Syntax

[C/C++:]
void ggDrawColourScale(float xy, float width);

[F90:]
subroutine ggDrawColourScale(xy, width)

real, intent(in) :: xy, width

Arguments

xy
Position of start/bottom of colour scale bar (in space coordinates)

width
Width/height of colour scale bar (in space coordinates)

Description

The routine ggDrawColourScale() displays a graduated colour bar with respect to the current colour scale setting as set by ggSetColourScale(). The bar will extend over the range of graphical values set by ggSetColourScale() and be drawn in the direction of the axis also set by this routine. The position xy, and width, are therefore measured in the other direction, such that if the colour scale is set for the X axis, xy is the Y coordinate of the bottom of the colour bar and width, its height.
