This creates a point and an invisible text. If you click on the point, the ButtonDownFcn is triggered and the visibility is toggled:
function main
axes;
Text1H = text(0.5, 0.5, 'Center', 'Visible', 'off');
plot(0.5, 0.5, 'ro', 'ButtonDownFcn', {@toggleText, Text1H});
Text2H = text(0.25, 0.25, 'Down Left', 'Visible', 'off');
plot(0.25, 0.25, 'bo', 'ButtonDownFcn', {@toggleText, Text2H});
end
function toggleText(LineH, EventData, TextH)
vis = get(TextH, 'Visible');
if strcmp(vis, 'on')
set(TextH, 'Visible', 'off');
else
set(TextH, 'Visible', 'on');
end
end
