I have to add to start showing the line graph or if possible the points on the grid.
