How to create a new figure in MATLAB?

Usually when I plot in MATLAB, it always draws on the same figure. How do I make it draw in a new figure?

I know it is pretty elementary, but I'm not finding it using Google Search.

Answer by Federico A. Ramponi for How to create a new figure in MATLAB?

figure;  plot(something);  

or

figure(2);  plot(something);  ...  figure(3);  plot(something else);  ...  

etc.

The other thing to be careful about, is to use the clf (clear figure) command when you are starting a fresh plot. Otherwise you may be plotting on a pre-existing figure (not possible with the figure command by itself, but if you do figure(2) there may already be a figure #2), with more than one axis, or an axis that is placed kinda funny. Use clf to ensure that you're starting from scratch:

figure(N);  clf;  plot(something);  ...

While doing "figure(1), figure(2),..." will solve the problem in most cases, it will not solve them in all cases. Suppose you have a bunch of MATLAB figures on your desktop and how many you have open varies from time to time before you run your code. Using the answers provided, you will overwrite these figures, which you may not want. The easy workaround is to just use the command "figure" before you plot.

Example: you have five figures on your desktop from a previous script you ran and you use

figure(1);  plot(...)    figure(2);  plot(...)  

You just plotted over the figures on your desktop. However the code

figure;  plot(...)    figure;  plot(...)  

just created figures 6 and 7 with your desired plots and left your previous plots 1-5 alone.

As has already been said: figure will create a new figure for your next plots. While calling figure you can also configure it. Example:

figHandle = figure('Name', 'Name of Figure', 'OuterPosition',[1, 1, scrsz(3), scrsz(4)]);  

The example sets the name for the window and the outer size of it in relation to the used screen. Here figHandle is the handle to the resulting figure and can be used later to change appearance and content. Examples:

Dot notation:

figHandle.PaperOrientation = 'portrait';  figHandle.PaperUnits = 'centimeters';  

Old Style:

set(figHandle, 'PaperOrientation', 'portrait', 'PaperUnits', 'centimeters');  

Using the handle with dot notation or set, options for printing are configured here.

By keeping the handles for the figures with distinc names you can interact with multiple active figures. To set a existing figure as your active, call figure(figHandle). New plots will go there now.

As simple as this-

figure, plot(yourfigure);  

Answer by gariepy for How to create a new figure in MATLAB?

Another common option is when you do want multiple plots in a single window

f = figure;  hold on  plot(x1,y1)  plot(x2,y2)  ...  

plots multiple data sets on the same (new) figure.
