update UIAxes when change values in a table in app Designer

hi,

i have a UITable, UIAxes and a button. My program plots a wing giving some data from the table. I want to update the plot when i change the values in the table and press the button. I tried to set the UIAxes property: next plot---->replace children and replace all, but it doesn't work, the program add the new plot to the older. How can i delete the older plot? This is a piece of the code

function ButtonPushed(app, event)
%take data from the table
app.geo.c=str2double(app.UITable_wing.Data(1,6));					
app.geo.dihed=str2double(app.UITable_wing.Data(1,9))*(pi/180);				
app.geo.b=str2double(app.UITable_wing.Data(1,11));
app.g = ....
app.ref =....
%plot
geometryplot1(app.g,app.geo,app.ref,app.UIAxes)
end

how can i fix the problem?

Thank you!

Marco - does the function geometryplot1 create the plot for you? How is it doing that? You may need to show us the code for this function so that we can get an idea of how the plot is created and whether hold on is being used to maintain/hold all previous plots to the axes.

[Marco Picillo]

this is the code of the function

function[]=geometryplot1(lattice,geo,ref,axHandle);
[t q2 q3]=size(lattice.VORTEX);

%Changing variables to plot only partition outline
% g2=geo;
% g2.nx=double(g2.nx>0);
% g2.ny=double(g2.ny>0);

% g2.fnx=double(g2.fnx>0);
% s2.AS=1;
% s2.alpha=0;
% s2.betha=0;
% s2.P=0;
% s2.Q=0;
% s2.R=0;
% s2.ALT=0;
% s2.rho=1;
% s2.pgcorr=0;

[l2,ref]=fLattice_setup2(g2,s2,1);

fill3(axHandle,l2.XYZ(:,:,1)',l2.XYZ(:,:,2)',l2.XYZ(:,:,3)','w','LineWidth',2);
view(axHandle,[0,90]);
axis(axHandle,'equal'),hold(axHandle,'on')
xlabel(axHandle,'Aircraft body x-coordinate')
ylabel(axHandle,'Aircraft body y-coordinate')
zlabel(axHandle,'Aircraft body z-coordinate')
title(axHandle,'3D wing and partition layout')
grid(axHandle,'on')

line(axHandle,[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)],'lineWidth',5);
plot3(axHandle,geo.ref_point(1),geo.ref_point(2),geo.ref_point(3),'r+','MarkerSize',15,'linewidth',3);
plot3(axHandle,geo.ref_point(1),geo.ref_point(2),geo.ref_point(3),'ro','MarkerSize',15,'linewidth',3);
plot3(axHandle,geo.CG(1),geo.CG(2),geo.CG(3),'ko','MarkerSize',15,'linewidth',3);
plot3(axHandle,geo.CG(1),geo.CG(2),geo.CG(3),'kx','MarkerSize',15,'linewidth',3);


end

in appDesigner i call this function in button pushed callback

[J. Alex Lee]

can you just call "cla(axHandle)" inside your geometryplot1 function?

My choice would be to have a plot initializer if the "things" you plot is always the same, and in your plot updater just update the data associated with each plot handle.

Maybe an even better way with more modern matlab would be to use the custom charts mechanism

thank you! Now it works properly
