I'm trying to display a pdeplot graph in appdesigner, but I have no idea how to get it do display using app.UIAxes. Right now my pdeplot code is:
pdeplot(model2,'XYData',sol2(:,3600))
Could anyone help me with this?

Hi Andrew
As of R2020b, pdeplot does not support taking axes objects as input parameter which is the case with other plot functions. I have brought this issue to the concerned people and it might be considered in any future release.
Hope this helps

A possible option is using pdeviz
Use "pdeviz(figure,___)" syntax to specify plot area in the app designer. The code should be something like this:
% you need to have yourmeshdata
v = pdeviz(app.RightPanel, yourmeshdata); %specify where to plot the data
v.NodalData = sol2(:,3600);

@Megumi Fukuda Thanks but how can I use pdeviz with a mesh that is generated elsewhere?
With pdemesh, this is straightforward:
nodes = app.UITable2.Data;
elements = app.UITable.Data;
pdemesh(nodes',elements');
pdeviz on the other hand doesn't seem to allow you to do this....
pde.FEMesh.Nodes = app.UITable2.Data';
pde.FEMesh.Elements = app.UITable.Data';
pdeviz(pde.FEMesh);
I keep getting "Unable to find a mesh".

I find a solution,we can copy the date of pdegplot() to app.UIAxes:
pdegplot(model);%偏微分方程求解
hFig = gcf; % 获取当前图形窗口的句柄
hAx = gca; % 获取当前坐标系的句柄
% 复制绘图对象到 app.UIAxes
copyobj(allchild(hAx), app.UIAxes);
% ylim(app.UIAxes, [-80, 0]);
% xlim(app.UIAxes, [-80, 250]);
% zlim(app.UIAxes, [-80, 80]);
view(app.UIAxes,15,25);
% 关闭图形窗口
close(hFig);

This worked great to clear this error I was getting:
"Error using uicontextmenu
Parent must be a Figure
Error in pdeplot (line 1186)
hc=colorbar(ax,'UIContextMenu',uicontextmenu(ax.Parent)); % Disable context menu "
when trying to plot in the app designer using:
pdeplot(app.UIAxes3,Model_TD_S,"XYData",Solution_CD_S.VonMisesStress)
