signalsmith::plot::SvgDrawable Class Reference

#include <plot.h>

Detailed Description

Any drawable element.

Each element can draw to three layers: fill, stroke and label. Child elements are drawn in reverse order, so the earliest ones are drawn on top of each layer.

Copy/assign is disabled, to prevent accidental copying when you should be holding a reference.

Inherited by signalsmith::plot::HeatMap::EmbeddedHeatMap, signalsmith::plot::HeatMap::RetainedMap, signalsmith::plot::Image, signalsmith::plot::Line2D, signalsmith::plot::SvgFileDrawable, and signalsmith::plot::TextLabel.

Method Details

addChild()

void signalsmith::plot::SvgDrawable::addChild ( SvgDrawable *  child, bool  front = false  )

inline

Takes ownership of the child.

addLayoutChild()

void signalsmith::plot::SvgDrawable::addLayoutChild ( SvgDrawable *  child )

inlineprotected

These children are removed when the layout is invalidated.

clearFrames()

virtual void signalsmith::plot::SvgDrawable::clearFrames ( )

inlinevirtual

Removes all animation frames. Mostly useful if re-using the diagram for multiple animations.

Reimplemented in signalsmith::plot::Grid, and signalsmith::plot::Line2D.

loopFrame()

virtual void signalsmith::plot::SvgDrawable::loopFrame ( double  loopTime )

inlinevirtual

Sets loop time (or < 0 to disable)

Reimplemented in signalsmith::plot::Grid, and signalsmith::plot::Line2D.

toFrame()

virtual void signalsmith::plot::SvgDrawable::toFrame ( double  time, bool  clear = true  )

inlinevirtual

Creates a frame from the current stat, and optionally clears the state ready for the next frame.

The time is the start-time of the frame being created.

Two lines with a different number of frames

Reimplemented in signalsmith::plot::Grid, and signalsmith::plot::Line2D.
