Thx for providing DynamicLegend, I really like it!
One question though: Is it possible, to add new items on the bottom instead of a vertical legend? That would be really great. Or maybe this even works with a general command to flip the legend after it was generated? But I couldn’t find such thing 🙁

Thx & Best,
Manuel

Thanks a lot man for letting us know about -DynamicLegend…i was really needed this kind of function as i was using for loop and in that plotting plot for n times while required to have legends for each plot…Again Thanks a lot

In reply to Clark.

@Clark – if your plot contains so many dynamic plot lines, then for both visual design and performance reasons I would strongly suggest using some other mechanism…

Thanks for letting the world know about the -DynamicLegend feature. Note that it appears to be limited to at most 50 entries, at least in R2015b. Plots beyond the first 50 simply don’t appear in the legend created by legend(‘-DynamicLegend’)

In reply to Stephan. @Stephan - yes: You can access the Refresh uicontextmenu item (and any other context-menu item) directly from the legend axes, and then run it via the hgfeval function, as follows:

hLegend = findall(gcf,'tag','legend');
uic = get(hLegend,'UIContextMenu');
uimenu_refresh = findall(uic,'Label','Refresh');
callback = get(uimenu_refresh,'Callback');
hgfeval(callback,[],[]);

For the record, this invokes the refresh_cb function within %matlabroot%/toolbox/matlab/scribe/@scribe/@legend/methods.m. You can place a breakpoint there to see exactly what it does internally.

In reply to Teodor. @Teodor - try placing a drawnow after plotting the lines and before trying to access the hidden ScribeLegendListeners property. It is also possible that you are trying to access this property on a handle of another object (maybe one of the line plots, or a figure, or another axes), rather than the handle of the axes that holds the plots for the requested legend.
