Hi, i created a function in matlab that plots a graph giving some inputs. i want to put this function in my GUI and show the graph in the GUI. How can i do that?

At this moment the function runs in the GUI, but the plot it's shown in a figure, not in the UIFigure, how can i fix this problem?

thank you!

You have to specify the axis handle as the parent of your plotting function. See example.

if I have this function for example, not defined in app designer:

function plotsomething(inp1,inp2,...)
%code for the function
figure(1)
g=fill3(l2.XYZ(:,:,1)',l2.XYZ(:,:,2)',l2.XYZ(:,:,3)','w');
set(g,'LineWidth',2);
view([0,90]);
axis equal,hold on
xlabel(' x-coordinate')
ylabel(' y-coordinate')
zlabel(' z-coordinate')
title(' partition layout')
grid on
h=line([ref.mac_pos(1) ref.mac_pos(1)+ref.C_mac],[ref.mac_pos(2) ref.mac_pos(2)],[ref.mac_pos(3) ref.mac_pos(3)]);

if i want to display this in app designer, so I update the code of the function:

function plotsomething(inp1,inp2,...)
% figure(1) I suppress the figure
fill3(app.UIAxes,l2.XYZ(:,:,1)',l2.XYZ(:,:,2)',l2.XYZ(:,:,3)','w');
set(app.UIAxes,'LineWidth',2);
view(app.UIAxes,[0,90]);
axis equal,hold on
xlabel(app.UIAxes,'x-coordinate')
ylabel(app.UIAxes,'y-coordinate')
zlabel(app.UIAxes,'z-coordinate')
title(app.UIAxes,'partition layout')
grid on
h=line(app.UIAxes,[ref.mac_pos(1) ref.mac_pos(1)+ref.C_mac],[ref.mac_pos(2) ref.mac_pos(2)],[ref.mac_pos(3) ref.mac_pos(3)]);

is this what you mean? thank you!

I see that this is a plotting function.

It is good practice to include a parent handle in the inputs of plotting functions so that all internal plotting commands can act on the specified axes/figure/etc.

For example,

function plotsomething(inp1,inp2,axisHandle)
    fill3(axisHandle, . . .)
    set(axisHandle, . . .);
    view(axisHandle, . . .);
    axis(axisHandle, 'equal'); 
    hold(axisHandle, on)
    xlabel(axisHandle,'x-coordinate')
    % etc....
end
