skip legend entries in dynamiclegend

Hi, I wrote a GUI-Programm where you can load a Data-Table and make different plots by clicking one of the buttons. Thode plots are all made in the same axis. The dynamiclegend function allow to update the legend for each plot. There is one loop, in wich plots are created and every one of them has a text labeling it next to it. So these plots shouldnt have any legend entries. Unfortunatly by plotting these (smoothingspline-fits) there is a "data"- and a "fitted curve"-entry in the legend. Ive been googling a lot and reading a lot of matlab-help concearning this matter and just cant figure it out. Hope this works without publishing my code. thanks

Take a look here: http://undocumentedmatlab.com/blog/handle-graphics-behavior

Specifically:

hasbehavior(hLine, 'legend', false);   % line will not be in legend
hasbehavior(hLine, 'legend', true);    % line will be in legend

thanks you! Now the "data"-entry is hidden, but it still shows the "fitted curve"-entry. Here's my code, wich is located under a function for pushbutton_callback.

ok the solution is

                    DK_Smooth=fit(n_DK,M_DK,'Smoothingspline','SmoothingParam',1)

                    h(d,:)=plot(DK_Smooth,n_DK,M_DK)
                    hasbehavior(h(d), 'legend', false); 
                    hasbehavior(h(d,2), 'legend', false);

cheers :)

I don't see any function named DYNAMICLEGEND in the documentation. Are you just calling LEGEND (perhaps with the "show" option) each time a new entry is added to the axes?

If so, call LEGEND with a vector of handles of objects you want to appear in the legend. If you have the DisplayName property of those objects set, you can call LEGEND just with the vector of handles.

 % Create two plots
 h = plot(1:10, 1:10, 'DisplayName', 'line');
 hold on
 h2 = plot(1:10, (1:10).^2./10, 'DisplayName', 'curve');

 % Display just 'line' in the legend
 legend(h)

 % Display just 'curve' in the legend
 legend(h2)

 % Display both in the legend
 legend([h, h2])

hmm that wont work or will be complicated because every one of the plot is created in a different callback-function (function pushbutton3-callback....4...5...6). Wich means I cant access the plots globally just like that to control the legend feature for each of them,right?. Anywy the dynamiclegend seems to be a rarely nown feature http://undocumentedmatlab.com/blog/legend-semi-documented-feature
