How To Change Plot Size In Matlab

Setting the Figure Size and Position

The default output figure size is 8 inches wide past six inches loftier, which maintains the aspect ratio (width to tiptop) of the MATLAB figure window. The figure's default position is centered both horizontally and vertically when printed to a paper size of 8.five-by-11 inches.

You can change the size and position of the figure:

Using the Graphical User Interface
Using MATLAB Commands

Using the Graphical User Interface

Select Page Setup from the figure window'due south File carte to open the Page Setup dialog box. Click the Size and Position tab to brand changes to the size and position of your effigy on the printed page.

Use the text edit boxes on the left to enter new dimensions for your effigy. Or use the graphical user interface at the right to drag the borders and location of the "sample" figure with your mouse.

Settings y'all can change in the Size and Position window are as follows:

Way. Cull whether you want the figure to be the same size equally it is displayed on your screen, or you desire to manually change its size using the options in the Size and Position window.

The next two panels are enabled only when you select the Use manual size and position mode.

Transmission size and position. Enter the measurements and units for the size and position of the figure.

Graphical User Interface. Use the "Sample" effigy at the right of the dialog box to move and resize your MATLAB figure interactively.

To ready the width and height interactively, use the mouse to drag the edges of the "Sample" figure to the desired size.

To fix the margins of the figure (offsets from the left and top edges of the newspaper), drag the entire "Sample" effigy to a new position with the mouse.

If you want the figure resized to fill the newspaper, click Fill page. Note that Fill up page may modify the aspect ratio of your image. To get the maximum figure size without altering the attribute ratio, select Fix aspect ratio.

Note Changes you make using Folio Setup affect the printed output merely. They do non alter the figure displayed on your screen.

Using MATLAB Commands

To print your figure with a specific size or position, make sure that the PaperPositionMode belongings is set up to manual (the default). And then fix the PaperPosition property to the desired size and position.

The PaperPosition property references a four-element row vector that specifies the position and dimensions of the printed output. The form of the vector is

```
[left bottom width height]          
```

where

left specifies the distance from the left edge of the paper to the left edge of the figure.
bottom specifies the altitude from the bottom of the newspaper to the lesser of the effigy.
width and height specify the figure's width and peak.

The MATLAB default values for PaperPosition are

[0.25 2.v eight.0 half-dozen.0]

This instance sets the figure size to a width of 4 inches and height of two inches, with the origin of the figure positioned two inches from the left edge of the newspaper and one inch from the lesser edge.

set(gcf, 'PaperPositionMode', 'manual'); gear up(gcf, 'PaperUnits', 'inches'); set(gcf, 'PaperPosition', [2 1 4 2]);

Annotation PaperPosition specifies a bottom margin, rather than a top margin equally Page Setup does. When you set the top margin using Page Setup, MATLAB uses this setting to calculate the bottom margin, and updates the PaperPosition property appropriately.
