Hello,
I'd like to pass data to a user defined fucntion that is run every time that the data tip is used in order that I can display further information about the data on the graph interactively.
The code in the main GUI looks like:
cursorMode = datacursormode(gcf);
set(handles.cursorMode, 'enable','on', 'UpdateFcn', @setDataTipTxtFFT)
This calls:
function output_txt = setDataTipTxtFFT(obj,event_obj)
pos = get(event_obj,'Position');
line_id = get(event_obj,'Target')
Freq = pos(1)
Amp = pos(2)
s1 = sprintf('freq = %1.4g Telsa', Freq);
s2 = sprintf('amp = %1.4g', Amp);
output_txt = {s1; s2; s3};
-----------------------------------------------------------
What I would like to do is cross reference the index of the various plots with the index of the loaded files which are stored in the main gui's handle structure.
I don't seem to be able to just call the handles.LoadedFileIndex or such like inside the function @setDataTipTxtFFT
I tried passing handles in the variable list of @setDataTipTxtFFT
Should this work, and if not, could you suggest what the most eficient way of doing this might be. I though the handles structure was meant to get around the defining of global variables, which I could access with setappdata and getappdata
Iss this one of those instances where using this method is unavoidable?
Thanks!
