plot

Plot eye diagram, eye contour, or eye mask object

Since R2024a

Syntax

plot(obj)

plot(obj,type)

plot(obj, Name=Value)

Description

plot(obj) plots the eye diagram, eye contour, or eye mask object obj.

plot(obj,type) plots the specified type of plot from eye diagram object obj.

plot(obj, Name=Value) plots eye diagram, eye contour, or eye mask object obj using one or more name-value pair arguments in addition to the input argument in the previous syntax. Unspecified arguments take default values.

Input Arguments

obj — Eye diagram, eye contour, or eye mask object

eyeDiagramSI object | eyeContour object | eyeMask object

Eye diagram, eye contour, or eye mask object to plot.

type — Type of plot to show

EyePattern (default) | SymbolPDFs | ClockPDF

Type of plot to show:

• EyePattern — Plots a 2D color histogram of the eye pattern.

• SymbolPDFs — Plots the set of one 2D color histogram for each symbol level.

• ClockPDF — Plots the line plot of the clock PDF histogram.

Note

You can only define this argument when obj is an eye diagram object.

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: plot(obj,Background='eyeDSI') plots an eye mask object which uses the eyDSI eyeDiagramSI object as a background for the mask.

TimeUnit — Unit for time axis

Seconds (default) | Samples | UI

Unit for time axis, specified in Seconds, Samples, or UI.

Note

You can only define this argument when obj is an eye diagram or eye contour object.

Data Types: char

AlphaData — Transparency of 2D color histogram

1 (default) | scalar in the range [0, 1]

Transparency of the 2D color histogram, specified as a scalar between 0 (transparent) and 1 (opaque).

Note

You can only define this argument when obj is an eye diagram object.

Data Types: double

Position — Position at which to display eye mask

vector

Position at which to display the mask, relative to the threshold and timing origin for a given eye. If you do not provide this information, the function uses the Position property from the eye mask object.

Data Types: char

Note

If obj is an eye mask object, you can use Polygon properties as Name-Value pair arguments. For a complete list, see Polygon Properties.
