If you drag along at the level of the tick labels, you can change the endpoints of the scale. The small button at the upper right of each slider converts it to and from a keyboard-input mode. In that mode, you can also change the scale endpoints and number of digits displayed. A simple graphics facility is available from the Options menu. Enter the variables for the x and y axes, and the range of values for the x variable.
More information is available through the graphics dialog's help menu.
