Re: datacursor for Octave 5.2.0(Windows)

[Debajyoti Datta]

Hi Markus, 

 By datacursor patch folder I was referring to the v3 folder in this link below

https://savannah.gnu.org/patch/?9280#comment3

Somehow things are working now.I have placed the above mentioned folder in working directory. After creating any plot, I have to open and run from the folder _datacursor_menu_.m program. After that only data menu appears in the figure and I can select point whose coordinates are to be displayed.

Thanks for your help.

I still don't know what you mean by "datacursor patch folder". The one I found is just one single .m file...

The current working directory is the directory that is displayed in the top toolbar in the Octave GUI. It is also returned if you execute "pwd" at the Octave "Command Window". You could move the function you want to execute to that directory.
Alternatively, you could add the path where the function is stored to Octave's search path. Assuming the file is stored in the folder "C:\My_Octave_Files", execute the following at the Octave "Command Window":
addpath ('C:\My_Octave_Files')

After that, call the function like any other. E.g.:
plot(1:10);
datacursor()


HTH,
