#include <heatmap.h>

Detailed Description

Pixel-based heat-map.

You create this separately, and then attach to a Figure or Plot later, or save directly to PNG.

addTo()

Plot2D& signalsmith::plot::HeatMap::addTo ( Grid &  grid, double  width, double  height, double  scaleWidth = 15  )

inline

Adds data and scale plots to a grid (e.g. a figure), returning the data plot.

copyTo()

template<class Drawable , class... Args>

auto signalsmith::plot::HeatMap::copyTo ( Drawable &  drawable, Args &&...  args  ) -> decltype(this->addTo(drawable, std::forward<Args>(args)...))

inline

Makes a retained copy of the map, then calls .addTo(...)
