# 52_cmv_plotting_functions: Plots of Continuous Multivariate Models In probhat: Multivariate Generalized Kernel Smoothing and Related Statistical Methods

## Description

Plots of bivariate and trivariate continuous probability distributions.

## Usage

 ``` 1 2 3 4 5 6 7 8 9 10 11``` ```#calls barsurf::plot_cfield or barsurf::plot_surface plot_cpd_bv (sf, in3d=FALSE, data, ..., n=30, main, xlab, ylab, zlab, xlim, ylim, zlim, add=FALSE, point.color) #calls barsurf::plot_cfield_3d plot_cpd_tv (sf, iso=FALSE, ..., main, xlab, ylab, zlab, xlim, ylim, zlim, z.reverse=FALSE) ```

## Arguments

 `sf` A suitable function object. Here, this is a continuous multivariate probability distribution, with two or three random variables. Refer to the references and see also sections. `in3d` Logical, if true, produce a 3D plot. `iso` Logical, if true, produce an isosurface plot. `data` Logical, if true, plot data points. Ignored, if in3d or add is true, or sf is a conditional distribution. Defaults to true, if the number of observations is not more than 2000. `main, xlab, ylab, zlab` Optional strings, main/axes titles. Note that these depend on the barsurf package. `xlim, ylim, zlim` Optional length-2 numeric vectors, giving the plot ranges. `z.reverse` Logical, if true, reverse the z axis. Ignored, if zlim supplied. `n` Numeric vector of length one or two, giving the number of grid points in each direction. `add` Logical, if true, add to a previous plot. Ignored, in 3d case. `point.color` String, the (data) point color. `...` Other arguments for barsurf functions, refer to details.

## Details

These functions call barsurf::plot_cfield, barsurf::plot_surface, barsurf::plotf_cfield_3d and barsurf::plotf_isosurface.

There are some private intermediate functions, that change some of the defaults.
Note that by default, more detail is used in bivariate CDFs than bivariate PDFs.
