findobj not working with UIAxis
显示 更早的评论
I have an app with tabs and Axis as Children.
When using
axesInTab = findobj(currentTab, 'Type', 'matlab.ui.control.UIAxes');
i get 0x0 GraphicsPlaceholder but when using
% Direktes Zugreifen auf Children-Eigenschaft
children = currentTab.Children;
% Filtern der Children, um nur UIAxes zu erhalten
axesInTab = children(arrayfun(@(c) isa(c, 'matlab.ui.control.UIAxes'), children));
I can find the Axis as expected.
Anybody has an idear? (Btw second Function is from ChatGBT lol)

The 'Type' and the class of something are two different things.
The value of the uiaxes 'Type' property is 'axes', so
axesInTab = findobj(currentTab, 'Type', 'axes');
will work.
The uiaxes is of class 'matlab.ui.control.UIAxes', so that's why isa(_,'matlab.ui.control.UIAxes') returns true for it.
