Plotting Graphical Marks

Description

These functions provide plotting methods for various graphical marks. They are not intended to be called directly.

Usage

## S3 method for class 'vizi_points'
plot(x, plot = NULL, ...,
    n = Inf, downsampler = "lttb", jitter = "",
    sort = is.finite(n))

## S3 method for class 'vizi_lines'
plot(x, plot = NULL, ...,
    n = Inf, downsampler = "lttb", jitter = "",
    sort = is.finite(n))

## S3 method for class 'vizi_peaks'
plot(x, plot = NULL, ...,
    n = Inf, downsampler = "lttb", jitter = "",
    sort = is.finite(n))

## S3 method for class 'vizi_text'
plot(x, plot = NULL, ...,
    adj = NULL, pos = NULL, offset = 0.5)

## S3 method for class 'vizi_rules'
plot(x, plot = NULL, ...)

## S3 method for class 'vizi_bars'
plot(x, plot = NULL, ...,
    width = 1, stack = FALSE)

## S3 method for class 'vizi_intervals'
plot(x, plot = NULL, ...,
    length = 0.25, angle = 90)

## S3 method for class 'vizi_boxplot'
plot(x, plot = NULL, ...,
    range = 1.5, notch = FALSE, width = 0.8)

## S3 method for class 'vizi_image'
plot(x, plot = NULL, ...,
    alpha = NA, interpolate = TRUE, maxColorValue = 1)

## S3 method for class 'vizi_pixels'
plot(x, plot = NULL, ...,
    enhance = FALSE, smooth = FALSE, scale = FALSE,
    useRaster = TRUE)

## S3 method for class 'vizi_voxels'
plot(x, plot = NULL, ...,
    xslice = NULL, yslice = NULL, zslice = NULL)

Arguments

x	A graphical mark.
plot	A vizi_plot object.
...	Additional graphical parameters passed to the underlying base graphics plotting function.
n	Transformation. Maximum number of points to plot. This is useful for downsampling series with far more data points than are useful to plot. See downsample for details.
downsampler	Transformation. If n is less than the number of points, then this is the downsampling method to use. See downsample for details.
jitter	Transformation. Should jitter be applied to one or more position channels? One of "", "x", "y", or "xy".
sort	Transformation. Should the data be sorted (along the x-axis) before plotting? Mostly useful for line charts.
width	The width of the bars or boxplots.
stack	Should bars be stacked versus grouped side-by-side?
adj, pos, offset	See text.
length, angle	See arrows.
range, notch	See boxplot.
alpha	Opacity level from 0 to 1.
interpolate	See rasterImage.
maxColorValue	See col2rgb.
enhance	Transformation. The name of a contrast enhancement method, such as "hist" or "adapt" for enhance_hist() and enhance_adapt(), etc. See enhance for details.
smooth	Transformation. The name of a smoothing method, such as "gauss" or "bi" for filt2_gauss() and filt2_bi(), etc. See filt2 for details.
scale	Transformation. If TRUE, then all image values will be scaled to the range [0, 100]. This is useful for comparing images with differing intensity levels across facets or layers.
useRaster	Should a bitmap raster be used for plotting? This is typically faster on supported devices. A fallback to polygon-based plotting is used if raster plotting is not supported.
xslice, yslice, zslice	Numeric vectors giving the x, y, and/or z coordinates of the volumetric slices to plot. If none are provided, defaults to plotting all z-slices.

Details

These methods are not intended to be called directly. They are presented here to document the transformations and parameters they accept. These should be passed a list to the trans and params arguments in add_mark.

See add_mark for supported encodings.
