GClasses::GPlotLabelSpacerLogarithmic Class Reference

Detailed Description

Similar to GPlotLabelSpacer, except for logarithmic grids. To plot in logarithmic space, set your plot window to have a range from log_e(min) to log_e(max). When you actually plot things, plot them at log_e(x), where x is the position of the thing you want to plot.

	GPlotLabelSpacerLogarithmic (double log_e_min, double log_e_max)
	Pass in the log (base e) of your min and max values. (We make you pass them in logarithmic form, so you can't use a negative min value.) More...
bool	next (double *pos, bool *primary)
	Returns true and sets *pos to the position of the next label. (You should actually plot it at log_e(*pos) in your plot window.) Returns false if there are no more (and doesn't set *pos). primary is set to true if the label is the primary label for the new scale. More...

bool GClasses::GPlotLabelSpacerLogarithmic::next	(	double *	pos,
		bool *	primary
	)

Returns true and sets *pos to the position of the next label. (You should actually plot it at log_e(*pos) in your plot window.) Returns false if there are no more (and doesn't set *pos). primary is set to true if the label is the primary label for the new scale.
