| 06:31 | Notice the two column data format. |
| 06:35 | First column is x data and second column is y data. |
| 06:41 | The data values are tab separated. |
| 06:45 | Close the file and go back to grace window. |
| 06:49 | Next, we will load data to plot a graph. |
| 06:53 | Notice that, the axis limits are from zero to one for both axes. |
| 07:00 | Next, let’s load the data file to make a XY plot. |
| 07:05 | Click on Data tab, Import and select ASCII format. |

| 08:01 | Then, X and Y axis range automatically adjust to lower and higher values of data. |
| 08:09 | Click on OK button to load the data. |
| 08:13 | Click on Cancel to close the dialog box. |
| 08:17 | We can see a graph representing the data. |
