![]() (I get commissions for purchases made through links in this post. This is a comprehensive post, so let’s crack on. I’ll begin with the basics to confirm what I mean by contour drawing, then list the different types of contour drawings, and end with related questions. The artist draws or traces the outline of the object and fills in the interior shapes of the object by progressively adding detail, shading, and/or color. ![]() Yet there are different types of contour drawing, so what do they mean?Ī contour drawing is a technique that is used to study the shape and volume of an object and calculate the correct proportions. The polygon edges.A contour drawing is, at its core, about using the fewest lines possible for the maximum effect. Hatching is supported in the PostScript, PDF, SVG and AggĬontourf differs from the MATLAB version in that it does not draw If None, no hatching will be added to the contour. hatches : List, optionalĪ list of cross hatch patterns to use on the filled areas. Iterable is shorter than the number of contour levels Specifying a set of linestyles to be used. Linestyles can also be an iterable of the above strings Linestyle from rcParams = 'dashed' setting. In that case, negative contours will take their If linestyles is None, the default is 'solid' unless the linesĪre monochrome. The Normalize instance, overriding the default color scalingīased on levels. If not None, either or both of these values will be supplied to If not given, the default linear scaling is used. Values to the canonical colormap range for mapping toĬolors. If a colormap is used, the Normalize instance scales the level If both colors and cmap are given, an error is raised. The colormapĭefaults to rcParams = 'viridis'. cmap : str or Colormap, optionalĪ Colormap instance or registered colormap name. The alpha blending value, between 0 (transparent) and 1 (opaque). This shortcut does only work forĬolor strings, not for other ways of specifying colors.īy default (value None), the colormap specified by cmap 'red' instead of to colorĪll levels with the same color. Sequence is shorter than the number of levels, it's repeated.Īs a shortcut, single color strings may be used in place of The sequence is cycled for the levels in ascending order. colors : color string or sequence of colors, optional Nearest those points are always masked out, other triangularĬorners comprising three unmasked points are contoured as usual.ĭefaults to rcParams = True, which defaults to True. If True, only the triangular corners of quads If False, any quad touching a masked point is If array-like, draw contour lines at the specified levels.Įnable/disable corner masking, which only has an effect if Z isĪ masked array. The level heights are automatically chosen. levels : int or array-like, optionalĭetermines the number and positions of the contour lines / regions. The height values over which the contour is drawn. If not given, they are assumed to be integer indices, i.e. That len(X) = M is the number of columns in Z and ![]() X and Y must both be 2-D with the same shape as Z (e.g.Ĭreated via shgrid), or they must both be 1-D such Except as noted, function signatures and return valuesĪre the same for both versions.
