Hi,

I am modifying the data tips to be visualized in the data cursor. Everything works fine, but when I save the figure .fig with saveas I lose all the changes I have done to the data tips.

Interestingly if I use instead the "File-> Save as" manually from the figure GUI, the changes to the figure are preserved. Am I missing something in the saveas command? The code is something like this:

figA=figure('name','Test');

h=plot(....);

addTagCursor(h,...);

hold on

h=plot(...);

addTagCursor(h,...);

saveas(figA, 'mypicture.fig');

Thanks for help!

If you post some code, which runs after a copy&paste, we could try to reproduce the problem. Hiding the interesting parts by "..." does not allow to test exactly what's going on.

Hi, Thanks for help! I have tried many option, e.g. saveas(gcf,..), hgsave, etc. but with no luck so far. When I open the saved picture all the data tips I modified disappear.

Here is the code:

function test

a=[495156 495216 495276 495476 495516 495576 495676 495716 526396 542016]

b=[9790787 9798246 9805705 9836650 9843961 9855805 9878359 9883467 16173228 20990681]

c=[3 5; 6495542 7495542; 9848605 19848605; 432 657]

figB=figure('name','Test');

h=plot(a,ones(1,length(a)),'*r');

addTagCursor1(h, [cellstr(num2str(b'))... repmat(cellstr(num2str(-1)),length(cellstr(num2str(b'))),1)... repmat(cellstr(num2str(-1)),length(cellstr(num2str(b'))),1)]);

hold on

h=plot(c(2,:),ones(1,size(c,2)),'hk');

addTagCursor1(h, [cellstr(num2str(c(3,:)'))... cellstr(num2str(c(1,:)'))... cellstr(num2str(c(4,:)'))]);

hold on

saveas(figB,strcat(pwd,'\test.fig'));

end

function addTagCursor1(h,data)

set(h,'userdata',data)

dcmH = datacursormode(gcf);

set(dcmH, 'enable','on', 'UpdateFcn',@cursorUpdateFcn1, 'NewDataCursorOnClick',false);

end

function output_txt = cursorUpdateFcn1(obj,event_obj)

pos = get(event_obj,'Position');

labels = get(get(event_obj,'Target'),'UserData');

xvals = get(get(event_obj,'Target'),'XData');

yvals = get(get(event_obj,'Target'),'YData');

datapoint = find( (xvals==pos(1))&(yvals==pos(2)) );

output_txt = {['Time: ',num2str(pos(1))];... ['Y_axis: ',num2str(pos(2))];... ['Log Line: ',labels{datapoint,1}];... ['Value1: ',labels{datapoint,2}];... ['Value2: ',labels{datapoint,3}]};

end

You can use the debugger to check, what's going on inside saveas. Simply set a breakpoint inside this function, step through the code line by line and find out, which command influences the data tips.
