unsigned MakeInterval	(	double	start,
		double	stop
	)

The number for intervals to be make upon rounding the axis.

Parameters:

	start	The left most value of the axis.
	stop	The right most value of the axis.

Definition at line 68 of file AxisRounding.c.

Here is the call graph for this function:

double MakeSpacing	(	double	start,
		double	stop
	)

Returns the rounded spacing between axis interval (tic marks).

Parameters:

	start	The left most value of the axis.
	stop	The right most value of the axis.

This is a simple implemetation as such only ascending axes, where stop is greater than start, will work.

void PrintDescription	(	double	start,
		double	stop,
		double	spacing,
		unsigned	interval
	)

Sends a overview of the axis parameters to stdout.

Parameters:

	start	The left most value of the axis.
	stop	The right most value of the axis.
	spacing	The number of axis units between tic marks, as returned by the MakeSpacing() function.
	interval	The number of tic marks along the axis, including the two both ends, s returned by the MakeInterval() function.

Here is the call graph for this function:

double RoundStart	(	double	start,
		double	spacingRounded
	)

Rounded start down to the nearest multiple of the spacing.

No not need to call this directly as it is called from other functions.

Parameters:

	start	Unrounded or rounded start value.
	spacingRounded	The rounded spacing value for the axis as returned by MakeSpacing().

double RoundStop	(	double	stop,
		double	spacingRounded
	)

Rounded stop up to the nearest multiple of the spacing.

No not need to call this directly as it is called from other functions.

Parameters:

	stop	Unrounded or rounded stop value.
	spacingRounded	The rounded spacing value for the axis as returned by MakeSpacing().
