This is not what I want, of course: I don't want to do without F4. But if I then press Cancel, F4 is deleted. I have to press OK if I want to keep F4 there. After this, it doesn't matter how many times I select Add function graph: always appears F4's definition dialog. When I get tired of this I write my new function over F4, changing its functionality F4(x)=. After this it may be F5 that has the same problem, or it can temporaly work properly letting me define F2 or F6 (!) before forcing me to overwrite F5 or F7.

As an example of this, feel free to download one of my projects (7.5 kB). I've deleted all the worksheets and almost all the graphs. Only functions and one graph left. Active layer #2 (the one below) and try to add a new function!

Has anyone experienced something similar? Am I doing something wrong? Is there any way to let me name the functions I create, or is it always an automatic process? Has this auto-naming process a correspondant script that I could check or modify?

Thanks in advance.

Some minor details:

- You missed a semicolon at the end... didn't you?

del -m ErrorProc;

- On your third line from the end shouldn't you use curly brackets?

def ErrorProc {del %B};

(I don't understand very well the use of this last three lines, but I imagine it has to do with some internal use of the ErrorProc macro by the set command...)

if I run this new newfunction macro from the script window and I cancel the operation in the dialog, I get a non-important #Command error! caused by... what?

Glad you are all set with this one. The semi-colon should definitely be there and I think the [ ]'s in place of the { }'s is an archaic notation. Anyway, I updated the post...thanks!

The set %B; command opens the Plot Details dialog box providing an interface to enter the new function. The ERRORPROC macro gets executed if you click the Cancel button in the Plot Details dialog box. This is why your old existing functions were deleted as you reported above. My naming fix should prevent this problem from happening anymore.

I enjoyed working on this problem...thanks.

Try:

GetEnumWin Function;
NewFunction;

following your instructions, I first get also Layer2-F3 with its many-decimals-equation in that dialog.

But after using the Cancel-button and immediately trying to add a function-graph again, I then get Layer2-F2 with a different, short equation: 4.0e4*x^(-1). ?!

Now, using Cancel again, suddenly leads to F1. (Couldn´t decrease it to F-1 :-)

Strange!

Thanks for reporting this problem. I will notify our developers. In the mean time, I have a work around for you. Open the text file MACROS.CNF (in your origin software folder) using any text editor and copy/paste the script below at the very end of the file. Save and then exit from the MACROS.CNF file. After restarting Origin you should be all set...let me know if you still have problems.
