Customizing Axis

In order to customize the axis, click on the button in toolbar. That will switch the lower left panel from Draw Attributes to Axis Setup as shown below:

You may now change axis-related values such as Range, Axis Length, Number of Divisions and Unit Values.

For example, changing the x range to -5,+15 will result in the following:

If you prefer the the length of the x-axis does not change after applying the range, then make sure that Fix axis length is checked before changing the range as shown below.

Play with other attributes of axis and see the results.
