    hello,

    when using gauss fit: how may I define coordinates of the vertex? (I do not want to choose the vertex by click on the point in the graph.)

    might anyone help me, please?

    If you are using the standard gauss fit formula { y0+A*sqrt(2/PI)/w*exp(-2*((x-xc)/w)^2) }, the 'x' coordinate of the vertex is always "xc" in the results log. And the 'y' coordinate is the product { A*sqrt(2/PI)/w }.

    Thanks a lot, fellype. I actually had another question. But your solution also solves my problem.
    (I didn't know, that I may use the first click for "approximate vertex" and the second one for "exactly" vertex when looking at the bottom -> coordinates.)
