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);
hold on
axis([1 2 -1 1])
for i=1:numel(t)


Animated Plot Using drawnow in Matlab

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.
