Syntax

plot(y)

plot(x, y)

plot(x, y, attributes)

plot(x1, y1, x2, y2, ..., xN, yN)

plot(x1, y1, x2, y2, ..., xN, yN, attributes)

plot(y, name1, value1, ..., nameN, valueN)

plot(x, y, name1, value1, ..., nameN, valueN)

plot(x1, y1, attributes1, x2, y2, attributes2, ..., xN, yN, attributesN)

obj = plot(y)

obj = plot(x, y)

obj = plot(x, y, attributes)

obj = plot(x1, y1, x2, y2, ..., xN, yN)

obj = plot(x1, y1, x2, y2, ..., xN, yN, attributes)

obj = plot(y, name1, value1, ..., nameN, valueN)

obj = plot(x, y, name1, value1, ..., nameN, valueN)

obj = plot(x1, y1, attributes1, x2, y2, attributes2, ..., xN, yN, attributesN)

Description

Generates a plot. plot(y) plots the columns of y against the indexes of the columns. If y is complex, plot(y) plots imag(y) against real(y). If x and y are real vectors, plot(x, y) plots y against x. If x or y is complex, plot(x, y) plots real(y) against real(x). plot(x, y, attributes) plots y against x using the specified attributes. plot(x1, y1, x2, y2, ..., xN, yN, attributes) plots y1, y2, ..., and yN against x1, x2, ..., and xN, respectively. In this syntax, LabVIEW uses the specified attributes for the last plot and the default attributes for previous plots. plot(x, y, name1, value1, ..., nameN, valueN) sets the line attributes according to the attribute names and values you specify.

Examples

Inputs

Name Description
x Specifies a vector or matrix you want to plot.
y Specifies a vector or matrix you want to plot.
attributes Specifies valid plot attributes. Order the plot attributes by color, point style, and line style. For example, 'bo-' specifies that the plot is blue, marks points with circles, and uses solid lines. You also can use the line attributes to set the color, point style, line style, and other attributes of the plot. attributes is a string that accepts a combination of the following values.

'b' Colors the plot blue.
'c' Colors the plot cyan.
'g' Colors the plot green.
'k' Colors the plot black.
'm' Colors the plot magenta.
'r' Colors the plot red.
'w' Colors the plot white.
'y' Colors the plot yellow.
'.' Marks points with dots.
'o' Marks points with circles.
'x' Marks points with crosses.
'+' Marks points with plus signs.
'*' Marks points with asterisks.
'-' Uses solid lines.
':' Uses dotted lines.
'-.' Uses dashed and dotted lines.
'--' Uses dashed lines.
name Specifies the name of the attribute. name is a string.
value Specifies the value of the attribute.

Outputs

Name Description
obj Returns the reference to the line object. obj is a reference to a line object.

Details

If you want to specify a complex input, use the following syntax: plot(z, attributes), where z = x + yi

To use the plot(x, y, attributes) syntax, you must specify real inputs. If you do not specify real inputs, LabVIEW replaces complex numbers with their real parts.

The following table lists the support characteristics of this function.

Supported in the LabVIEW Run-Time Engine No (returns error or is ignored)
Supported on RT targets No

Examples

X = [0:0.01:1];
Y = X.*X;
plot(X, Y, 'bo-')

X = sin(0:0.1:100);
plot(X, 'Color', 'g')
Y = axes;
set (Y, 'YLim', [-5, 5], 'XLim', [0, 600])
