# MATLAB Animated Plot

This tutorial will introduce how to draw an animated plot using the `drawnow`

command and `pause()`

function in MATLAB.

## Draw an Animated Plot Using the `drawnow`

Command and `pause()`

Function in MATLAB

If you want to make an animated plot and see the plot being made in real-time, you can use a loop and `drawnow`

command. The `drawnow`

command updates figures on each callback. To draw an animated plot, you have to use it inside a loop to plot one variable in one iteration and update the figure using the `drawnow`

command. For example, let’s draw the animated plot of a sine wave. See the code below.

```
t = 1:0.001:2;
x = sin(2*pi*t);
figure
hold on
axis([1 2 -1 1])
for i=1:numel(t)
plot(t(i),x(i),'.','Color','b')
drawnow
end
```

Output:

You can choose different options depending on your requirements. You can change the axis limits using the `axis`

function. You can change the plot color using the `Color`

property and plot marker. If you want to change the timing of the animation, you can use the `pause()`

function instead of the `drawnow`

command to give the animation your desired animation time. You can pass the time in seconds inside the `pause()`

function. So a best practice will be to use a value in milliseconds; otherwise, the animation will be very slow.
