16. How to remove the top border of UIAxes

When using UIAxes, even if XLabel, YLabel, and Title are deleted, there is still space reserved for Title above UIAxes:
Insert picture description here
For this we can adjust the reserved space of Title to a minimum to solve this problem. Specifically, you can adjust the following two properties:

It is recommended to modify the following TitleFontSizeMulitiplier property, which is the title scaling factor, so that only the Title is adjusted. Adjusting one of these two arbitrarily as shown in the figure below can eliminate the Title reserved space:

17. How to generate an attribute returner when the button is pressed

Insert picture description here

You only need to generate a new UIFigure and various controls through code in the callback function: Insert picture description here
and call the local callback function when the button on the new UIFigure is pressed, change the global variables, and delete the new UIFigure:

This part of the code:

			typeSetFig=uifigure(); 
            typeSetFig.Name='settype';
            typeSetFig.Color=[0.949 0.949 0.949];
            typeSetFig.Position=[app.getcolorUIFigure.Position(1),...
                                app.getcolorUIFigure.Position(2)+app.getcolorUIFigure.Position(4)-220,...
                                180 190];
            btgroup=uibuttongroup(typeSetFig);
            btgroup.Position=[10 50 160 130];
            btgroup.Title=[];
            
            Button1=uiradiobutton(btgroup);
            Button1.Text='RGB (0-1)';

18. How to judge the selection of radio buttons

First, set the same callback function for the buttons of the radio button group, find the currently selected button through the SelectedObject of the button group and get its Text property:

then compare the text of the selected button with the text of each button:
