                          gdouble *max);

Gets the range of a color axis.

Parameters

axis	A color axis.
min	Location to store the range maximum (or NULL).
max	Location to store the range minimum (or NULL).

gwy_color_axis_set_range ()

void
gwy_color_axis_set_range (GwyColorAxis *axis,
                          gdouble min,
                          gdouble max);

Sets the range of a color axis.

Parameters

axis	A color axis.
min	The range minimum.
max	The range maximum.

gwy_color_axis_get_si_unit ()

GwySIUnit *
gwy_color_axis_get_si_unit (GwyColorAxis *axis);

Gets the SI unit a color axis displays.

Parameters

axis

A color axis.

Returns

The SI unit.

gwy_color_axis_set_si_unit ()

void
gwy_color_axis_set_si_unit (GwyColorAxis *axis,
                            GwySIUnit *unit);

Sets the SI unit a color axis displays.

Parameters

axis	A color axis.
unit	A SI unit to display next to minimum and maximum value.

gwy_color_axis_set_gradient ()

void
gwy_color_axis_set_gradient (GwyColorAxis *axis,
                             const gchar *gradient);

Sets the color gradient a color axis should use.

Parameters

axis	A color axis.
gradient	Name of gradient axis should use. It should exist.

gwy_color_axis_get_gradient ()

const gchar *
gwy_color_axis_get_gradient (GwyColorAxis *axis);

Gets the color gradient a color axis uses.

Parameters

axis

A color axis.

Returns

The color gradient.

gwy_color_axis_get_ticks_style ()

GwyTicksStyle
gwy_color_axis_get_ticks_style (GwyColorAxis *axis);

Gets ticks style of a color axis.

Parameters

axis

A color axis.

Returns

The ticks style.

gwy_color_axis_set_ticks_style ()

void
gwy_color_axis_set_ticks_style (GwyColorAxis *axis,
                                GwyTicksStyle ticks_style);

Sets the ticks style of a color axis.

Parameters

axis	A color axis.
ticks_style	The ticks style to use.

gwy_color_axis_get_labels_visible ()

gboolean
gwy_color_axis_get_labels_visible (GwyColorAxis *axis);

Gets the visibility of labels of a color axis.

Parameters

axis

A color axis.

Returns

TRUE if labels are displayed, FALSE if they are omitted.

gwy_color_axis_set_labels_visible ()

void
gwy_color_axis_set_labels_visible (GwyColorAxis *axis,
                                   gboolean labels_visible);

Sets the visibility of labels of a color axis.

Parameters

axis	A color axis.
labels_visible	TRUE to display labels with minimum and maximum values, FALSE to display no labels.

gwy_color_axis_set_tick_map_func ()

void
gwy_color_axis_set_tick_map_func (GwyColorAxis *axis,
                                  GwyColorAxisMapFunc func,
                                  gpointer user_data);

Set the tick mapping function for a color axis.

The axis calculates tick positions as for the linear axis and then places them non-linearly using func . Hence a mapping function should be used with ticks mode GWY_TICKS_STYLE_UNLABELLED because minimum tick spacing is not guaranteed.

Parameters

axis	A color axis.
func	Tick mapping function.
user_data	Data to pass to func .

Since: 2.39
