How to create a plot with constant figure size and inner position

Hi,

Is it possible to generate a plot, where one is in control of the figure size, and the location of the inner position of the plot and of the figure? Ideally I'd like to control the TightInset parameter, but since that is "read-only", it doesn't seem like an option.

I'm trying to create a plot for a data-sheet, where the sizes of the figure as well of the axes and its position are always the same. Everything should always be in the same postion independently of being active on the plot or not. Generally I'd like the plot to always have the same size and location independant of if I'm using two y-axis, with or without labels, titles, font sizes, etc.

I've dabbled with the different parameters from

https://se.mathworks.com/help/matlab/ref/matlab.graphics.axis.axes-properties.html

and

https://se.mathworks.com/help/matlab/ref/matlab.ui.figure-properties.html

but there doesn't seem to be an obvious way of doing this.

Issue I encountered was:

set innerposition values of ax, ax1,ax2, to same value ... (to align y-axis of UI figures) on a figure.

set PositionConstraint='innerposition' on ax,ax1, and ax2

figure looks good , all aligned

savefig the fig

openfig the fig --- ax1 innerposition got changed

and ax,ax1,ax2 Position.constraint changed to outerposition.

Any idea how to keep innerposition alignment?

Hi

You can create plots with a fixed position and a fixed size by setting the 'position' property. By default, 'position' is in pixels.

x0=50;
y0=50;
width=500;
height=400;
set(gcf,'position',[x0,y0,width,height])

You can specify other units (inches, centimeters, normalized, points, or characters). For example:

set(gcf,'units','points','position',[x0,y0,width,height])

Thanks for your reply.

Your suggestion alone doens't fix the problem, as the inner parts of the figure change positions when labels, axes, etc are added / removed.

The code below does exactly what I need. Thus combining the inner position parameter of the axes handle with the outer figure size solves the problem. And remember to convert from pixels to points, if you are using pixles, as the figure only supports points.

F=figure('PaperPositionMode','manual');
AX = gca;
F.Resize = 'off';
F.Units = 'points';
F.PaperUnits = 'points';
AX.Units = 'points';
AX.Clipping = 'on';
AX.PositionConstraint = 'innerposition';
AX.InnerPosition = [0 0 FigWidth-BufferWidth FigHeight-Height]*72/96; % converting from pixels to points
F.OuterPosition = [0 0 FigWidth FigHeight]*72/96; % converting from pixels to points
F.PaperPosition = [0 0 FigWidth FigHeight]*72/96;% converting from pixels to points

Thanks for your code, @Jesper Bjerregaard! It worked wonderfully for me. I was getting upset with the OuterPosition, Position, and InnerPosition of several figure and axes handles. In fact, I do not comprehend the difference between Position and InnerPosition. Does anyone know? The documentation does not make it clear.

No problem.

They seem to be the same.
