Signor, eds., Analytical Paleobiology, Paleontological Society Short Courses in Paleontology No. For source code on which this program is based and a justification of the approach used in calculating these error bars, see Raup, D.M., 1991, The future of analytical paleobiology. This program is based on David Raup’s program for calculating the error bars on percentage or ratio data that he presented in the 1991 Analytic Paleobiology short course. Be sure to read the instructions for Analytic Rarefaction. If you have any comments or questions, please contact Steven Holland at RarefactionĪnalytic Rarefaction uses the solution presented by Raup (1975) and Tipper (1977) and runs very quickly, even on large data sets. Most of these (except for Analytic Rarefaction) are available only for macOS. All I ask is that if you use these for research that results in a presentation or published paper, acknowledge me. Returns the Axes object with the plot drawn onto it.I have written several programs that are available free of charge. Other keyword arguments are passed through to ax matplotlib Axes, optionalĪxes object to draw the plot onto, otherwise uses the current Axes. When hue nesting is used, whether elements should be shifted along theĬategorical axis. Often look better with slightly desaturated colors, but set this toġ if you want the plot colors to perfectly match the input colorĬolor for the lines that represent the confidence interval.

To resolve ambiguity when both x and y are numeric or when Inferred based on the type of the input variables, but it can be used Orientation of the plot (vertical or horizontal). Seed or random number generator for reproducible bootstrapping. Multilevel bootstrap and account for repeated measures design. Identifier of sampling units, which will be used to perform a units name of variable in data or vector data, optional Number of bootstrap iterations to use when computing confidence If None, no bootstrapping will be performed, andĮrror bars will not be drawn. “sd”, skip bootstrapping and draw the standard deviation of the Size of confidence intervals to draw around estimated values. Statistical function to estimate within each categorical bin. estimator callable that maps vector -> scalar, optional Order to plot the categorical levels in, otherwise the levels are order, hue_order lists of strings, optional Otherwise it is expected to be long-form. data DataFrame, array, or list of arrays, optionalĭataset for plotting. Parameters x, y, hue names of variables in data or vector data, optional When the data has a numeric or date type. This function always treats one of the variables as categorical andĭraws data at ordinal positions (0, 1, … n) on the relevant axis, even Grouping variables to control the order of plot elements. Additionally, you can use Categorical types for the Objects are preferable because the associated names will be used toĪnnotate the axes. In most cases, it is possible to use numpy or Python objects, but pandas Variables will determine how the data are plotted.Ī “wide-form” DataFrame, such that each numeric column will be plotted. Objects passed directly to the x, y, and/or hue parameters.Ī “long-form” DataFrame, in which case the x, y, and hue Vectors of data represented as lists, numpy arrays, or pandas Series Input data can be passed in a variety of formats, including: In that case, other approaches such as a box or violin plot may be more Show the distribution of values at each level of the categorical variables.
