- Function:
**title-top***title subtitle* - Function:
**title-top***title* Puts a

`title`line and an optional`subtitle`line above the`graphrect`

.

- Function:
**title-bottom***title subtitle* - Function:
**title-bottom***title* Puts a

`title`line and an optional`subtitle`line below the`graphrect`

.

- Variable:
**topedge** - Variable:
**bottomedge** -
These edge coordinates of

`graphrect`

are suitable for passing as the first argument to`rule-horizontal`

.

- Variable:
**leftedge** - Variable:
**rightedge** -
These edge coordinates of

`graphrect`

are suitable for passing as the first argument to`rule-vertical`

.

- Function:
**set-margin-templates***left right* -
The margin-templates are strings whose displayed width is used to reserve space for the left and right side numerical legends. The default values are "-.0123456789".

- Function:
**rule-vertical***x-coord text tick-width* -
Draws a vertical ruler with X coordinate

`x-coord`and labeled with string`text`. If`tick-width`is positive, then the ticks are`tick-width`long on the right side of`x-coord`; and`text`and numeric legends are on the left. If`tick-width`is negative, then the ticks are -`tick-width`long on the left side of`x-coord`; and`text`and numeric legends are on the right.

- Function:
**rule-horizontal***y-coord text tick-height* -
Draws a horizontal ruler with Y coordinate

`y-coord`and labeled with string`text`. If`tick-height`is positive, then the ticks are`tick-height`long on the top side of`y-coord`; and`text`and numeric legends are on the bottom. If`tick-height`is negative, then the ticks are -`tick-height`long on the bottom side of`y-coord`; and`text`and numeric legends are on the top.

- Function:
**y-axis** -
Draws the y-axis.

- Function:
**x-axis** -
Draws the x-axis.

- Function:
**grid-verticals** -
Draws vertical lines through

`graphrect`

at each tick on the vertical ruler.

- Function:
**grid-horizontals** -
Draws horizontal lines through

`graphrect`

at each tick on the horizontal ruler.
