DEFAULT IMPLEMENTATION.

virtual void casa::PlotCanvas::setSelectLine	(	const casacore::String &	color,
		PlotLine::Style	style = `PlotLine::SOLID`,
		double	width = `1.0`
	)

virtual

virtual void casa::PlotCanvas::setSelectLineShown ( bool shown = true )

pure virtual

Sets whether a line is shown for the selection tool.

virtual void casa::PlotCanvas::setTitle ( const casacore::String & title )

pure virtual

Sets the text of the canvas title to the given.

Setting the title to an empty string should remove the title from the canvas.

virtual void casa::PlotCanvas::setTitleFont ( const PlotFont & font )

pure virtual

Set the font of the canvas title to the given.

virtual void casa::PlotCanvas::setTitleFont ( const PlotFontPtr font )

virtual

Convenience method for setting title font.

DEFAULT IMPLEMENTATION.

virtual void casa::PlotCanvas::show ( )

pure virtual

virtual void casa::PlotCanvas::showAllAxes ( bool show )

virtual

Convenience method for showing/hiding all four axes at once.

DEFAULT IMPLEMENTATION.

virtual void casa::PlotCanvas::showAxes ( PlotAxisBitset axes )

pure virtual

Shows/Hides axes based on the given bitset, which should be a bitwise-or of PlotAxis values.

virtual void casa::PlotCanvas::showAxes	(	PlotAxis	xAxis,
		PlotAxis	yAxis,
		bool	show = `true`
	)

virtual

Convenience method for showing/hiding two axes at once.

DEFAULT IMPLEMENTATION.

virtual void casa::PlotCanvas::showAxis	(	PlotAxis	axis,
		bool	show = `true`
	)

virtual

Shows/hides the given axis.

DEFAULT IMPLEMENTATION.

virtual void casa::PlotCanvas::showCartesianAxes	(	bool	show = `true`,
		bool	hideNormal = `true`
	)

virtual

virtual void casa::PlotCanvas::showCartesianAxis	(	PlotAxis	mirrorAxis,
		PlotAxis	secondaryAxis,
		bool	show = `true`,
		bool	hideNormalAxis = `true`
	)

pure virtual

Show or hide the given Cartesian axis.

A Cartesian axis is different from a normal axis in that it is inside the graph, corresponding to the (0,0) location of the plot(s), rather than outside the graph. The secondary axis is the axis at which the mirrored axis will be placed at the 0 value of. For example, to show the Cartesian X_BOTTOM axis you'd likely want to mirror the axis at Y_LEFT = 0, so that would be the secondary axis. If hideNormalAxis is true, it is equivalent to showAxis(mirrorAxis, !hideNormalAxis).

virtual void casa::PlotCanvas::showCartesianAxis	(	PlotAxis	mirrorAxis,
		bool	show = `true`,
		bool	hideNormalAxis = `true`
	)

virtual

Convenience methods for most common Cartesian axes cases.

DEFAULT IMPLEMENTATION.

virtual void casa::PlotCanvas::showColorBar	(	bool	show = `true`,
		PlotAxis	axis = `Y_RIGHT`
	)

pure virtual

Shows/hides a color bar is shown on the given axis.

(See colorBarShown().)

virtual void casa::PlotCanvas::showGrid	(	bool	xMajor,
		bool	xMinor,
		bool	yMajor,
		bool	yMinor
	)

pure virtual

Sets whether the grid is shown, for each of the given line groups.

virtual void casa::PlotCanvas::showGrid ( bool showAll = true )

virtual

Convenience methods for showing/hiding the grid.

DEFAULT IMPLEMENTATION.

virtual void casa::PlotCanvas::showGridMajor ( bool show = true )

virtual

virtual void casa::PlotCanvas::showGridMinor ( bool show = true )

virtual

virtual void casa::PlotCanvas::showGridXMajor ( bool s = true )

virtual

virtual void casa::PlotCanvas::showGridXMinor ( bool s = true )

virtual

virtual void casa::PlotCanvas::showGridYMajor ( bool s = true )

virtual

virtual void casa::PlotCanvas::showGridYMinor ( bool s = true )

virtual

virtual void casa::PlotCanvas::showLegend	(	bool	on = `true`,
		LegendPosition	position = `EXT_BOTTOM`
	)

pure virtual

Show/hide the legend.

If on is true, show the legend in the given position.

virtual PlotAxisBitset casa::PlotCanvas::shownAxes ( ) const

pure virtual

Axes Methods //.

Returns a bitwise-or of PlotAxis values corresponding to which sides are shown

virtual std::pair<int, int> casa::PlotCanvas::size ( ) const

pure virtual

GUI Methods //.

Returns the canvas size in pixels (width x height).

virtual PlotStandardMouseToolGroupPtr casa::PlotCanvas::standardMouseTools ( )

virtual

Returns the standard mouse tools associated with this canvas.

If none is associated, creates and associates one that is non-active. DEFAULT IMPLEMENTATION.

virtual std::vector<double> casa::PlotCanvas::textWidthHeightDescent	(	const casacore::String &	text,
		PlotFontPtr	font
	)		const

pure virtual

Returns the width, height, and descent for the given text in the given font.

Note: this was put into place for use in a matplotlib backend, but probably doesn't have much use outside that.

virtual casacore::String casa::PlotCanvas::title ( ) const

pure virtual

Returns the text of the canvas title, or an empty casacore::String if none is shown.

The title is shown above the plotting area.

virtual PlotFontPtr casa::PlotCanvas::titleFont ( ) const

pure virtual

Returns a copy of the font used for the canvas title.

If no title is shown this behavior is undefined.
