uistack on legend and axes objects

I have several legends which I would like to be stacked on top of the AXES objects in a figure window. I used to be able to use UISTACK to achieve this, but after upgrading to R2015b it no longer works.

Here is an example:

% make some data for plotting
x=randn(100,1);
y=2*x + randn(100,1);
z=x.^2 + randn(100,1);

% generate plots and legends
hFig=figure;
subplot(2,1,1)
plot(x,y,'bx','DisplayName','Linear')
hL1=legend('show');
subplot(2,1,2)
plot(x,z,'rx','DisplayName','Quadratic')
hL2=legend('show');

% move legends over the opposite plot to visualize stacking
hL1.Position=[0.79    0.32    0.2    0.2];
hL2.Position=[0.79    0.57    0.2    0.2];

% try to reorder stack to put legends on top
uistack([hL1 hL2],'top')

% display object stack order (legends have not been moved to top of stack)
disp(hFig.Children)

I want the stack to be: Legend, Legend, Axes, Axes However, after using UISTACK, the stack order is still: Legend, Axes, Legend, Axes

Is there a workaround to get the desired stack order?

Hi Cameron,

I made a few changes to the programme and I believe it is working now. Can you check this?

% make some data for plotting
x=randn(100,1);
y=2*x + randn(100,1);
z=x.^2 + randn(100,1);

% generate plots and legends
hFig=figure;
subplot(2,1,1)
plot(x,y,'bx','DisplayName','Linear')
hL1=legend('show');
subplot(2,1,2)
plot(x,z,'rx','DisplayName','Quadratic')
hL2=legend('show');

% move legends over the opposite plot to visualize stacking
% hL1.Position=[0.79    0.32    0.2    0.2];
% hL2.Position=[0.79    0.57    0.2    0.2];
set(hL1,'Position',[0.79    0.32    0.2    0.2]) %Struct field assignment overwrites a value with class "double", so not doing hL1.Position
set(hL2,'Position',[0.79    0.57    0.2    0.2])

% try to reorder stack to put legends on top
uistack([hL1 hL2],'top')

% display object stack order (legends have not been moved to top of stack)
disp(get(hFig,'Children'))

Cheers,

This does not solve the problem I am referring to in my question above. The code I have provide runs without errors in MATLAB 2014b or later.

I guess you are running an earlier MATLAB version. The error you refer to: "Struct field assignment overwrites a value with class "double"" will not occur in later versions of MATLAB.

I have only had problems with setting the legend stacking in 2015b. I had no problems in 2014a and earlier.
