I have files of different file formats e.g, csv, ras, raw, asc. I want to plot 2theta vs counts for this I plotted columns '#twotheta' & 'yobs' (in csv file) on X and Y axes respectively. But the curve I got doesn't appear to resemble proper XRR of the sample. I am wondering if I did something wrong. Is there a manual from which I can understand the file format? Or any software or module which can be used to read the data?
