hello

i want to reference axes by a tag and then fill the plot with fill(). but after using fill() the tag of the axes is deleted as you can see in the example:

fig = figure(1);
ax = axes('Parent', fig, 'Tag', 'axTag', 'Units', 'characters', 'Position', [10 10 5 5]);

till now i still can reference the axes by the tag:

get(ax, 'Tag')
ans =
axTag

or:

get(gca, 'Tag')
ans =
axTag

but when i fill the plot with:

fill([0 0 1], [0 1 1], 'r')

get(ax, 'Tag') as well as get(gca, 'Tag') return
ans =
''

so why do i loose the tag then? how can i avoid that?
thx

one of the solutions

ax=axes('tag','atag');
hold on;
fill([0,0,1],[0,1,1],[1,0,0]);
get(ax,'tag');
% ans = atag

High-level plotting functions, like PLOT and FILL, respond to the NextPlot
setting as described in that document.
