## Plot a semivariogram object

### Description

Utilities for plotting pilot semivariograms or fitted models.

`plot.fitsvar` plots a fitted variogram model.

`plot.svar.bin` plots the binned semivariances.

`plot.np.svar` plots a local polynomial estimate of the semivariogram.

### Usage

``````## S3 method for class 'fitsvar'
plot(
x,
y = NULL,
legend = TRUE,
xlab = "distance",
ylab = "semivariance",
xlim = NULL,
ylim = c(0, 1.25 * max(x\$fit\$sv, na.rm = TRUE)),
lwd = c(1, 2),
...
)

## S3 method for class 'svar.bin'
plot(
x,
y = NULL,
xlab = "distance",
ylab = "semivariance",
xlim = NULL,
ylim = c(0, max(x\$biny, na.rm = TRUE)),
...
)

## S3 method for class 'np.svar'
plot(
x,
y = NULL,
xlab = "distance",
ylab = "semivariance",
xlim = NULL,
ylim = c(0, max(x\$biny, na.rm = TRUE)),
...
)
``````

### Arguments

 `x` a variogram object. Typically an output of functions `np.svariso` or `fitsvar.sb.iso`. `y` ignored argument. `legend` logical; if `TRUE` (default), a legend is added to the plot. `xlab` label for the x axis (defaults to "distance"). `ylab` label for the y axis (defaults to "semivariance"). `xlim` x-limits. `ylim` y-limits. `lwd` line widths for points (estimates) and lines (fitted model) respectively. `add` logical; if `TRUE` the semivariogram plot is just added to the existing plot. `...` additional graphical parameters (see `par`).

### Value

No return value, called for side effects (generate the plot).

`svariso`, `np.svariso`, `fitsvar.sb.iso`.
