GUI & data plotting

[barney75]

Hi guys,
I have to plot a serie of data (x,y) that are read from a text file. How can is it possible to store the data in a variable in the workspace in order to make it possible to access/process the data after each action (for example after pushing a button etc. etc.) without reading the txt file each time (it's a huge file and it requires some minutes to be read).

Thanks in advance

Bye

Hi,
got around it, using the assignin and evalin I solved the problem storing the data in the base workspace and extrancting later on when I need them.

If you are fiddling with GUIs in Matlab, there are ways of storing data local to the GUI. Each graphical element (including GUI ones) has a 'userdata' attribute that can be used to store almost anything.

Also, read up on setappdata and getappdata. Very useful in GUI programming.
