Hi, I am currently working on a project where I need exactly this integration capability. Thanks a lot. I have x-ray fluorescence spectra taken at different times, where I want to plot the signal along the time axis integrated over the width of the peaks of interest along the orthogonal energy axis. Actually, this is not the first time this topic appears on the list. Also, in a different software project, which analyses diffraction data taken with a CCD camera over time, we have implemented the same integration or averaging functionality, and have found it to be one of the most useful functions in everyday work. I would therefore propose or request to add an additional tool to dx that offers this integration or averaging right out of the box. The module would look like slab at the input side and like slice at the output, averaging over the index range defined at the input and reducing the dimensionality by removing the one in the averaging direction. I think that in many cases where one currently uses slice, such an integration could be more convenient. In my case, for example, a time integration of all spectra would give me a low-noise integrated spectrum containing all peaks that I need to stretch and shift the energy axis to the known elemental line positions, much more convenient than doing the adaptation at different slice positions with high noise levels. Just wondering whether I am the only one in need of such a tool.
