In this tutorial, we, Opened a Grace Project |
| 10:21 | Changed graph properties like line style, width and color |
| 10:27 | Changed properties of symbols |
| 10:31 | Adjusted global limits |
| 10:34 | Adjusted axis tick marks and grid and
Added title to the plot |
| 10:43 | As an assignment, Generate XY data set to draw a parabola. |
| 10:50 | Use integer values between -8 to +8 and plot a graph in Grace. |
| 10:57 | Change color, add title and symbol. |
| 11:02 | The completed assignment should look similar to this. |
