MATLAB: Copy an independant figure to panel in app designer

Antenna Toolboxapp designergraphicspattern

Hi guys,

i have a problem and i don't know how to solve this. I want to copy a graphics of an independant figure to a panel created in app designer.

I've tried with copyobj and it seemed to work but it won't show the dBi of an antenna's 3dpattern.

this is a part of my code:

antennaObject = design(dipole,app.FreqEditField.Value);

antennaObject.Length = app.Dipolelength;

antennaObject.Width = app.Dipolewidth;

plotFrequency = app.FreqEditField.Value;

pattern(antennaObject, plotFrequency)

ax = gca;

copyobj(ax,app.Panel)

delete(f1)

You can see it cannot save the dBi value from the left figure.

Thank you for your support.

You have to copy all desired objects from the figure listed in the figure's "children" property.

Here's a demo that copies all objects from 'fig' (blue, regular figure) to 'uifig' (yellow, uifigure).

You probably only want some of the objects which you can select from fig.Children.

uifig = uifigure('Color',[1 1 .8])
fig = figure('color',[.8 1 1]);
ax = axes(fig);
plot(ax, magic(3))
legend(ax)
colorbar(ax)
copyobj(fig.Children, uifig)

Use copyobj() to copy all of the children from your saved figure's axes to the UIAxes.

Here's a functional demo.

% Create a figure, save it, and close it. 
mainFig = figure(); 
plot(magic(4),'-o')
savefig('MainFigure.fig') % use full path whenever possible; see fullfile()

close(mainFig)

% 1) Create a UIFigure and UIAxes (For app designer, skip this step)
% 2) Open the main figure in an invisible state.
% 3) Get the axis handle of the figure.
% 4) Copy all children of the axis handle to the UIAxes.
% 5) Close the invisible main figure.
% 1) Create UIAxes; Skip this step if you're using app designer.
app.UIFigure = uifigure(); 
app.UIAxes = uiaxes(app.UIFigure); 
% 2) OPen the main figure, invisible.
figHandle = openfig('MainFigure.fig','invisible') % use full path whenever possible; see fullfile()
% 3) Get all axis handles that belong to the invisible figure
axesHandle = findobj(figHandle,'type','axes'); 
%4) Copy all children of the axis to your UIFigure.
% If there are more then 1 axes found on the invisible
% figure, this will only copy the first axes listed.
% Replace input #2 with your UIAxes handle
copyobj(axesHandle(1).Children, app.UIAxes);
% Close the invisible figure
close(figHandle)

To delete the demo figure from you system,

delete('MainFigure.fig')

You can use copyobj() to copy the content on the external axis on to your UIAxis. This will not copy axis labels, titile, or legends but those items can be copied separately.

Step 1 is to open your external figure and get the axis handle. I'm assuming there is only 1 axis on the figure, otherwise this will need to be adapted to get the handle of the specific axis being copied.

fig = openfig('storage/psychplot_base.fig', 'invisible');
ax = findobj(fig,'Type','Axes');  % assuming 1 and only 1 handle is returned

Step 2 is to copy the children of the external axes to the app's UIAxes.

% Assuming app.UIAxes is the handle to your axes, 
copyobj(ax.Children, app.UIAxes)

Step 3 is to delete the external figure

delete(fig)
