Hi all,

I want to instead line legend by table.

Following is example.

            app.Panel_3.AutoResizeChildren = 'off';
            app.ax4 = subplot(1,1,1,'Parent',app.Panel_3);
            t=-10:1:10;
            t_sin = sin(t);
            plot(app.ax4,t,t_sin, '-ro', 'DisplayName','sin(t)');
            hold(app.ax4,"on");
            plot(app.ax4,t,tan(t), '-bo', 'DisplayName','tan(t)');
            
            app.UITable.ColumnName     = {'Line', 'Name', 'Check'};
            
            %% Get all line of app.ax3
            ax4_allLines     = findobj(app.ax4, 'type', 'line');
            ax4_allLinesName = {};
            
            for id = 1:length(ax4_allLines)
                
                linecolor       = rgb2hex(ax4_allLines(id).Color);
                marker          = ax4_allLines(id).Marker;
                if strcmp(marker,'none')
                    marker=[];
                end
                
                linestyle       =  ax4_allLines(id).LineStyle;
                
                ax4_allLinesName{end+1, 1}  = ['<hr style="height:2px;border-width:0;color: ' linecolor '">'];
                ax4_allLinesName{end, 2}    = ax4_allLines(id).DisplayName;
                ax4_allLinesName{end, 3}    = true;
            end
            app.UITable.Data = ax4_allLinesName;
%             s = uistyle("Interpreter","html");
%             addStyle(app.UITable,s);
            

you can see that, when I tried to use HTML to draw line, it couldn't.

My expect.

Or has marker is excilent.

Do anyone have idea? Could you give me.

Thank you so much

uitable doesn't have a html interpreter. So... below is my approach to this issue.

app.UITable.Data = table(["–––––o–––––"; "–––––o–––––"], ["tan(t)"; "sin(t)"], [true; true]);
s1 = uistyle('FontColor','b', 'HorizontalAlignment', 'center', 'FontWeight', 'bold');
s2 = uistyle('FontColor','r', 'HorizontalAlignment', 'center', 'FontWeight', 'bold');
addStyle(app.UITable, s1, "cell", [1,1])
addStyle(app.UITable, s2, "cell", [2,1])

You will get...

I think a slider could be a solution. Not as beautiful as controlling directly the panel, but...

% Value changing function: Slider
function SliderValueChanging(app, event)
    x1 = (event.Value+1)/2;
    x2 = 1-x1;
    app.GridLayout.ColumnWidth(1:2) = {sprintf('%fx', x1), sprintf('%fx', x2)};
end
