12 To Do

• Planned new renderers

  • 2D kernel density estimator

  • 3D kernel density estimator

  • 2D implicit curve

  • 3D implicit surface

  • 3D decorations: labeled points, axes, grids

• Possible new renderers

  • R × R -> R parametric (turn into 3D implicit surface by solving for minimum distance?)

  • 3D vector field

  • Head-to-tail vector fields

• Minor fixes

  • Subdivide nonlinearly transformed 3D lines/polygons (port from 2d-plot-area%)

• Minor enhancements

  • Better depth sorting (possibly split intersecting polygons; look into BSP tree)

  • Legend entries have minimum sizes

  • Log-scale tick functions (i.e. major ticks are 10^0, 10^1, 10^2, ...)

  • Label contour heights on the contour lines

  • 3D support for exact rational functions (i.e. polynomial at [big..big+ε])

  • Join 2D contour lines

  • More appearance options (i.e. draw 2D tick labels on right/top)

  • Manually exclude discontinuous points from function renderers: allow values (hole p1 p2), (left-hole p1 p2), (right-hole p1 p2)

  • histogram-list to plot multiple histograms without manually calculating #:x-min
