void SetLabelSpace (axis, factor) FNTPLT.C Level 2
int axis The axis for which spacing is being set. axis can be one of these constants (defined in GRAPHIC.H): X_AXIS, Y_AXIS, Z_AXIS.
float factor The multiplication factor for the gap between the axis labels and the axis (or outward-pointing tick marks) for the specified axis. The default spacing is 60 pixels in 8192 space, and is restored at the start of each plot. 
SetLabelSpace() sets the spacing between the axis labels (numbers or strings) and the axis axis itself. If the tick marks point outwards, this gap is between the labels and the tick marks. For example, to double the space between the x axis and the x axis tick labels call SetLabelSpace(X_AXIS, 2.f).
