plot legend disappears after resize
显示 更早的评论
the legend of my bodeplot disappears after i resize the figure with my mouse
b = [0 2 3; 1 2 1];
a = [1 0.4 1];
[A,B,C,D] = tf2ss(b,a);
statespace = ss(A,B,C,D) ;
f = figure;
p = bodeplot(statespace(1,1));
setoptions(p,'FreqUnits','Hz','PhaseVisible','off');
legend('test','Location','southwest');
set(f, 'ResizeFcn', @(varargin) legend('test','Location','southwest'))
solves the problem but maybe there is a better solution.

A "bodeplot" creates more than one axes and when calling "legend" without specifying the parent axes, MATLAB takes the last active axes which might be an invisible one leading to undesired behavior. Overall it is the best to specify the axes as input to which the legend refers, e.g.
legend(findall(gcf,'type','axes','visible','on'),'test','Location','southwest');
This will keep the legend visible when resizing the figure.
