plot

Linear 2-D plot.

📝 Syntax

• plot(Y)

• plot(X1, Y1, ...)

• plot(X1, Y1, LineSpec, ...)

• plot(..., propertyName, propertyValue, ...)

• plot(ax, ...)

• go = plot(...)

📥 Input argument

• X1 - x-coordinates: vector or matrix.

• Y1 - y-coordinates: vector or matrix.

• LineSpec - Line style, marker, and/or color: character vector or scalar string.

• ax - a scalar graphics object value: parent container, specified as a axes.

• propertyName - a scalar string or row vector character. see help of 'line' for property list.

• propertyValue - a value.

📤 Output argument

• go - a graphics object: line type.

📄 Description

plot(Y) plots the columns of Y versus their index.

plot(X, Y) plots line defined by X versus Y pair.

go = plot(...) returns a column vector of line graphics objects.

LineSpec is a string used to change the characteristics of the line and is composed of three optional parts in any order:

The SymbolSpec specifies the symbol to be drawn at each data point:

Symbol	Description
'o'	Circle symbol
'x'	Times symbol
'+'	Plus symbol
'*'	Asterisk symbol
'.'	Dot symbol
's'	Square symbol
'd'	Diamond symbol
'v'	Downward-pointing triangle symbol
'^'	Upward-pointing triangle symbol
'>'	Left-pointing triangle symbol
'<'	Right-pointing triangle symbol

The LineStyleSpec specifies the line style to use for each data series:

Style	Description
'-'	Solid line style
'--'	Dashed line style
'-.'	Dot-Dash-Dot-Dash line style
':'	Dotted line style

The ColorSpec specifies the line color to use for each data series:

Color	Description
'k'	Color Black
'y'	Color Yellow
'm'	Color Magenta
'c'	Color Cyan
'r'	Color Red
'b'	Color Blue
'g'	Color Green

💡 Examples

Default abscissae using indices:

f = figure()
plot(sin(0:0.1:2*pi))

Using explicit abscissae:

f = figure()
x = [0:0.1:2*pi]';
plot(x, sin(x))

Multiple curves with shared abscissae:

f = figure()
x = [0:0.1:2*pi]';
plot(x, [cos(x), cos(2*x), cos(3*x)])

Color and Size of Markers:

f = figure();
x = -pi:pi/10:pi;
y = tan(sin(x)) - sin(tan(x));
plot(x ,y, '--rs','LineWidth', 2, 'MarkerEdgeColor','k', 'MarkerFaceColor','g', 'MarkerSize', 11)

Adding Title and Axis Labels:

f = figure();
x = linspace(0, 10, 150);
y = sin(5*x);
plot(x,y,'Color',[0,0.7,0.9])
title(_('2-D Line Plot'))
xlabel('x')
ylabel('sin(5x)')
