# plot3

3-D line plot

## Syntax

plot3(X1,Y1,Z1,...)
plot3(X1,Y1,Z1,LineSpec,...)
plot3(...,'PropertyName',PropertyValue,...)
h = plot3(...)

## Description

The plot3 function displays a three-dimensional plot of a set of data points.

plot3(X1,Y1,Z1,...), where X1, Y1, Z1 are vectors or matrices, plots one or more lines in three-dimensional space through the points whose coordinates are the elements of X1, Y1, and Z1.

plot3(X1,Y1,Z1,LineSpec,...) creates and displays all lines defined by the Xn,Yn,Zn,LineSpec quads, where LineSpec is a line specification that determines line style, marker symbol, and color of the plotted lines.

plot3(...,'PropertyName',PropertyValue,...) sets properties to the specified property values for all line graphics objects created by plot3. See lineseries properties for a description of the properties you can set.

h = plot3(...) returns a column vector of handles to lineseries graphics objects, with one handle per object.

## Examples

Plot a three-dimensional helix.

```t = 0:pi/50:10*pi;
plot3(sin(t),cos(t),t)
xlabel('sin(t)')
ylabel('cos(t)')
zlabel('t')
grid on
axis square```

expand all

### Tips

If one or more of X1, Y1, Z1 is a vector, the vectors are plotted versus the rows or columns of the matrix, depending whether the vectors' lengths equal the number of rows or the number of columns.

You can mix Xn,Yn,Zn triples with Xn,Yn,Zn,LineSpec quads, for example,

```plot3(X1,Y1,Z1,X2,Y2,Z2,LineSpec,X3,Y3,Z3)
```

See LineSpec and plot for information on line types and markers.
