Setting desired margins and ratio for plot

Hi,

I would like to

1) set margins for my plot, which is authomatically shown as follows:

I need white upper margins in order to see the horizontal line connecting the diamonds above.

I have tried with Control axes layout (https://it.mathworks.com/help/matlab/creating_plots/automatic-axes-resize.html ) , with no result

2) I would also like the picture to be shown in normal ratios (I mean, same length for data units along x and y axis).

I have tried with data aspect ratio (https://it.mathworks.com/help/matlab/ref/daspect.html) in order to disable stretch-to-fill behavior by setting

daspect('manual') or daspect([1 1 1]) without succeeding...

I'd really appreciate the help.

thanks in advance!

"axis equal" will set the aspect ratio equal between both axes.

"xlim" and "ylim" will set the axis limits which you can use to add margins.

axis equal       % to set equal aspect ratio
ylim([-5,40])    % to add space above and below your data
xlim([-10,110])  % to add space to the left and right of your data

If you have the handle to you axis, it's best to specify the handle,

axh = gca(); % Get handle to axis
axis(axh,'equal')
ylim(axh,[-5,40])    
xlim(axh,[-10,110])

great, I needed to handle the axis,

thanks!

I recommend always using handles when possible.

Glad I could help!
