What is supported

A quick list of what fastplot implements. The guide pages explain each area in more detail.

Figures and output
Creating figure, subplots, subplot_mosaic, add_subplot (with GridSpec), add_axes
Layout subplots_adjust, tight_layout, suptitle, fig.text, fig.legend
Saving savefig to PNG, JPEG, WebP and other Pillow formats; PDF, SVG and EPS holding the drawn picture; bbox_inches='tight', dpi, transparent
Arrays fig.draw() returns an RGBA numpy array
Colorbars fig.colorbar with matplotlib's placement, ticks, format and extensions

Maps
Projections PlateCarree, Mercator, Miller, LambertConformal, AlbersEqualArea, Stereographic, NorthPolarStereo, SouthPolarStereo, Orthographic, LambertAzimuthalEqualArea, Robinson, RotatedPole
Area set_extent, set_global, or fitted to the data
Fields pcolormesh (nearest, flat, gouraud), imshow, contourf, contour, clabel, on 1-D axes or 2-D curvilinear grids
Vectors barbs, quiver, quiverkey, streamplot
Features coastlines, add_feature with COASTLINE, BORDERS, STATES, LAKES, LAND, OCEAN, RIVERS, COUNTIES, NaturalEarthFeature
Gridlines gridlines(draw_labels=True), xlocs, ylocs

Areas and bars fill_between, fill_betweenx, stackplot, axhspan, axvspan, bar, barh, bar_label, hist
Fields and vectors pcolormesh, imshow, contourf, contour, clabel, quiver, barbs, streamplot
Triangles tricontourf, tricontour, tripcolor, triplot; fastplot.tri with Triangulation, TriFinder, LinearTriInterpolator, CubicTriInterpolator, UniformTriRefiner, TriAnalyzer
Shapes and text add_patch (fastplot.patches), text, annotate, legend, hatching, text outlines with fastplot.patheffects (withStroke, Stroke, Normal)
Scales linear, log, symlog, logit, function; dates; categories
Axes twinx, twiny, shared axes, inversion, aspect, margins, spines, tick_params, minor ticks, grids
Polar projection='polar', full circle, log radius

Meteorology
Skew-T fastplot.skewt.SkewT with MetPy's methods
Hodograph fastplot.skewt.Hodograph with MetPy's methods
Thermodynamics dry_lapse, moist_lapse, saturation_vapor_pressure, saturation_mixing_ratio, dewpoint_from_vapor_pressure

Style and colour
Settings rcParams, rc_context, rcdefaults, style.use with matplotlib's 31 style sheets
Colormaps every matplotlib colormap, ListedColormap, LinearSegmentedColormap.from_list
Norms Normalize, LogNorm, BoundaryNorm, TwoSlopeNorm, CenteredNorm, SymLogNorm, NoNorm
Interop matplotlib colormaps, norms, tickers and date locators are accepted as they are
