Re: Fitting in current xrange

I suppose you are talking about this part of the help:

I am aware that I can use this to specify a range /if I know the boundaries/. E.g., I can write:

| fit [0:10] f(x) 'data.dat'...

or even

| fit [xmin:xmax] f(x) ...

but in these cases, I have to know in advance the boundaries I want to use for fitting. What I am looking for are things like one of the following:

| fit CURRENT_X_RANGE f(x)...
| fit [XRANGE_MIN:XRANGE_MAX] f(x)

My problem is: I do not know the values in advance, because I want to use wxt's interactive features to select a region of my graph, and then run the fit with the /current visible region/. I don't want to run show xrange and copy the values into fit, because finally, I want to run the fit by just hitting a hotkey.

I hope I was able to make clear that my problem is not literally the first line of the documentation.

Best regards,
Anton
