The easiest way to scale a graph is by using one of the following keys in the graph window:
| Key | Scale factor |
| = | 200 % of the current scale factor |
| + | 150 % of the current scale factor |
| - | 66 % of the current scale factor |
| _ | 50 % of the current scale factor |
| 01 | Sets the scale factor to normal (100%). |
|---|---|
| m | Sets the scale factor so that the whole graph is entirely visible. |
